What you should get out of this
This is an experimental lecture It’s a superficial overview of semantics The goal is to
Motivate some of the programming and art theory that is to come
Get you to see meaning as being a very complicated (and interesting) phenomenon
I will not test you on it Although subsequent lectures will go over some of this
stuff in more detail, and then it will be fair game
A simple model
There are thoughts in the speaker’s head They are represented in language They are reproduced in the hearer’s head
“all lifeis suffering”
Form and content
Form is the concrete manifestation of the message (sound/object/pattern)
Content is the object referred to (denoted by) the message
“Buddha”
notation denotation(sort of)
A more detailed model
Speaker encodes meanings as messages Listener decodes messages to recover the meaning Encoding and decoding processes are perfect inverses
“Buddha”encode decode
Speaker Listener
Syntax and semantics
Forms have structure Sentences are made of phrases
Phrases are made of words Words are made of syllables
Syllables are made of phonemes Images are made of lines and forms
Lines and forms are made of points
The structure of the form is its syntax
Example: “I walked to the lake” can be read as Noun phrase: “I” Verb phrase: “walked to the lake”, which can be broken up as:
Verb: “walked” Prepositional phrase: “to the lake”, which could be broken up further if I weren’t running
out of room on this slide
Syntax and semantics
Meanings also have structure (This one’s way more subtle because philosophers can’t even
agree on whether meanings really exist) By many theories, meanings are “made of”
Objects being referred to in the world Properties being ascribed to them Relations being claimed to hold between them
Example: the meaning of “water is wet” can be decomposed into: An object: water A property ascribed to it: wetness
Syntax and semantics
And now the important part: The structure of form and content (roughly) mirror one another So the encoding/decoding process can be (roughly) described in
terms of the structures of form and content These rules for encoding/decoding are called the semantics of
the forms
Example: “water is wet” ascribes wetness to water More generally, sentences of the form “noun is adjective” are
decoded by Finding the meaning of the noun (an object) Finding the meaning of the adjective (a property) Ascribing the property to the object
Visual semantics
Visual decoding follows some basic rules of thumb: Closed contours
describe objects Occlusion signals
depth ordering
Generativity
Language is generative It has a relatively small set of words
(400-50,000 depending on language and speaker) It has a relatively small number of rules for combining
them Every sentence has a subject and a predicate Every predicate has a verb and arguments Etc.
These combine to create an infinite number of sentences
With an infinite number of possible meanings
A more accurate model
In practice, the decoding process does not produce an exact copy of the meaning in the listener’s head
In fact, it usually produces many meanings Many of which may be completely unintended or “wrong”
“all lifeis suffering”
Denotation and connotation
The denotation (aka referent, extension) of a term is the object(s) it refers to in the world
But extension is not a good model of meaning The following phrases have all been used in public discourse to refer to
the same person “Our commander and chief” “The president” “The stupid one”
(spoken by a French journalist when the election results were announced) In their use-contexts, they all have the same extension But they are not equivalent
The connotation (intension) of a term is, well …, the rest of its meaning
This is where math stops
In math and (almost all) formal logic, the meaning of expressions defined by their extension “5” and “4+1” are completely interchangeable No intension
Most Anglo-American philosophy also focuses on extensional semantics, rather than intention Extension can be defined rigorously
And systematized And theorized with good predictive power
Intension’s open-endedness makes it very hard to theorize
This is where computers stop
Computer science also uses extensional semantics because It grew out of math and logic Extensional semantics can be systematized
Also because You don’t want your word processor exercising poetic
license with your term paper We can’t (presently) make computers understand
connotation even when we try
Meaning in continental philosophy:Semiotics/semiology
Meaning is communicated through signification A sound or image refers to/suggests/signifies
a set of ideas or meanings
Signs as units of language Signifier
Material manifestation Image/sound/object
Signified Meaning/idea
“Weaker” theory than analytic philosophy (I.e. fewer predictions) But consequently a much broader domain of application Including connotation
Sign
Signifier
Signified
Barthes:Connotation as second-order signification
Connotation is communicated through association
As complete sign is used in a meta-sign to signify another idea
Myths Pervasive, “mythic” values and
beliefs used by a society to understand itself and the world
Idealized fictions (for him at least) Operate at the level of
connotation

