Alain Badiou

Alain Badiou (French: [alɛ̃ badju] (listen) ; born 17 January 1937) is a French philosopher, formerly chair ofPhilosophy at the École Normale Supérieure (ENS) and founder of the faculty of Philosophy of the Université deParis VIII with Gilles Deleuze, Michel Foucault and Jean-François Lyotard. Badiou has written about the concepts ofbeing, truth, event and the subject in a way that, he claims, is neither postmodern nor simply a repetition of modernity.Badiou has been involved in a number of political organisations, and regularly comments on political events. Badiouargues for resurrecting the idea of communism.

1.1 Biography

Badiou is the son of mathematician and member of the Resistance in France during World War II Raymond Ba-diou (1905–1996). He was a student at the Lycée Louis-Le-Grand and then the École Normale Supérieure (1955–1960).[1] In 1960, he wrote his diplôme d'études supérieures (roughly equivalent to an MA thesis) on Spinoza forGeorges Canguilhem (the topic was “Demonstrative Structures in the First Two Books of Spinoza’s Ethics", "Struc-tures démonstratives dans les deux premiers livres de l'Éthique de Spinoza").[2] He taught at the lycée in Reims from1963 where he became a close friend of fellow playwright (and philosopher) François Regnault,[3] and published acouple of novels before moving first to the faculty of letters of the University of Reims (the collège littéraire univer-sitaire)[4] and then to the University of Paris VIII (Vincennes-Saint Denis) in 1969.[5] Badiou was politically activevery early on, and was one of the founding members of the Unified Socialist Party (PSU). The PSU was particularlyactive in the struggle for the decolonization of Algeria. He wrote his first novel, Almagestes, in 1964. In 1967 hejoined a study group organized by Louis Althusser, became increasingly influenced by Jacques Lacan and became amember of the editorial board of Cahiers pour l'Analyse.[5] By then he “already had a solid grounding in mathematicsand logic (along with Lacanian theory)",[5] and his own two contributions to the pages of Cahiers “anticipate manyof the distinctive concerns of his later philosophy”.[5]

The student uprisings ofMay 1968 reinforced Badiou’s commitment to the far Left, and he participated in increasinglymilitant groups, such as the Union des communistes de France marxiste-léniniste (UCFml). To quote Badiou himself,the UCFml is “the Maoist organization established in late 1969 by Natacha Michel, Sylvain Lazarus, myself and afair number of young people”.[6] During this time, Badiou joined the faculty of the newly founded University of ParisVIII/Vincennes-Saint Denis which was a bastion of counter-cultural thought. There he engaged in fierce intellectualdebates with fellow professors Gilles Deleuze and Jean-François Lyotard, whose philosophical works he consideredunhealthy deviations from the Althusserian program of a scientific Marxism.In the 1980s, as both Althusserian Marxism and Lacanian psychoanalysis went into decline (after Lacan died andAlthusser was committed to a psychiatric hospital), Badiou publishedmore technical and abstract philosophical works,such as Théorie du sujet (1982), and his magnum opus, Being and Event (1988). Nonetheless, Badiou has neverrenounced Althusser or Lacan, and sympathetic references to Marxism and psychoanalysis are not uncommon in hismore recent works (most notably Petit panthéon portatif/Pocket Pantheon).[7][8]

He took up his current position at the ENS in 1999. He is also associated with a number of other institutions, such asthe Collège International de Philosophie. He was a member of “L'Organisation Politique” which, as mentioned above,he founded in 1985 with some comrades from the Maoist UCFml. This organization disbanded in 2007, accordingto the French Wikipedia article (linked to in the previous sentence). In 2002, he was a co-founder of the Centre

