Every man if he so desires becomes sculptor of his own brain.

The brain is a world consisting of a number of unexplored continents and great stretches of unknown territory.

As long as our brain is a mystery, the universe, the reflection of the structure of the brain will also be a mystery.

Physical pain is easily forgotten, but a moral chagrin lasts indefinitely.

Heroes and scholars represent the opposite extremes... The scholar struggles for the benefit of all humanity, sometimes to reduce physical effort, sometimes to reduce pain, and sometimes to postpone death, or at least render it more bearable. In contrast, the patriot sacrifices a rather substantial part of humanity for the sake of his own prestige. His statue is always erected on a pedestal of ruins and corpses... In contrast, all humanity crowns a scholar, love forms the pedestal of his statues, and his triumphs defy the desecration of time and the judgment of history.
