“Truly to be free, my choices must truly be mine—must accord with the “me” with which I associate my core identity. I must make them in keeping with rational life plans. They cannot be triggered by invisible external or covert influences; they must make manifest a will that is unfettered yet rationally informed by life plans.”

“I must remember the things I have seen. I must keep them fresh in memory, see them again in my mind's eye, live through them again and again in my thoughts. And most of all, I must make good use of them in tomorrow's life.”

“Do you truly believe that life is fair, Senor de la Vega?
-No, maestro, but I plan to do everything in my power to make it so.”

“For a city or a people to be truly free they must have the secure right, without economic, political or police pressure, to make their own choice and to live their own lives.”

“You are given the free will, or choices in life; but you must be widely awake to make wise decisions.”

“A rational disposition must necessarily preclude a romantic outlook in life”

“Just as every tree starts as a seed and the baby an embryo. Your plans must follow the same steps if you truly wish to see them successful at the end.”

“I have lived my life according to this principle: If I'm afraid of it, then I must do it.”

“Everything in my life is planned. It adds stability, but it makes me yearn for something that's not planned, that's spontaneous.”

“Knowledge begins with practice, and theoretical knowledge, which is acquired through practice, must then return to practice. The active function of knowledge manifests itself not only in the active leap from perceptual to rational knowledge, but - and this is more important - it must manifest itself in the leap from rational knowledge to revolutionary practice.”
