Meaning (n.) is what a paper crown on the white king lacks, however much it means to its owner: as long as it doesn't alter the use of the piece, it has no meaning.
Meaning (n.) is not a thing the word stands for; ask instead what an explanation of meaning looks like, and the hunt for an object called 'the meaning' dissolves.
Meaning (n.) what we say is hardly ever a conscious process running alongside the words — the rare exception is the actor's 'aside' on the stage.
Meaning (n.) is characterized by the use we make of a phrase, not a mental accompaniment, so 'I'm sure I mean something by it' justifies nothing.
Philosophy (n.) is difficult as a jigsaw is, where all the pieces are there and only mixed up, and force will not fit them: look at them carefully and arrange them.
Philosophy (n.) can never reduce anything to anything, or explain anything; it really is purely descriptive.
Philosophy (n.) has one difficulty above all: to say no more than we know.
Philosophy (n.) faces a muddle felt as a problem, not a scientific question waiting on a causal explanation of curious effects.
A Solipsism (n.) resembles a man redrawing county lines to say the real Devonshire is here; he wants a new notation.
Solipsism (n.) wants to say 'I am the vessel of life' — and it is essential that no one to whom I say it can understand me: not false, but meaningless, that he should.
Solipsism (n.) is the temptation to say only my experience is real — and the shame of saying it to anyone, who will reply he could say exactly the same.
Solipsism (n.) points ahead and says 'this is what's really seen', pointing to nothing as opposed to anything, like pressing the dashboard to push the car from inside.
Thinking (n.) about a fire that isn't burning is like looking for a thief who doesn't exist: I can't hang him, but I can look for him.
Thinking (n.) what is not the case puzzles us — 'how can one?' — though nothing is easier; the trouble comes from looking at the facts through a misleading form of expression.
Thinking (n.) as an experience may be just the experience of saying, or that experience plus others which accompany it.
Thinking (n.) is essentially the activity of operating with signs — done by the hand when we write, by mouth and larynx when we speak.
Mind (n.) is the queer medium we invent to house the 'organic' half of language — understanding, meaning, thinking — believing it can do what no material mechanism could.
The Mind (n.) seems to be what feels pain only because the 'I' in 'I have pains' denotes no particular body: no description of a body can replace it.
The Mind (n.) is said to think only by metaphor: an agent in a different sense from the sense in which the hand writes.
The Mind (n.) seems to work a miracle in a mental act, holding the whole calculus of language present, all in a lump, behind a single sentence.
Thought (n.) puzzles us less if we substitute for it the expression of the thought: Wittgenstein's rule of thumb.
Thought (n.) is not hiding behind the brain a man watches in a mirror: brain and words are two correlated 'expressions of thought', and 'where is the thought itself?' is nonsense.
Thought (n.) sought for a place, because sentences are somewhere, is like hunting the chess king the rules speak of among the wooden kings of the sets.
Thought (n.) belongs, if a place must be named, on the paper we write on or in the mouth that speaks, and the head or the brain is a locality only in another sense.
Metaphysics (n.) puts an unclarity about the grammar of words into the form of a scientific question.
Metaphysics (n.) hides in sentences like 'I can't feel his pain', easily confused with experiential ones like 'an iron nail can't scratch glass'.
Metaphysics (n.) depends on unimportant-looking details: 'only this is really seen' comes while staring at unchanging surroundings, never while walking about.
Metaphysics (n.) springs from philosophers having the method of science always before their eyes, irresistibly tempted to ask and answer as science does — which leads into complete darkness.
Expectation (n.) someone looks grammatically like shooting him — and since we can't shoot him if he isn't there, we wonder how we can expect what is not the case.
Expectation (n.) need not contain what it expects: waiting for a louder crash may be just an open mouth, a gripping hand, 'this is going to be terrible', and tensions that relax.
Expectation (n.) someone for tea is not one state but a family: checking the diary, laying the table for two, putting out cigarettes, growing impatient, with no single feature common to all.
Expectation (n.) as a tension relieved by someone's arrival would mean we never know whom we expect until he comes, yet surely we do know.
Time (n.) seems a queer thing with something hidden inside, yet all the facts lie open before us; what mystifies us is the noun.
Time (n.) puzzled Augustine — the past is gone, the future not yet, the present has no extension, so how measure it? — because he pictured measuring a travelling band of which we see only a tiny bit.
Time (n.) made into a deity would be, once you look into the grammar of the word, no less astounding an invention than a deity of negation or disjunction.
The First-person pronoun (n.) used as subject recognizes no person, so asking whether it is really you who has the toothache is nonsense.
The First-person pronoun (n.) differs from 'L. W.' even if I am L. W., not by meaning something else but by being a different instrument.
The First-person pronoun (n.) puzzles: 'it is always I who see' does not mean 'always L. W.' — always who, then?
