The Specious Present

‘the short duration of which we are immediately and incessantly sensible’

James

Page 2: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Time Consciousness

SpeciousPresent

= time as it most directly and distinctively manifests in

experience

Page 3: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

BUT: speciouspresent: particularly

controversial (& baffling)

Does it really exist?

Isn’t itparadoxical?

Page 4: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

My aims:

• Survey the main options + comment on James’ position

• Isolate some key assumptions motivating the different positions

• Defend a neo-Jamesian conception • Counter some recent criticisms of Sean Kelly’s• Explore a few implications

Page 5: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Specious Present: why believe?

Primary reason: to make sense of our experience

Page 6: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

“change itself is one of the things immediately experienced.” (James,WPE)

• Some changes = too slow to be perceived (growth of oak tree).

• Some are too fast (speeding bullet).

• Some are just right: we directly apprehend them.

Page 7: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Seeing motion:

Page 8: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Enter SP: ‘all the changes in place of a meteor seem … to be contained in the present.’ (Clay)

So: our direct perceptual awareness can’t be confined to a durationless instant

1 sec

Page 9: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Further data: ‘phenomenal depth’

Strictly durationless tone = hard to conceive

Most simple sensations have some temporal depth

Page 10: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

More generally: (typical) streams

of consciousness are continuous

each phase is experienced as

giving way to the next

Page 11: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

A puzzle about length: ‘a core of about a

dozen seconds, up to a minute’ (James)

We’re not directlyaware of what we

experienced a minute ago

Or even a few seconds!

Page 12: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

(Partially) plausible diagnosis:

SP proper (e.g. 1sec)

Vivid short-term memories

Vivid anticipations

James: ‘the practically cognized present is no knife-edge, but a saddleback’

Page 13: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Making sense of SP: two main models

• Retentionalist– immediate experience

of change occurs in a single moment

– specious present does not really extend through time

• Extensionalist– immediate experience

of change is not confined to a single moment

– specious present is spread through time

Page 14: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Extensionalism: 1 SP

James: Retentionalist or Extentionalist??

Page 20: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Sean Kelly (recent recommendation):

• ‘Specious present’ = what James was committed to

• James = Extensionalist

• So: distinguish ‘specious present’ theories from Retentionalist approaches

Page 21: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

James = Extensionalist?

‘duration-blocks’ stream doctrine

Page 22: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

James’ Stream doctrineexperiences

not unified(empiricism)

experiences unified by

soul-substance(rationalism)

REJECT

Experience unifies itself, synchronically & diachronically

via ‘conjunctive relations’

Page 23: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Conjunctive relations:• ‘The conjunctive relation that has given

most trouble to philosophy is the co-conscious transition, so to call it, by which one experience passes into another when both belong to the same self. … this sense of continuity in that most intimate of all conjunctive relations’ (WPE)

Page 24: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

But: James = Retentionalist!

‘The knowledge of some other part of the stream, past or future, near or remote, is always mixed in with knowledge of the present thing’

Volkmann has expressed the matter admirably: ‘if A and B are to be represented as occurring in succession they must be simultaneously represented’

Page 25: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

James’ SP diagram: pure Retentionalism!

Page 26: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Diagnosis:

• In Principles James is pulled in different directions:– Retentionalist when in scientific mode– Extentionalist when in

phenomenological/philosophical mode

Page 27: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Terminological Recommendation:

• ‘Specious Present’ – for any account which attributes apparent temporal depth to experience– E.g. Retentionalism– E.g. Extensionalism

Page 28: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Retentionalism: main advocates

Husserl

James(/2)

Brentano

Ward

Broad (L)

Dobbs

Kant

Lockwood

Page 29: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Retentionalism: motivation (i)

• Can we really be directly aware of what lies in the past? (Or the future?) Or is clairvoyance commonplace?

awareness Avoid!

Past Present Future

Page 30: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Retentionalism: motivation (ii)

Simultaneous Unity Thesis (SUT): to be apprehended as successive, contents must be presented

together in consciousness at the same moment

– regarded as axiomatic by Volkmann, Ward, James, Husserl, Dobbs

Page 31: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Why aren’t these experienced as a chord,

rather than a succession?

Page 33: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Main solutions:Broad’s

‘presentedness’Dobbs’ ‘gravitas’

unclear

Husserl’s retentions

implausible

No matter: it still may be possible for momentary experience to have apparent temporal depth

Page 34: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Objection 2: phenomenologically dubious

Are we really aware, at each moment, of a temporal spread

of content?

I’m only aware of what’s

happening now!

