P. F. Strawson

"The distinction between identifying reference and uniquely existential assertion is something quite undeniable. The sense in which the existence of something answering to a definite description used for the purpose of identifying reference, and its distinguishability by an audience from anything else, is presupposed and not asserted in an utterance containing such an expression, so used, stands absolutely firm, whether or not one opts for the view that radical failure of the presupposition would deprive the statement of a truth-value. It remains a decisive objection to the theory of Descriptions... that... it amounts to a denial of these undeniable distinctions."

"[A] man who contradicts himself may have succeeded in exercising his vocal chords. But from the point of view of imparting information, of communicating facts (or falsehoods) it is as if he had never opened his mouth. He utters words, but does not say anything."

"There is a massive central core of human thinking which has no history — or none recorded in histories of thought; there are categories and concepts which, in their most fundamental character, change not at all. Obviously these are not the specialities of the most refined thinking. They are the commonplaces of the least refined thinking; and are yet the indispensable core of the conceptual equipment of the most sophisticated human beings. It is with these, their interconnexions, and the structure that they form, that a descriptive metaphysics will be primarily concerned."

"Part of my aim is to exhibit some general and structural features of the conceptual scheme in terms of which we think about particular things."

"Peter Frederick Strawson (1919–2006) was an Oxford-based philosopher whose career spanned the second half of the twentieth century. He wrote most notably about the philosophy of language, metaphysics, epistemology and the history of philosophy, especially Kant."

"Metaphysics has a long and distinguished history, and it is consequently unlikely that there are any new truths to be discovered in descriptive metaphysics. But this does not mean that the task of descriptive metaphysics has been, or can be, done once for all. It has constantly to be done over again. If there are no new truths to be discovered, there are old truths to be rediscovered. For though the central subject-matter of descriptive metaphysics does not change, the critical and analytical idiom of philosophy changes constantly. Permanent relationships are described in an impermanent idiom, which reflects both the age’s climate of thought and the individual philosopher’s personal style of thinking. No philosopher understands his predecessors until he has re-thought their thought in his own contemporary terms; and it is characteristic of the very greatest philosophers, like Kant and Aristotle, that they, more than any others, repay this effort of re-thinking"

"Neither Aristotelian nor Russellian rules give the exact logic of any expression of ordinary language; for ordinary language has no exact logic."

"It remains to mention some of the ways in which people have spoken misleadingly of logical form. One of the commonest of these is to talk of the logical form of a statement; as if a statement could never have more than one kind of formal power; as if statements could, in respect of their formal powers, be grouped in mutually exclusive classes, like animals at a zoo in respect of their species. But to say that a statement is of some one logical form is simply to point to a certain general class of, e.g., valid inferences, in which the statement can play a certain role. It is not to exclude the possibility of there being other general classes of valid inferences in which the statement can play a certain role."

"Strawson first gained philosophical fame at the age of 29 in 1950, when he criticised Bertrand Russells renowned Theory of Descriptions for failing to do justice to the richness of ordinary language. Strawson, an intellectual prize-fighter, soon took on the Oxford ordinary language philosopher, J. L. Austin, and the American giant of logic, Willard van Orman Quine. Strawson, even more than Hume, Kant and Wittgenstein, insisted on the richness and ineluctability of ordinary language and natural beliefs. In Individuals (1959) and The Bounds of Sense (1966), he sought to give a rational account of beliefs "stubbornly held … at a primitive level of reflection"; these, even if rejected, or apparently rejected, by philosophers "at a more sophisticated level of reflection", are what we are all "naturally and inescapably committed to"."
