Heroes to me are guys that sit in libraries. They absorb knowledge and then the risks they take are calculated on the basis of the courage it took to become replete with knowledge.

I gained direct knowledge of the life of the poor in big towns: I have lived the narrowing mechanism of its conditioning and feared it.

The courage of a soldier is heightened by his knowledge of his profession.

If information and knowledge are central to democracy, they are conditions for development.

Knowledge is a weapon. I intend to be formidably armed.