1.2. KEY CONCEPTS 3

International d'Etude de la Philosophie Française Contemporaine, alongside Yves Duroux and his former studentQuentin Meillassoux.[9] Badiou has also enjoyed success as a dramatist with plays such as Ahmed le Subtil.In the last decade, an increasing number of Badiou’s works have been translated into English, such as Ethics, Deleuze,Manifesto for Philosophy, Metapolitics, and Being and Event. Short pieces by Badiou have likewise appeared inAmerican and English periodicals, such as Lacanian Ink, New Left Review, Radical Philosophy, Cosmos and Historyand Parrhesia. Unusually for a contemporary European philosopher his work is increasingly being taken up bymilitants in countries like India, the Democratic Republic of Congo and South Africa.Recently Badiou got into a fierce controversy within the confines of Parisian intellectual life. It started in 2005 with thepublication of his “Circonstances 3: Portées du mot 'juif'" – The Uses of the Word “Jew”.[10] This book generateda strong response with calls of Badiou being labelled Anti-Semitic. The wrangling became a cause célèbre witharticles going back and forth in the French newspaper Le Monde and in the cultural journal “Les temps modernes.”Linguist and Lacanian philosopher Jean-Claude Milner, a past president of Jacques Derrida's Collège internationalde philosophie, has accused Badiou of Anti-Semitism.[11]

In 2014–15, Badiou had the role of Honorary President at The Global Center for Advanced Studies.[12]

1.2 Key concepts

Badiou makes repeated use of several concepts throughout his philosophy. One of the aims of his thought is to showthat his categories of truth are useful for any type of philosophical critique. Therefore, he uses them to interrogateart and history as well as ontology and scientific discovery. Johannes Thumfart argues that Badiou’s philosophy canbe regarded as a contemporary reinterpretation of Platonism.[13]

1.2.1 Conditions

According to Badiou, philosophy is suspended from four conditions (art, love, politics, and science), each of them fullyindependent “truth procedures.” (For Badiou’s notion of truth procedures, see below.) Badiou consistently maintainsthroughout his work (but most systematically inManifesto for Philosophy) that philosophy must avoid the temptationto suture itself (that is, to hand over its entire intellectual effort) to any of these independent truth procedures. Whenphilosophy does suture itself to one of its conditions (and Badiou argues that the history of philosophy during thenineteenth and twentieth centuries is primarily a history of sutures), what results is a philosophical “disaster.” Conse-quently, philosophy is, according to Badiou, a thinking of the compossibility of the several truth procedures, whetherthis is undertaken through the investigation of the intersections between distinct truth procedures (the intersectionof art and love in the novel, for instance), or whether this is undertaken through the more traditionally philosophicalwork of addressing categories like truth or the subject (concepts that are, as concepts, external to the individual truthprocedures, though they are functionally operative in the truth procedures themselves). For Badiou, when philosophyaddresses the four truth procedures in a genuinely philosophical manner, rather than through a suturing abandon-ment of philosophy as such, it speaks of them with a theoretical terminology that marks its philosophical character:“inaesthetics” rather than art; metapolitics rather than politics; ontology rather than science; etc.Truth, for Badiou, is a specifically philosophical category. While philosophy’s several conditions are, on their ownterms, “truth procedures” (i.e., they produce truths as they are pursued), it is only philosophy that can speak of theseveral truth procedures as truth procedures. (The lover, for instance, does not think of her love as a question oftruth, but simply and rightly as a question of love. Only the philosopher sees in the true lover’s love the unfolding ofa truth.) Badiou has a very rigorous notion of truth, one that is strongly against the grain of much of contemporaryEuropean thought. Badiou at once embraces the traditional modernist notion that truths are genuinely invariant(always and everywhere the case, eternal and unchanging) and the incisively postmodernist notion that truths areconstructed through processes. Badiou’s theory of truth, exposited throughout his work, accomplishes this strangemixture by uncoupling invariance from self-evidence (such that invariance does not imply self-evidence), as well asby uncoupling constructedness from relativity (such that constructedness does not lead to relativism).The idea, here, is that a truth’s invariance makes it genuinely indiscernible: because a truth is everywhere and alwaysthe case, it passes unnoticed unless there is a rupture in the laws of being and appearance, during which the truthin question becomes, but only for a passing moment, discernible. Such a rupture is what Badiou calls an event,according to a theory originally worked out in Being and Event and fleshed out in important ways in Logics of Worlds.The individual who chances to witness such an event, if he is faithful to what he has glimpsed, can then introducethe truth by naming it into worldly situations. For Badiou, it is by positioning oneself to the truth of an event that a

