What and How We Know
 
The Quotable Bertrand Russell (ed. Lee Eisler, Buffalo, NY: Prometheus, 1993), p. 294.
When one admits that nothing is certain, one must, I think, also add that some things are much more nearly certain than others.
The Quotable Bertrand Russell (ed. Lee Eisler, Buffalo, NY: Prometheus, 1993), p. 219.
Roughly, science is what we know and philosophy is what we don't know.
The Quotable Bertrand Russell, Lee Eisler, ed. (Prometheus, 1993), p. 106.
It is the things for which there is no evidence that are believed with passion. "Nobody feels any passion about the multiplication table or about the existence of Cape Horn, because these matters are not doubtful. "But in matters of theology or political theory, where a rational man will hold that at best there is a slight balance of probability on one side or the other, people argue with passion and support their opinions by physical slavery imposed by armies and mental slavery imposed by schools.
The Rediscovery of the Mind (MIT Press: 1992), p. 11.
[Speaking descriptively. This is not Searle's view.] Every fact in the universe is in principle knowable and understandably by human investigators. Because reality is physical, and because science concerns the investigation of physical reality, and because there are no limits on what we can know of physical reality, it follows that all of the facts in the universe are knowable and understandable by us.
Atheism: A Philosophical Justification (Philadelphia: Temple University Press, 1990), p. 463.
Since experiences of God are good grounds for the existence of God, are not experiences of the absence of God good grounds for the nonexistence of God? After all, many people have tried to experience God and have failed. Cannot these experiences of the absence of God be used by atheists to counter the theistic argument based on experience of the presence of God?
Atheism: A Philosophical Justification (Philadelphia: Temple University Press, 1990), p. 463.
Religious experiences are like those induced by drugs, alcohol, mental illness, and sleep deprivation: They tell no uniform or coherent story, and there is no plausible theory to account for discrepancies among them.
Realism and Reason (Cambridge University Press: 1985), p. 246.
Why should we expend our mental energy in convincing ourselves that we aren't thinkers, that our thoughts aren't really about anything, noumenal or phenomenal, that there is no sense in which any thought is right or wrong (including the thought that no thought is right or wrong) beyond being the verdict of the moment, and so on? This is a self-refuting enterprise if there ever was one! Let us recognize that one of our fundamental self-conceptualizations ... is that we are thinkers, and that as thinkers we are committed to there being some kind of truth, some kind of correctness which is substantial.... That means that there is no eliminating the normative.
"The Use and Abuse of Political Terms" in Tait's Edinburgh Magazine, Vol. 1, ed. William Tait, Unattributed (W. Tait: 1832), p. 167.
We desiderate in it somewhat more of what becomes all men, but, most of all, a young man, to whom the struggles of life are only in their commencement, and whose spirt cannot yet have been wounded, or his temper embittered by hostile collision with the world, but which, in young men especially, is apt to be wanting — a slowness to condemn. A man must now learn, by experience, what once came almost by nature to those who had any faculty of seeing; to look upon all things with a benevolent, but upon great men and their works with a reverential spirit; rather to seek in them for what he may learn from them, than for opportunities of showing what they might have learned from him; to give such men the benefit of every possibility of their having spoken with a rational meaning; not easily or hastily to persuade himself that men like Plato, and Locke, and Rousseau, and Bentham, gave themselves a world of trouble in running after something which they thought was a reality, but which he Mr. A. B. can clearly see to be an unsubstantial phantom; to exhaust every other hypothesis, before supposing himself wiser than they; and even then to examine, with good will and without prejudice, if their error do not contain some germ of truth...
God the Problem, (Cambridge: Harvard University Press, 1972), p. 7.
The central problem of theological discourse, not shared with any other "language game," is the meaning of the term "God." "God" raises special problems of meaning because it is a noun which by definition refers to a reality transcendent of, and thus not locatable within, experience. A new convert may wish to refer the "warm feeling" in his heart to God, but God is hardly to be identified with this emotion; the biblicist may regard the Bible as God's Word; the moralist may believe God speaks through men's consciences; the churchman may believe God is present among his people — but each of these would agree that God himself transcends the locus referred to. As the Creator or Source of all that is, God is not to be identified with any particular finite reality; as the proper object of ultimate loyalty or faith, God is to be distinguished from every proximate or penultimate value or being. But if absolutely nothing within our experience can be directly identified as that to which the term "God" properly refers, what meaning does or can the word have?
Tragic Sense of Life, trans. J.E. Crawford Flitch (Dover: 1954), orig. 1921, p. 15.
All knowledge has an ultimate object. Knowledge for the sake of knowledge is, say what you will, nothing but a dismal begging of the question. We learn something either for an immediate practical end, or in order to complete the rest of our knowledge. Even the knowledge that appears to us to be most theoretical — that is to say, of least immediate application to the non-intellectual necessities of life — answers to a necessity which is no less real because it is intellectual, to a reason of economy in thinking, to a principle of unity and continuity of consciousness. But just as a scientific fact has its finality in the rest of knowledge, so the philosophy that we would make our own has also its extrinsic object — it refers to our whole destiny, to our attitude in face of life and the universe. And the most tragic problem of philosophy is to reconcile intellectual necessities with the necessities of the heart and the will. For it is on this rock that every philosophy that pretends to resolve the eternal and tragic contradiction, the basis of our existence, breaks to pieces.
