  • I. Groundings (the development of the information understanding)0. Towards a general understanding of information1. Development of the information concept: Plato, Aristotle, Middle Ages, Modernity, (technique and physics)2. General understanding of Information3. Mathematical Theory of Communication4. Algorithmic Theory of Information5. Information in the sciencesSS 2012 A General Understanding of Information 7
  • 0. Towards a General Understanding of Information In the Information Era we should be able to understand what really information means (Comparison to the Iron Era, iron vs cupper) The Nature of information is not solved Information can be considered as something mediating between Objects and Subjects To this end, a general understanding of O. & S. is also needed.SS 2012 A General Understanding of Information 8
  • I.0 Information concept (tangible) Information Time t1 t2 t3 Object: In opposition to the Subject Subject of the change of the changeSS 2012 A General Understanding of Information 9
  • (0) Information concept (immaterial) Time Information t1 t2 t3 Object: In opposition to the subject of Subject of the change the change (awareness) (in the awareness)SS 2012 A General Understanding of Information 10
  • (0) Clarifying Form: a particular configuration/Gestalt produced in the subject. Subject: System which can adopt potential changes Object: what remains stable (in front of the subject) causing the changes in the subject ~ Model Time: Run of the procedure (i.e. change of the subject) O. vs S.: In strict sense, both sides change during the process (O. & S. are only relative regarding the corresponding change)SS 2012 A General Understanding of Information 11
  • (1) Evolution of the information concept (a) Plato vs. AristotlePlato (idealistic tradition) Form is what exists in the first place and it is out of the world, otherworldliness (a-spatial, a-temporal). Forms are participated by appearances (phenomena) and souls. By these means the observer can really recognize the forms. The innate ideas must be awaken (the observer recognizes what already was in his soul). The observer returns to the truth, slept within himself.SS 2012 A General Understanding of Information 12
  • Plato: World of forms Form Appearance I Ideas Observer Decontextualizing: Die existing Forms belong to the otherworldliness (a- spatial, a-temporal)SS 2012 A General Understanding of Information 13
  • Plato and Signal Theory From the viewpoint of the modern signal theory (Digital Transmission): Ideal of transparence Si Si Compared with Si {S1, S2, SN} {S1, S2, SN} NoiseSS 2012 A General Understanding of Information 14
  • (b) Aristotle Form: embrace the essential properties of a thing Matter: embrace the potential changes Every thing has its own form, its own essence, which correspond to its being. The reality of a thing relates to its details, its differences (dish in Plato and Aristotle) There is a general being, which corresponds to the being of the species. One can inductively recognize them by observation.SS 2012 A General Understanding of Information 15
  • (c) Information concept (Middle ages)Augustine of Hippona: Credo ut intellego Truth Revelation Requirement: God Noiseless Belief channelsAnselm: Fidens quarens intellectum endeavor towards understandingAquinas: Reality is understandableHermeneutic: Activity of Interpretation, Imagination-AbilitySS 2012 A General Understanding of Information 16
  • (d) Information concept (Modernity) Reformation and Enlightenment received significantly the clarity and transparence of Augustine (transparency unmediated, No distance) Physics in that time had control over space, but not over time -until 19.Century-. Newton: Absolute, true, and mathematical time, of itself, and from its own nature, flows equably without relation to anything external. (Scholia to the definitions in PN-Principia Mathematica, Bk. 1, 1689) Time was left free to philosophy, where it was not considered as an independent concept, but as something inherent to processes (Leibniz, Kant, Heidegger, Bergson).SS 2012 A General Understanding of Information 17
  • (e) Modern Communication theory The most important difference between early and modern telecommunication concerns transmission speed. Until end of the 19th c. I-transmission was understood as an immediate event: The time of the transmission process disappears. The mediating space correspondingly disappears, One can only speak of the process of the E. and R., which must be synchronized.SS 2012 A General Understanding of Information 18
  • XIX C. Physics Late 19th Century Physics (e.g. Maxwell) understood the being of time as attached to processes: Entropy represents the irreversibility of processes (Time: inevitable and unidirectional run of the processes) Physics of fields understood Processes in Space & Time > Change in the understanding of EM transmissionSS 2012 A General Understanding of Information 19
  • Mathematical Theory of Communication (Shannon) Original Decoded message Codified message Message Emitter Coder Channel Decoder Receptor Noise Noiseless Channels (magische Kanale)This viewpoint (and alongside the oblivion of space) have many consequences inthe actual game of the globalization:1. It technically enables the run of the economical processes at the international level.2. It technically enables the hiding of power relations.3. Instead of facilitating social achievements, the power constellation (economical domination) can easily reconfigure the network of economic agency.SS 2012 A General Understanding of Information 20

