People hasten to judge in order not to be judged themselves.

Your success and happiness are forgiven you only if you generously consent to share them. But to be happy it is essential not to be too concerned with others. Consequently, there is no escape. Happy and judged, or absolved and wretched.

Do not wait for the last judgment. It comes every day.

How does it happen that a properly endowed natural scientist comes to concern himself with epistemology? Is there no more valuable work in his specialty? I hear many of my colleagues saying, and I sense it from many more, that they feel this way. I cannot share this sentiment. When I think about the ablest students whom I have encountered in my teaching, that is, those who distinguish themselves by their independence of judgment and not merely their quick-wittedness, I can affirm that they had a vigorous interest in epistemology. They happily began discussions about the goals and methods of science, and they showed unequivocally, through their tenacity in defending their views, that the subject seemed important to them. Indeed, one should not be surprised at this.

The evil that is in the world almost always comes of ignorance, and good intentions may do as much harm as malevolence if they lack understanding.

Man is the only creature that refuses to be what he is.
