“They never open their mouths without subtracting from the sum of human knowledge.”

“No matter how limited their powers of reason might have been. still they must have understood that living like that was just murder, a capital crime - except it was slow, day-by-day murder. The government (or humanity) could not permit capital punishment for one man, but they permitted the murder of millions a little at a time. To kill one man - that is, to subtract 50 years from the sum of all human lives - that was a crime; but to subtract from the sum of all human lives 50,000,000 years - that was not a crime! No, really, isn't it funny? This problem in moral math could be solved in half a minute by any ten-year-old Number today, but they couldn't solve it. All their Kant's together couldn't solve it (because it never occurred to one of their Kant's to construct a system of scientific ethics - that is, one based on subtraction, addition, division, and multiplication).”

“Without power, knowledge is useless. without knowledge, faith is tyranny. Without understanding, humanity is blind, and without all four, it is doomed.”

“Human existence is based upon two pillars: Compassion and knowledge. Compassion without knowledge is ineffective; knowledge without compassion is inhuman.”

“But without doubts, without a standpoint reached through questionings, human beings can't acquire knowledge.”

“Knowledge was never simply born in the human mind; it was always reborn. The relaying of wisdom from one age to the next, this cycle of rebirths: this was wisdom.”
