Science does not promise absolute truth, nor does it consider that such a thing necessarily exists. Science does not even promise that everything in the Universe is amenable to the scientific process.

When I die I won't go to heaven or hell; there will just be nothingness.

The day you stop learning is the day you begin decaying.

Theories are not so much wrong as incomplete

Scientific apparatus offers a window to knowledge, but as they grow more elaborate, scientists spend ever more time washing the windows.

Suppose that we are wise enough to learn and know - and yet not wise enough to control our learning and knowledge, so that we use it to destroy ourselves? Even if that is so, knowledge remains better than ignorance. It is better to know - even if the knowledge endures only for the moment that comes before destruction - than to gain eternal life at the price of a dull and swinish lack of comprehension of a universe that swirls unseen before us in all its wonder. That was the choice of Achilles, and it is mine, too.

You show me someone who can't understand people and I'll show you someone who has built up a false image of himself.