Objection 3: expensive and exotic

Multiplies total quantity of experience in universe

Overlap Model: basic ingredients

= Jamesian duration block

Parts spread across time AND experienced together as a succession

single specious present

Page 44: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Diachronic co-consciousness = directly experienced succession/persistence

Doesn’t mean: hearing A and simultaneously hearing B (i.e.before it has occurred!)

A B A B

Does mean: directly hearing A-being-followed-by-B

Page 45: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Diachronic co-consciousness:

In consciousness together, but as a succession (not simultaneously = retentional model)

Page 46: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Overlap model: from blocks to streams

Stream of consciousness

Page 47: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Overlap: no (unwanted) duplications

Overlapping SPs possess common parts (D in SP1 = D in SP2, etc)

Page 48: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

What explains the apparent direction of experience?

• The asymmetric character of diachronic co-consciousness relationship?

• The intrinsic character of phenomenal contents?

More economical option

Page 49: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Duration-blocks inherently dynamic:

motion! motion!

Overlap but no ‘temporal modes’ (= austere)

Jamesian saddleback

‘qualities’/intrinsic properties

“we have a constant feeling sui generis of pastness, to which every one of our experiences falls prey” James

Extension/Overlap v. Retentionalism

KEY ISSUE

Simultaneous UnityThesis

Page 58: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Accepting Overlap = rejecting SUT

C D

Non-simultaneous

But unified: experienced together

Page 59: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Why accept SUT?

James: accommodate Kantian insight A metaphysical

assumption

A certain conception of time

Page 60: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

James: ‘A succession of feelings, in and of itself, is not a feeling of succession’

True! But:

C D E C D E

CDE

Difference can be explained in Extensional way also…

Diachronic co-consciousness

Page 61: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

2nd Motivation: a Neo-Rationalist Assumption?

• Eg: unity of consciousness requires something SIMPLE (non-extended, part-free)

- so a temporal spread of content must be unified by a non-extended experiencing

• Question: why believe this?

Page 65: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Why SUT?

Tacit commitment to presentism?

3nd motivation

Page 66: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

If reality is like this:

then Extensionalism can’t be true

time

No past No future

Page 67: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Obvious observation:

• 19th century: Presentism (probably) very common

• 21st century: less common (among philosophers)

• 4-d world-view more prevalent

Page 68: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

4-d perspective: extension through (space)time = unproblematic

4-d hunk of wood (perduring)

4-d stream of experience

Page 69: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

So:

• SUT: less than wholly compelling

• Hence: overlap theory remains a live option– maybe the better option (assuming we want a

SP at all)

Page 70: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Sean Kelly’s (main) objectionsto Extensionalism?

Page 71: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

1. ‘how can we be aware of what’s no longer

happening?

No: only a diachronic co-consciousness relation

2. Can’t explain howsuccessive

3. Can’t explain perceived change

Yes it can: viaanimated contents

motion! motion!

Page 74: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Overlap Theory: implications

Page 75: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

An argument (sketch) for dualism:

• There is no temporal passage in the physical world (McTaggart, relativity, etc.)

• There is temporal passage in experience.

• So: experience is non-physical.

Page 76: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

But: Overlap Theory looks to be compatible with 4-d cosmology

Page 77: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

2 explanations for limited span of SP:

non-existence of past & future

short-span of diachronic

co-consciousness

looks compatible with 4-d worldview

Page 78: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

But what about flow? Doesn’t experience have a felt direction?

Yes but: phenomenal flow = intrinsic feature of experience

Doesn’t require ‘universal becoming/annihilation’

No more (or less) a problem for materialism than phenomenal colour

Page 79: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Objection: accounts of SP should be metaphysically neutral.

Retentionalism = compatible with all conceptions of time

Overlap Theory isn’t.

Page 81: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

But:

• Why must SP-theories be metaphysically neutral?

• Mightn’t SP provide empirical evidence for the nature of time in our universe?

• Why shouldn’t SP offer some clues as to the nature of time?

Page 82: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Illustration:

• Julian Barbour• Quantum Gravity• Wheeler-De Witt

equation• Universe = collection

of 3-d slices existing in phase space/platonia

• Our experience is confined to momentary ‘time capsules’

• Temporal unity of world = illusion

Page 83: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Platonia/Phase Space

‘Time Capsules’ = specious presents

Page 84: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

However:

• If consciousness = physical

• Overlap theory refutes Barbour’s speculation

Streams of experience bridge universe-phases

Page 85: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Platonia/Phase Space

If dualism: unified streams sustained by disunified world-phases - maybe possible?

stream of consciousness

Page 86: The Specious Present ‘the short duration of which we are immediately and incessantly sensible’ James.

Final speculation:

Specious Present as a guide to the cosmos: a Jamesian Universe?