Connotation über alles
“Kerry”, that sounds French, doesn’t it?- Unnamed Whitehouse source, Fall 2002
In practice, denotation is often irrelevant Much political and ethical discourse operates almost
entirely at the level of connotation Most people don’t even know the lyrics to their
favorite songs
In case you didn’t believe me
I am he as you are he as you are me and we are all together.See how they run like pigs from a gun, see how they fly.I'm crying.
Sitting on a cornflake, waiting for the van to come.Corporation tee-shirt, stupid bloody Tuesday.Man, you been a naughty boy, you let your face grow long.I am the eggman, they are the eggmen.I am the walrus, goo goo goo joob
- Lennon and McCartney, I am the Walrus (UK, 1966)

The PoliceWith Every Breath You Take (UK, 1983)
Every breath you take and every move you make
Every bond you break, every step you take
I'll be watchin' you
Every single day and every word you say
Every game you play, every night you stay
I'll be watchin' you
Signs have (partial) autonomy
People never completely work out their intended meaning before they speak
People use signifiers without fully understanding their consensual meanings
People interpret signifiers differently The consensual meanings of signifiers change
over time
Appropriation
Signs can also be appropriated by third parties and retasked for new meanings Quotation Warhol and Cornell’s

A3, Woke Up This Morning (UK, 1997)
Woke up this morningGot yourself a gun,Your mama always said you’d beThe Chosen One.
She said: You’re One in a millionYou’ve got to burn to shine,But you were born under a bad sign,With a blue moon in your eyes.
Woke up this morningAll that love had gone,Your Papa never told youAbout right and wrong.
But you’re looking good, baby,I believe that you’re a feeling fine, shame about it,Born under a bad signWith a blue moon in your eyes.
Bobby McFerrinDon’t Worry, Be Happy (USA, 1988)
Here's a little song I wroteYou might want to sing it note for noteDon't worry, be happyIn every life we have some troubleBut when you worry
you make it doubleDon't worry, be happyDon't worry, be happy now
Don't worry, be happy Don't worry,be happy
Don't worry, be happy Don't worry,be happy
Ain't got no place to lay your headSomebody came and took your bedDon't worry, be happyThe landlord say your rent is lateHe may have to litigateDon't worry, be happyDon't worry, be happy
Don't worry, be happy, Don't worry, be happy
Don't worry, be happy, Don't worry, be happy
A less detailed model
All communication takes place in the context of culture Culture constantly shifts the meanings of its signifiers
As a result of ongoing discourse over the meanings of signifiers
“Buddha”
How to do things with words
We don’t just communicate to exchange information J.L. Austin, How to do things with words, 1960
Communication is a form of action Requesting assistance Ordering subordinates Promising future action Persuading others to thought or action
Seeing an object or concept in a new light Seeing connections not previously seen … without ever actually stating the new thought
Communication as action
The speaker seeks to change the listener’s mind The speaker chooses words to effect that change The listener is changed
“this mind isnot Buddha”
Patti Smith: Dancing Barefoot
she is benedictionshe is addicted to theeshe is the root connection she is connecting with he
here I go and I don't know why I fell so ceaselessly could it be he's taking over me...
I'm dancing barefoot heading for a spin some strange music draws me in makes me come on like some heroin/e
she is sublimation she is the essence of thee she is concentrating on he, who is chosen by she
here I go and I don't know why I spin so ceaselessly,could it be he's taking over me…
I'm dancing barefoot heading for a spin some strange music draws me in makes me come on like some heroin/e
Communication as social action
Neil Young - Ohio
Tin soldiers and nixon coming,We’re finally on our own.This summer I hear the drumming,Four dead in ohio.
Gotta get down to itSoldiers are gunning us downShould have been done long ago.What if you knew herAnd found her dead on the groundHow can you run when you know?
Art and communication
Art is communication Your goal is to learn to
Understand the role of signs in our culture The dominant sign systems that organize our thinking The “ecology” of signs
Learn to do good encoding Understand the decoding process Become a good listener to your own decoding process
Computers and communication
Programming is also communication From programmer to computer From programmer to programmer
Your goal is to learn to understand The syntax of programs
Recognize gibberish The semantics of programs
Given a desired computation, understand how to formulate a program to do it
Given a program, understand how to determine what it’s doing