human animal becomes a subject; subjectivity is not an inherent human trait. According to a process or procedurethat subsequently unfolds only if those who subject themselves to the glimpsed truth continue to be faithful in thework of announcing the truth in question, genuine knowledge is produced (knowledge often appears in Badiou’s workunder the title of the “veridical”). While such knowledge is produced in the process of being faithful to a truth event,it should be noted that, for Badiou, knowledge, in the figure of the encyclopedia, always remains fragile, subject towhat may yet be produced as faithful subjects of the event produce further knowledge. According to Badiou, truthprocedures proceed to infinity, such that faith (fidelity) outstrips knowledge. (Badiou, following both Lacan andHeidegger, distances truth from knowledge.) The dominating ideology of the day, which Badiou terms “democraticmaterialism,” denies the existence of truth and only recognizes "bodies" and "languages.” Badiou proposes a turntowards the "materialist dialectic,” which recognizes that there are only bodies and languages, except there are alsotruths.

1.2.2 Inaesthetic

In Handbook of Inaesthetics Badiou both draws on the original Greek meaning and the later Kantian concept of“aesthesis” as “material perception” and coins the phrase “inaesthetic” to refer to a concept of artistic creation thatdenies “the reflection/object relation” yet, at the same time, in reaction against the bourgeois idea of mimesis, orpoetic reflection of “nature”, he affirms that art is “immanent” and “singular”. Art is immanent in the sense that itstruth is given in its immediacy in a given work of art, and singular in that its truth is found in art and art alone—hencereviving the ancient materialist concept of “aesthesis”. His view of the link between philosophy and art is tied intothe motif of pedagogy, which he claims functions so as to “arrange the forms of knowledge in a way that some truthmay come to pierce a hole in them”. He develops these ideas with examples from the prose of Samuel Beckett andthe poetry of Stéphane Mallarmé and Fernando Pessoa (who he argues has developed a body of work that philosophyis currently incapable of incorporating), among others.

1.3 Introduction to Being and Event

The major propositions of Badiou’s philosophy all find their basis in Being and Event, in which he continues hisattempt (which he began in Théorie du sujet) to reconcile a notion of the subject with ontology, and in particular post-structuralist and constructivist ontologies.[14] A frequent criticism of post-structuralist work is that it prohibits, throughits fixation on semiotics and language, any notion of a subject. Badiou’s work is, by his own admission,[15] an attemptto break out of contemporary philosophy’s fixation upon language, which he sees almost as a straitjacket. This effortleads him, inBeing and Event, to combine rigorousmathematical formulae with his readings of poets such asMallarméand Hölderlin and religious thinkers such as Pascal. His philosophy draws upon both 'analytical' and 'continental'traditions. In Badiou’s own opinion, this combination places him awkwardly relative to his contemporaries, meaningthat his work had been only slowly taken up.[16] Being and Event offers an example of this slow uptake, in fact: it wastranslated into English only in 2005, a full seventeen years after its French publication.As is implied in the title of the book, two elements mark the thesis of Being and Event: the place of ontology, or'the science of being qua being' (being in itself), and the place of the event – which is seen as a rupture in being– through which the subject finds realization and reconciliation with truth. This situation of being and the rupturewhich characterizes the event are thought in terms of set theory, and specifically Zermelo–Fraenkel set theory (withthe axiom of choice), to which Badiou accords a fundamental role in a manner quite distinct from the majority ofeither mathematicians or philosophers.

1.3.1 Mathematics as ontology

For Badiou the problem which the Greek tradition of philosophy has faced and never satisfactorily dealt with is thatwhile beings themselves are plural, and thought in terms of multiplicity, being itself is thought to be singular; that is,it is thought in terms of the one. He proposes as the solution to this impasse the following declaration: that the one isnot. This is why Badiou accords set theory (the axioms of which he refers to as the Ideas of the multiple) such stature,and refers to mathematics as the very place of ontology: Only set theory allows one to conceive a 'pure doctrine ofthe multiple'. Set theory does not operate in terms of definite individual elements in groupings but only functionsinsofar as what belongs to a set is of the same relation as that set (that is, another set too). What individuates a set,therefore, is not an existential positive proposition, but other multiples whose properties (i.e., structural relations)validate its presentation. The structure of being thus secures the regime of the count-as-one. So if one is to think of

