“We are at the very beginning of time for the human race. It is not unreasonable that we grapple with problems. But there are tens of thousands of years in the future. Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on.”
― Richard P. Feynman

“They who can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety.”
― Benjamin Franklin, Memoirs of the life & writings of Benjamin Franklin

“Argue for your limitations and, sure enough, they're yours.”
― Richard Bach, Illusions: The Adventures of a Reluctant Messiah

“I think it's much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers and possible beliefs and different degrees of uncertainty about different things, but I am not absolutely sure of anything and there are many things I don't know anything about, such as whether it means anything to ask why we're here. I don't have to know an answer. I don't feel frightened not knowing things, by being lost in a mysterious universe without any purpose, which is the way it really is as far as I can tell.”
― Richard P. Feynman
