The chief benefit, which results from philosophy, arises in an indirect manner, and proceeds more from its secret, insensible influence, than from its immediate application.

Generally speaking, the errors in religion are dangerous; those in philosophy only ridiculous.

Be a philosopher but, amid all your philosophy be still a man.

Philosophy would render us entirely Pyrrhonian, were not nature too strong for it.

In both religion and science, some people are dishonest, exploitative, incompetent and exhibit other human failings.

What we see today is an American economy that has boomed because of policies and developments of the 1950s and '60s: the interstate-highway system, massive funding for science and technology, a public-education system that was the envy of the world and generous immigration policies.

From the time I was a student, I think I was very confident in my raw abilities. I would think that, given a problem, I was as likely to solve it as anybody. But that's not enough in science to succeed, really.

I feel genius in great works of art. I have seen medical cures that science can't explain, some seemingly triggered by faith. The same is true of millions of other people.