Page 5: Set Theorists 1

1.3. INTRODUCTION TO BEING AND EVENT 5

a set – for instance, the set of people, or humanity – as counting as one, the multiple elements which belong to thatset are secured as one consistent concept (humanity), but only in terms of what does not belong to that set. Whatis crucial for Badiou is that the structural form of the count-as-one, which makes multiplicities thinkable, implies(somehow or other) that the proper name of being does not belong to an element as such (an original 'one'), but ratherthe void set (written Ø), the set to which nothing (not even the void set itself) belongs. It may help to understand theconcept 'count-as-one' if it is associated with the concept of 'terming': a multiple is not one, but it is referred to with'multiple': one word. To count a set as one is to mention that set. How the being of terms such as 'multiple' doesnot contradict the non-being of the one can be understood by considering the multiple nature of terminology: forthere to be a term without there also being a system of terminology, within which the difference between terms givescontext and meaning to any one term, is impossible. 'Terminology' implies precisely difference between terms (thusmultiplicity) as the condition for meaning. The idea of a term without meaning is incoherent, the count-as-one is astructural effect or a situational operation; it is not an event of 'truth'. Multiples which are 'composed' or 'consistent'are count-effects. 'Inconsistent multiplicity' [meaning?] is [somehow or other] 'the presentation of presentation.'Badiou’s use of set theory in this manner is not just illustrative or heuristic. Badiou uses the axioms of Zermelo–Fraenkel set theory to identify the relationship of being to history, Nature, the State, and God. Most significantlythis use means that (as with set theory) there is a strict prohibition on self-belonging; a set cannot contain or belongto itself. This results from the axiom of foundation – or the axiom of regularity – which enacts such a prohibition(cf. p. 190 in Being and Event). (This axiom states that every non-empty set A contains an element y that is disjointfrom A.) Badiou’s philosophy draws two major implications from this prohibition. Firstly, it secures the inexistenceof the 'one': there cannot be a grand overarching set, and thus it is fallacious to conceive of a grand cosmos, a wholeNature, or a Being of God. Badiou is therefore – against Georg Cantor, from whom he draws heavily – staunchlyatheist. However, secondly, this prohibition prompts him to introduce the event. Because, according to Badiou, theaxiom of foundation 'founds’ all sets in the void, it ties all being to the historico-social situation of the multiplicities ofde-centred sets – thereby effacing the positivity of subjective action, or an entirely 'new' occurrence. And whilst this isacceptable ontologically, it is unacceptable, Badiou holds, philosophically. Set theory mathematics has consequently'pragmatically abandoned' an area which philosophy cannot. And so, Badiou argues, there is therefore only onepossibility remaining: that ontology can say nothing about the event.Several critics have questioned Badiou’s use of mathematics. Mathematician Alan Sokal and physicist Jean Bricmontwrite that Badiou proposes, with seemingly “utter seriousness,” a blending of psychoanalysis, politics and set theorythat they contend is preposterous.[17] Similarly, philosopher Roger Scruton has questioned Badiou’s grasp of thefoundation of mathematics, writing in 2012:

There is no evidence that I can find in Being and Event that the author really understands what he istalking about when he invokes (as he constantly does) Georg Cantor’s theory of transfinite cardinals, theaxioms of set theory, Gödel’s incompleteness proof or Paul Cohen’s proof of the independence of thecontinuum hypothesis. When these things appear in Badiou’s texts it is always allusively, with fragmentsof symbolism detached from the context that endows them with sense, and often with free variables andbound variables colliding randomly. No proof is clearly stated or examined, and the jargon of set theoryis waved like a magician’s wand, to give authority to bursts of all but unintelligible metaphysics.[18]

An example of a critique from a mathematician’s point of view is the essay 'Badiou’s Number: A Critique of Math-ematics as Ontology' by Ricardo L. Nirenberg and David Nirenberg, which takes issue in particular with Badiou’smatheme of the Event in Being and Event, which has already been alluded to in respect of the 'axiom of foundation'above. Nirenberg and Nirenberg write:

