A little Learning is a dang'rous Thing;
Drink deep, or taste not the Pierian Spring:
There shallow Draughts intoxicate the Brain,
And drinking largely sobers us again.
-Alexander Pope
I never submitted the whole system of my opinions to the creed of any party of men whatever in religion, in philosophy, in politics, or in anything else where I was capable of thinking for myself. Such an addiction is the last degradation of a free and moral agent.
-Thomas Jefferson
We will be braver men, stronger and less idle, if we believe that one must search for the things one does not know, rather than if we believe that it is not possible to find out what we do not know and that one must not look for it.
-Socrates
