Philosophy of Time
Framing conjecture: two cultures split?
C.P. Snow: “Literary intellectuals and physical
scientists with a lack of understanding and attitudes
so different that they cannot find common ground”
Non-scientists think that scientists are shallowly optimistic
and scientists think that literary intellectuals lack foresight
Oliver Sacks: Deep insights about human nature
come first to poets and artists, to be systematically
explored by scientists only decades or centuries later
Horace: Ut pictura poesis, as is painting so is poetry;
as is art so is science (not favorizing one mode)
Science: vaunted, arts: everyone has an experience

Philosophy of Time
Bergson: clock time and felt time (duration)
Two time regimes
1. Objective (quantitative): Measurable
clock time
2. Subjective (qualitative): Internal
experience of lived time (flying by,
taking forever, flow state); duration
The intensity of the lived experience
of time produces memory,
consciousness, self
Exercise of free will is possible, by
tuning into the internal qualitative
experience of time duration and
spontaneity, and acting from there

Hume: bundles of unconnected perceptions
Humean verification problem: mountain–teacup–mountain
Kant: there must be a meta-apparatus, an “I think”
(consciousness) that collects individual sense
impressions and recognizes them as the same object
(Transcendental Unity of Apperception)

11. 24 Jan 2020
Philosophy of Time
Kant: two-stem theory of knowing
The “I think” (consciousness) connects the faculties
of Sensibility and Understanding
The two stems of knowing must operate together since
“without sensibility no object is given, and without
understanding no object is thought”
This is why “thoughts without content are empty, and
intuitions without concepts are blind” (A51/B75, 193-4)
Problem of time arises: integrating divergent
temporalities of snapshot and eternality

How does knowing work?
Kant: determinate vs. reflective judgment
Sensibility and understanding operate together to
make a judgment (judging is an exercise of freedom by
grasping something in the world to have meaning)

Determinate judgment
Routine subsuming of
particulars under a

Reflective (aesthetic) judgment
The encounter with the artwork (or
the unknown), a new particular
upon which we must reflect and
derive a new concept

Kantian neuroscience: study supports theory
Being told that an image is an artwork down-regulates
(subdues) emotional response
Tendency to “distance” ourselves from the image

Philosophy of Time
Kant: retentional time structure
The problem of time forces Kant to specify the
third faculty of the imagination to join the two
stems of knowing (sensibility and understanding)
The reproductive imagination runs through and gathers
together sense perceptions (A102)
Introduces retentional time structure (“while” loop)
Sense perception (immediate snapshot), “while” loop
remembers previous perceptions (mediate perdurance),
to subsume under a concept (eternal)

Definition
Aesthetic theory of felt knowledge is…
The feeling tone that knowledge is true
The right answer to a problem clicks into place
Mathematician break-throughs: ease, elegance
Occam’s Razor: the simplest solution is correct
There is a special quality to truth
Claim: an emotionally-installed understanding is a
superior form of intellectual understanding
There is an aesthetic aspect and a cognitive aspect to the
right answer of felt knowledge, as an indication of emotion
and intellect working together
30
All that we call invention, discovery in the highest sense
of the word, is the meaningful application and the
putting into practice of a very original feeling of truth.

Poetry (poetic language) and praxis (practical manual)
Singular work because captures both the heart and the
intellect through the imagination, Melville:
(May 1, 1850): The whaling voyage is a strange sort of a book;
blubber is blubber tho’ you may get oil out of it, the poetry runs
as hard as sap from a frozen maple tree
(June 27, 1850): The book is a romance of adventure, founded
upon wild legends in the Southern Sperm Whale Fisheries

Moby-Dick: Problem of Representation
32
Previous representation only provided by myth
Though elephants have stood for their full-lengths, the
living Leviathan has never yet floated for his portrait
The living whale, in his full majesty, is only seen at sea in
unfathomable waters; the vast bulk of him out of sight
The only way to derive a tolerable idea of his living contour
is by going a whaling yourself

Relation of form and content
Winkelmann: focus on content
Lessing: at least 50% is form
Adorno: “art…is simply identical with form”
Art is a way of creating and expressing the
element of truth in a culture – Heidegger
Art is pressing a representation of individual and
collective self-concept into materials – Hegel
Examples: pyramids, Parthenon, skyscrapers,
sculpture, snow forts
What art seeks to disturb is monotony of type,
slavery of custom, tyranny of habit, and the
reduction of man to the level of a machine -

Aesthetics: What counts as a Work of Art?
Venue: if displayed in a gallery, it is art
Adorno: An artwork has its own law of
form (a relation between its formal
elements; a principle of self-legislation
(freedom), vs. externally-imposed rules)
The autonomous artwork produces meaning
out of itself (by acting as a free subject)
Deleuze: The artist has an encounter
with originary time
The artwork is “a transmutation of
substance” giving the viewer access to
“an original world”

Philosophy of Time
Positions
1. Time and space are fundamental
Time and space exist as concrete and basic
“furniture” of reality that cannot be derived from
other entities or structures
2. Time and space are emergent
Time and space exist, not fundamentally but as
derived from other entities or structures (i.e.
quantum matter and its relations)
What precedes? Geometry (domain in which things
behave) or Dynamics (parameters of behavior)

Conclusion
At the smallest scale of reality (Planck
scale) and in general at small scales, the
focus is on time as an emergent feature
At the macro scale of philosophy,
aesthetics, and applied science, the
focus is on integrating snapshot and
perdurant temporal regimes
Expected: the smallest scales of reality are
still under physical investigation
