There are no evil thoughts, except one: the refusal to think.
Never think of pain or danger or enemies a moment longer than is necessary to fight them.
The goal of mathematics is "the task of bringing the universe within the range of man’s knowledge by identifying relationships to data we perceive"
I do not want the peace which bypasses understanding, I want the understanding which brings peace.
If a man will begin with certainties, he shall end in doubts; but if he will be content to begin with doubts, he shall end in certainties.