  • Aspects of a general understanding of information Semiotic: Theory of signs and symbols (Morris, 1938) The Syntax concerns the occurrence of individual information units and their mutual relations. The Semantic concerns the meaning of information units and their mutual relations. The Pragmatic concerns the effect of information units and their mutual relations.A complete understanding of information unfolds in thedimensions: Syntax, Semantic and PragmaticSS 2012 A General Understanding of Information 22
  • I.2. Aspects of a general understanding of information Timely aspects of information (Weizscker): Actual: already present and effected information Potential: the possibility to obtain actual information.Namely, the difference between past and future is grasped bythe information concept.Actual information exists factually, whereas potentialinformation exist only in relation to possibilities.Therefore AI can be regarded ontologically, whereas PI isintrinsically relational.SS 2012 A General Understanding of Information 23
  • I.2(a) Syntax and Probability I = - ld p = - log2 p Extensive measure: I-Content of a dual system: I(cont) = I(1) + I(2) Probability & potential syntactic information are equivalent concepts for the quantification of possibilities. The concept of probability can be regarded as a sub-concept of a general information concept.SS 2012 A General Understanding of Information 24
  • (I.2.a) Example: information measurement through unveiling a card 32 Cards: 8 cards / type (clubs, spades, hearts and diamonds) 1-8 Clubs 1-8 Spades 1-8 Hearts 1-8 Diamonds Mnimal # of questions in average- for yes/no answers Q1: Black? A1: No Q2: Heart ? A2: No Q3: > 4? A3: No Q4: > 2? A4: Yes Q5: 4? A5: Yes SS 2012 A General Understanding of Information 25
  • I.2(b) Semantic and Pragmatic The necessary entanglement of semantic and pragmatic aspects of information within semantic-pragmatics offers the possibility to an objectification of semantics. Context always presuppose context, I. always presuppose I. Information exist only relative in respect to a difference between 2 semantic levels. The philosophical key issues in the research of the I- concept concern the epistemological and ontological aspects. Both questions are actually interdependent.SS 2012 A General Understanding of Information 26
  • I.3. Telecommunication Information theory Shannons Information-Entropy Ii=- log2pi P={1/2, 1/4, 1/8, 1/8 }; Dice p1=p; p2=(1-p) Theory of codification In order to transmit the maximal amount of information content in the minimal time: Redundancy-free Source (Morse, 4 symbols ex.) Huffman method: lk~Ik, Prefix-feature SS 2012 A General Understanding of Information 27
  • I.3. Telecommunication Information theory Firstness (Erstmligkeit) and Confirmation The word information, in this theory, is used in a special sense that must not be confused with its ordinary usage. In particular, information must not be confused with meaning In fact, two messages, one of which is heavily loaded with meaning and the other of which is pure nonsense, can be exactly equivalent, from the present viewpoint, as regards information... In the theory of communication, information relates no so much to what is said but to what could be said. information is a measure of the freedom of choice communicators have when they select a message. (Weaver) The telecommunication I-Theory treats Information under syntactical aspectsSS 2012 A General Understanding of Information 28
  • I.3 Telecommunication Information theoryIs there information without confirmation? Phenomenon, manifestation underlying reality Perception, stating that something is the case requires confirmation A confirmed phenomenon provides no information Information Shannon (MTC) Pragmatic-semantics 0 1/2 1 Confirmation (Redundancy) 1 0 Firstness (Novelty)SS 2012 A General Understanding of Information 29
  • I.4. Semantical approach to InformationGDI (data + meaning) is an instance of information (understood as semantic information) if and only if 1) consists of n data, for n1 2) The data are well formed 3) The wellformed data are meaningfulDd datum X being distinct from y, where x and y are 2 uninterpreted variables and the relation of being distinct as well as the domain are left open to further interpretation.SS 2012 A General Understanding of Information 30
  • I.4. Semantic approach to InformationEnvironmental information 2 systems a & b coupled in such a way that as being F is correlated to b being G, then carrying the information for the observer of a the Information that b is G.Factual semantic information p qualifies as factual semantic information if and only if p is (constituited by) well-formed, meaningful and veridical dataSS 2012 A General Understanding of Information 31
  • I.4. Algorithmic Information Theory The algorithmic information content is a measure of the syntactical diversity or complexity The very shortest description: Ialg(s)=L(pmin s) Differences with the shannonian concept: 1. Syntactic vs. Minimal complexity as usage of that semantic providing a minimal syntactic effort. 2. Potential vs. Actual Information 3. Objective vs. Relative quantitative concept: Complexity in relation to regularities that are readable from a selected semantic space. The algorithmic I-content measures actual I. under both syntactic and semantic aspects. It represents no absolute quantity but a relative one. It is not computable, i.e. it is related to subjects.SS 2012 A General Understanding of Information 32