Rather than being defined in terms of objects previously defined, ex is here defined in terms of itself;you must already have it in order to define it. Set theorists call this a not-well-founded set. This kindof set never appears in mathematics—not least because it produces an unmathematical mise-en-abîme:if we replace ex inside the bracket by its expression as a bracket, we can go on doing this forever—and so can hardly be called “a matheme.”' (http://criticalinquiry.uchicago.edu/uploads/pdf/nirenbergs_badiousnumber_complete.pdf, pp. 598–9)

1.3.2 The event and the subject

The principle of the event is where Badiou diverges from the majority of late twentieth century philosophy and socialthought, and in particular the likes of Foucault, Butler, Lacan and Deleuze, among others. In short, it represents that

Page 6: Set Theorists 1

6 CHAPTER 1. ALAIN BADIOU

Drawing from 18 November 2006 “Truth procedure in politics” lecture

which is outside ontology. Badiou’s problem here is, unsurprisingly, the question of how to 'make use' of that whichcannot be discerned. But it is a problem he views as vital, because if one constructs the world only from that whichcan be discerned and therefore given a name, it results in either the destitution of subjectivity and the removal of thesubject from ontology (the criticism continually leveled at Foucault’s discursive universe), or the Panglossian solutionof Leibniz: that God is language in its supposed completion.Badiou again turns here to mathematics and set theory – Badiou’s language of ontology – to study the possibility of anindiscernible element existing extrinsically to the situation of ontology. He employs the strategy of the mathematicianPaul J. Cohen, using what are called the conditions of sets. These conditions are thought of in terms of domination, adomination being that which defines a set. (If one takes, in binary language, the set with the condition 'items markedonly with ones’, any item marked with zero negates the property of the set. The condition which has only ones is thusdominated by any condition which has zeros in it [cf. p. 367-71 in Being and Event].) Badiou reasons using theseconditions that every discernible (nameable or constructible) set is dominated by the conditions which don't possessthe property that makes it discernible as a set. (The property 'one' is always dominated by 'not one'.) These setsare, in line with constructible ontology, relative to one’s being-in-the-world and one’s being in language (where setsand concepts, such as the concept 'humanity', get their names). However, he continues, the dominations themselvesare, whilst being relative concepts, not necessarily intrinsic to language and constructible thought; rather one canaxiomatically define a domination – in the terms of mathematical ontology – as a set of conditions such that anycondition outside the domination is dominated by at least one term inside the domination. One does not necessarilyneed to refer to constructible language to conceive of a 'set of dominations’, which he refers to as the indiscernible set,or the generic set. It is therefore, he continues, possible to think beyond the strictures of the relativistic constructibleuniverse of language, by a process Cohen calls forcing. And he concludes in following that while ontology can markout a space for an inhabitant of the constructible situation to decide upon the indiscernible, it falls to the subject –about which the ontological situation cannot comment – to nominate this indiscernible, this generic point; and thusnominate, and give name to, the undecidable event. Badiou thereby marks out a philosophy by which to refute theapparent relativism or apoliticism in post-structuralist thought.Badiou’s ultimate ethical maxim is therefore one of: 'decide upon the undecidable'. It is to name the indiscernible, the

Page 7: Set Theorists 1

1.4. L'ORGANISATION POLITIQUE 7

generic set, and thus name the event that re-casts ontology in a new light. He identifies four domains in which a subject(who, it is important to note, becomes a subject through this process) can potentially witness an event: love, science,politics and art. By enacting fidelity to the event within these four domains one performs a 'generic procedure', whichin its undecidability is necessarily experimental, and one potentially recasts the situation in which being takes place.Through this maintenance of fidelity, truth has the potentiality to emerge.In line with his concept of the event, Badiou maintains, politics is not about politicians, but activism based on thepresent situation and the evental [sic] (his translators’ neologism) rupture. So too does love have this characteristic ofbecoming anew. Even in science the guesswork that marks the event is prominent. He vigorously rejects the tag of'decisionist' (the idea that once something is decided it 'becomes true'), but rather argues that the recasting of a truthcomes prior to its veracity or verifiability. As he says of Galileo (p. 401):

When Galileo announced the principle of inertia, he was still separated from the truth of the new physicsby all the chance encounters that are named in subjects such as Descartes or Newton. How could he, withthe names he fabricated and displaced (because they were at hand – 'movement', 'equal proportion', etc.),have supposed the veracity of his principle for the situation to-come that was the establishment of modernscience; that is, the supplementation of his situation with the indiscernible and unfinishable part that onehas to name 'rational physics’?

