The difficulty in philosophy is to say no more than we know.
Ludwig Wittgenstein
» Ludwig Wittgenstein - all quotes »
Our design, not respecting arts, but philosophy, and our subject, not manual, but natural powers, we consider chiefly those things which relate to gravity, levity, elastic force, the resistance of fluids, and the like forces, whether attractive or impulsive; and therefore we offer this work as mathematical principles of philosophy; for all the difficulty of philosophy seems to consist in this — from the phenomena of motions to investigate the forces of nature, and then from these forces to demonstrate the other phenomena...
Isaac Newton
A difficulty which confronts the synechistic philosophy is this. In considering personality, that philosophy is forced to accept the doctrine of a personal God; but in considering communication, it cannot but admit that if there is a personal God, we must have a direct perception of that person and indeed be in personal communication with him. Now, if that be the case, the question arises how it is possible that the existence of this being should ever have been doubted by anybody. The only answer that I can at present make is that facts that stand before our face and eyes and stare us in the face are far from being, in all cases, the ones most easily discerned. That has been remarked since time immemorial.
Charles Sanders Peirce
Philosophy—reduced, as we have seen, to philosophical discourse—develops from this point on in a different atmosphere and environment from that of ancient philosophy. In modern university philosophy, philosophy is obviously no longer a way of life, or a form of life—unless it be the form of life of a professor of philosophy.
Pierre Hadot
My path was not the normal one of professors of philosophy. I did not intend to become a doctor of philosophy by studying philosophy (I am in fact a doctor of medicine) nor did I by any means, intend originally to qualify for a professorship by a dissertation on philosophy. To decide to become a philosopher seemed as foolish to me as to decide to become a poet. Since my schooldays, however, I was guided by philosophical questions. Philosophy seemed to me the supreme, even the sole, concern of man. Yet a certain awe kept me from making it my profession.
Karl Jaspers
Believe me, nurse, the difficulty of beginning will be nothing to the difficulty of knowing how to stop. At least that's the way it is with me when I have to make a speech. Someone's got to catch hold of my coat-tails and pull me down by main force.
