“In order to determine whether or not one sentence is a consequence of another, no reference need be made to the meaning of the sentences. The mere statement of the truth-values is certainly too little; but the statement of the meaning is, on the other hand, too much. It is sufficient that the syntactical design of the sentences be given.”

— Rudolf Carnap

“Logic is not concerned with human behavior in the same sense that physiology, psychology, and social sciences are concerned with it. These sciences formulate laws or universal statements which have as their subject matter human activities as processes in time. Logic, on the contrary, is concerned with relations between factual sentences (or thoughts). If logic ever discusses the truth of factual sentences it does so only conditionally, somewhat as follows: if such-and-such a sentence is true, then such-and-such another sentence is true. Logic itself does not decide whether the first sentence is true, but surrenders that question to one or the other of the empirical sciences.”

“By the logical syntax of a language, we mean the formal theory of the linguistic forms of that language -- the systematic statement of the formal rules which govern it together with the development of the consequences which follow from these rules. A theory, a rule, a definition, or the like is to be called formal when no reference is made in it either to the meaning of the symbols (for examples, the words) or to the sense of the expressions (e. g. the sentences), but simply and solely to the kinds and order of the symbols from which the expressions are constructed.”

“The various structures of sentences in any given language, comprising for example at least two nominal pieces and a verbal piece must be collated, and such categories as voice, mood, affirmative, negative, tense, aspect, gender, number, person and case, if found applicable and valid in descriptive statement, are to be abstracted from, and referred back to the sentence as a whole.”

“We completely ignore the human value of the information. A selection of 100 letters is given a certain information value, and we do not investigate whether it makes sense in English, and, if so, whether the meaning of the sentence is of any practical importance. According to our definition, a set of 100 letters selected at random (according to the rules of Table 1.1), a sentence of 100 letters from a newspaper, a piece of Shakespeare or a theorem of Einstein are given exactly the same informational value.”

“At fourteen months he began speaking in sentences, short and of his own structure, but sentences. The subjects of his conversation, or, rather, his statements, were consistently egocentric. Normal again—no one expects an infant to write essays on the beauties of altruism.”

“If, in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence passed on to the next generation of creatures, what statement would contain the most information in the fewest words? I believe it is the atomic hypothesis (or the atomic fact, or whatever you wish to call it) that all things are made of atoms — little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one another. In that one sentence, you will see, there is an enormous amount of information about the world, if just a little imagination and thinking are applied.”

“Know what makes a sentence more than a random list, practice constructing sentences and explaining what you have done, and you will know how to make sentences forever and you will know too when what you are writing doesn't make the grade because it has degenerated into a mere pile of discrete items.”

“One day, maybe not in the next few weeks, but certainly in the conceivable future, someone will be able to refer to me without using the word 'arse' somewhere in the sentence.”