While Badiou is keen to reject an equivalence between politics and philosophy, he correlates nonetheless his politicalactivism and skepticism toward the parliamentary-democratic process with his philosophy, based around singular,situated truths, and potential revolutions.

1.4 L'Organisation Politique

Alain Badiou is a founding member (along with Natacha Michel and Sylvain Lazarus) of the militant French politicalorganisation L'Organisation Politique, which was active from 1985 until it disbanded in 2007.[19] It called itself apost-party organization concerned with direct popular intervention in a wide range of issues (including immigration,labor, and housing). In addition to numerous writings and interventions, L'Organisation Politique highlighted theimportance of developing political prescriptions concerning undocumented migrants (les sans papiers), stressing thatthey must be conceived primarily as workers and not immigrants.[20]

Andreas Blass

Andreas Raphael Blass (born October 27, 1947 in Nuremberg) is a mathematician, currently a professor at theUniversity of Michigan. He specializes in mathematical logic, particularly set theory, and theoretical computer sci-ence.Blass graduated from the University of Detroit, where he was a Putnam Fellow, in 1966 with a B.S. in physics.He received his Ph.D. in 1970 from Harvard University, with a thesis on Orderings of Ultrafilters written under thesupervision of Frank Wattenberg.[1] Since 1970 he has been employed by the University of Michigan, first as a T.H.Hildebrandt Research Instructor (1970–72), then assistant professor (1972–76), associate professor (1976–84) andsince 1984 he has been a full professor there.In 2014, he became a Fellow of the American Mathematical Society.[2]

2.1 Selected publications and results

In 1984 Blass proved that the existence of a basis for every vector space is equivalent to the Axiom of Choice. Hemade important contributions in the development of the set theory of the reals and forcing.Blass was the first to point out connections between game semantics and linear logic.He has authored about 175 research articles in mathematical logic and theoretical computer science, including:

• Blass, Andreas (1984). “Existence of bases implies the axiom of choice”. Axiomatic set theory, Proc. AMS-IMS-SIAM Jt. Summer Res. Conf., Boulder/Colo. 1983, Contemp. Math. 31. pp. 31–34.

James Earl Baumgartner

James Earl Baumgartner (March 23, 1943 – December 28, 2011) was an American mathematician who workedin set theory, mathematical logic and foundations, and topology.[1]

Baumgartner was born in Wichita, Kansas, began his undergraduate study at the California Institute of Technology in1960, then transferred to the University of California, Berkeley, from which he received his PhD in 1970 from for adissertation entitled Results and Independence Proofs in Combinatorial Set Theory. His advisor was Robert Vaught.[2]He became a professor at Dartmouth College in 1969, and there spent his entire career.One of Baumgartner’s results is the consistency of the statement that any two ℵ1 -dense sets of reals are order iso-morphic (a set of reals is ℵ1 -dense if it has exactly ℵ1 points in every open interval). With András Hajnal he provedthe result (Baumgartner–Hajnal theorem) that the partition relation ω1 → (α)2n holds for α < ω1, n < ω . He diedof a heart attack in 2011.[3]

L. E. J. Brouwer

Luitzen Egbertus Jan Brouwer ForMemRS[3] (Dutch: [ˈlœyt̯sə(n) ɛɣˈbɛrtəs jɑn ˈbrʌu̯ər]; 27 February 1881 – 2December 1966), usually cited as L. E. J. Brouwer but known to his friends as Bertus, was a Dutch mathematicianand philosopher, a graduate of the University of Amsterdam, who worked in topology, set theory, measure theoryand complex analysis.[1][4][5] He was the founder of the mathematical philosophy of intuitionism.

