Since programmers create programs out of nothing, imagination is our only limitation. Thus, in the world of programming, the hero is the one who has great vision. Paul Graham is one of our contemporary heroes. He has the ability to embrace the vision, and to express it plainly. His works are my favorites, especially the ones describing language design. He explains secrets of programming, languages, and human nature that can only be learned from the hacker experience. This book shows you his great vision, and tells you the truth about the nature of hacking. -- Yukihiro "Matz" Matsumoto, creator of Ruby

The function of wisdom is to discriminate between good and evil. -- Cicero

A society that puts equality -- in the sense of equality of outcome -- ahead of freedom will end up with neither equality nor freedom.

An interpreter raises the machine to the level of the user program; a compiler lowers the user program to the level of the machine language. -- SICP

Whenever you find yourself on the side of the majority, it is time to pause and reflect. -- Mark Twain

We can easily forgive a child who is afraid of the dark; the real tragedy of life is when men are afraid of the light. –Plato
