The value of achievement lies in the achieving.

It is impossible to solve significant problems using the same knowledge that created them.

A ship is always safe at the shore - but that is NOT what it is built for.

All that's different about me is that I still ask the questions most people stopped asking at age five.

What you can't imagine, you can't discover.

A life directed chiefly toward the fulfillment of personal desires will sooner or later always lead to bitter disappointment.

I fully agree with you about the significance and educational value of as well as history and philosophy of science. So many people today - and even professional - seem to me like someone who has seen thousands of trees but has never seen a forest. A knowledge of the historic and philosophical background gives that kind of independence from prejudices of his generation from which most scientists are suffering. This independence created by philosophical insight is - in my opinion - the mark of distinction between a mere artisan or specialist and a real seeker after truth.