8.1 Biography

Early in his career, Brouwer proved a number of theorems that were breakthroughs in the emerging field of topology.The most celebrated result was his proof of the topological invariance of dimension. Among his further results, theBrouwer fixed point theorem is also well known. Brouwer also proved the simplicial approximation theorem in thefoundations of algebraic topology, which justifies the reduction to combinatorial terms, after sufficient subdivision ofsimplicial complexes, of the treatment of general continuous mappings. In 1912, at age 31, he was elected a memberof the Royal Netherlands Academy of Arts and Sciences.[6]

Brouwer in effect founded themathematical philosophy of intuitionism as an opponent to the then-prevailing formalismof David Hilbert and his collaborators Paul Bernays, Wilhelm Ackermann, John von Neumann and others (cf.Kleene (1952), p. 46–59). As a variety of constructive mathematics, intuitionism is essentially a philosophy ofthe foundations of mathematics.[7] It is sometimes and rather simplistically characterized by saying that its adherentsrefuse to use the law of excluded middle in mathematical reasoning.Brouwer was a member of the Significs group. It formed part of the early history of semiotics—the study of symbols—around Victoria, Lady Welby in particular. The original meaning of his intuitionism probably can not be completelydisentangled from the intellectual milieu of that group.In 1905, at the age of 24, Brouwer expressed his philosophy of life in a short tract Life, Art andMysticism described byDavis as “drenched in romantic pessimism” (Davis (2002), p. 94). Arthur Schopenhauer had a formative influence onBrouwer, not least because he insisted that all concepts be fundamentally based on sense intuitions.[8][9][10] Brouwerthen “embarked on a self-righteous campaign to reconstruct mathematical practice from the ground up so as to satisfyhis philosophical convictions"; indeed his thesis advisor refused to accept his Chapter II " 'as it stands, ... all interwovenwith some kind of pessimism and mystical attitude to life which is not mathematics, nor has anything to do with thefoundations of mathematics’ " (Davis, p. 94 quoting van Stigt, p. 41). Nevertheless, in 1908:

"... Brouwer, in a paper entitled “The untrustworthiness of the principles of logic”, challenged the beliefthat the rules of the classical logic, which have come down to us essentially from Aristotle (384-−322B.C.) have an absolute validity, independent of the subject matter to which they are applied” (Kleene(1952), p. 46).

“After completing his dissertation (1907 - see Van Dalen), Brouwer made a conscious decision to temporarily keephis contentious ideas under wraps and to concentrate on demonstrating his mathematical prowess” (Davis (2000), p.95); by 1910 he had published a number of important papers, in particular the Fixed Point Theorem. Hilbert—theformalist with whom the intuitionist Brouwer would ultimately spend years in conflict—admired the young man andhelped him receive a regular academic appointment (1912) at the University of Amsterdam (Davis, p. 96). It wasthen that “Brouwer felt free to return to his revolutionary project which he was now calling intuitionism " (ibid).

8.2. BIBLIOGRAPHY 29

He was combative for a young man. He was involved in a very public and eventually demeaning controversy in thelater 1920s with Hilbert over editorial policy at Mathematische Annalen, at that time a leading learned journal. Hebecame relatively isolated; the development of intuitionism at its source was taken up by his student Arend Heyting.Dutch mathematician and historian of mathematics, Bartel Leendert van der Waerden attended lectures given byBrouwer in later years, and commented: “Even though his most important research contributions were in topology,Brouwer never gave courses in topology, but always on—and only on—the foundations of his intuitionism. It seemedthat he was no longer convinced of his results in topology because they were not correct from the point of view ofintuitionism, and he judged everything he had done before, his greatest output, false according to his philosophy.”[11]

About his last years, Davis (2002) remarks:

"...he felt more and more isolated, and spent his last years under the spell of 'totally unfounded financialworries and a paranoid fear of bankruptcy, persecution and illness.' He was killed in 1966 at the age of85, struck by a vehicle while crossing the street in front of his house.” (Davis, p. 100 quoting van Stigt.p. 110.)

Paul Bernays

Paul Isaac Bernays (17 October 1888 – 18 September 1977) was a Swiss mathematician, who made significantcontributions to mathematical logic, axiomatic set theory, and the philosophy of mathematics. He was an assistantand close collaborator of David Hilbert.

9.1 Biography

Bernays spent his childhood in Berlin, and attended the Köllner Gymnasium, 1895-1907. At the University of Berlin,he studied mathematics under Issai Schur, Edmund Landau, Ferdinand Georg Frobenius, and Friedrich Schottky;philosophy under Alois Riehl, Carl Stumpf and Ernst Cassirer; and physics under Max Planck. At the University ofGöttingen, he studied mathematics under David Hilbert, Edmund Landau, Hermann Weyl, and Felix Klein; physicsunder Voigt and Max Born; and philosophy under Leonard Nelson.In 1912, the University of Berlin awarded him a Ph.D. in mathematics, for a thesis, supervised by Landau, on the ana-lytic number theory of binary quadratic forms. That same year, the University of Zurich awarded him the Habilitationfor a thesis on complex analysis and Picard’s theorem. The examiner was Ernst Zermelo. Bernays was Privatdozentat the University of Zurich, 1912–17, where he came to know George Pólya.Starting in 1917, DavidHilbert employed Bernays to assist himwith his investigations of the foundations of arithmetic.Bernays also lectured on other areas of mathematics at the University of Göttingen. In 1918, that university awardedhim a second Habilitation, for a thesis on the axiomatics of the propositional calculus of Principia Mathematica.[1]

In 1922, Göttingen appointed Bernays extraordinary professor without tenure. His most successful student there wasGerhard Gentzen. In 1933, he was dismissed from this post because of his Jewish ancestry. After working privatelyfor Hilbert for six months, Bernays and his family moved to Switzerland, whose nationality he had inherited fromhis father, and where the ETH employed him on occasion. He also visited the University of Pennsylvania and was avisiting scholar at the Institute for Advanced Study in 1935-36 and again in 1959-60.[2]

9.2 Mathematical work

Bernays’s collaboration with Hilbert culminated in the two volume work Grundlagen der Mathematik by Hilbert andBernays (1934, 1939), discussed in Sieg and Ravaglia (2005). In seven papers, published between 1937 and 1954 inthe Journal of Symbolic Logic, republished in (Müller 1976), Bernays set out an axiomatic set theory whose startingpoint was a related theory John von Neumann had set out in the 1920s. Von Neumann’s theory took the notion offunction as primitive; Bernays recast Von Neumann’s theory so that sets and proper classes were primitive. Bernays’stheory, with some modifications by Kurt Gödel, is now known as the Von Neumann–Bernays–Gödel set theory. Aproof from theGrundlagen der Mathematik that a sufficiently strong consistent theory cannot contain its own referencefunctor is now known as the Hilbert–Bernays paradox.

Tomek Bartoszyński

Tomek Bartoszyński (born May 16, 1957 in Warsaw) is a Polish-American mathematician who works in set theory.He is the son of statistician Robert Bartoszyński.

11.1 Biography

Bartoszyński studied mathematics at the University of Warsaw from 1976 to 1981, and worked there from 1981 to1987. In 1984 he defended his Ph.D. thesis Combinatorial aspects of measure and category; his advisor was WojciechGuzicki.[1] In 2004 he received his habilitation from the Polish Academy of Sciences.From 1986 on he worked in the United States: he taught at University of California in Berkeley and Davis. From 1990to 2006 he was professor (full professor from 1998 on) at Boise State University. In 1990/91 he visited the HebrewUniversity of Jerusalem as a fellow of the Lady Davis foundation, and in 1996/97 he visited the Free University ofBerlin as a Humboldt fellow.Currently he is one of the program directors at the National Science Foundation (NSF), responsible for Combinatorics,Foundations, and Probability.His wife Joanna Kania-Bartoszyńska is the NSF program director for topology and geometric analysis.

11.2 Scientific work

Bartoszyński’s work is mainly concerned with forcing, specifically with applications of forcing to the set theory ofthe real line. He has written about 50 papers in this field, as well as a monograph:
