Science has made us gods even before we are worthy of being men.
Science had better not free the minds of men too much, before it has tamed their instincts.
Truth is always served by great minds, even if they fight it.
Never feel remorse for what you have thought about your wife; she has thought much worse things about you.
Kill one man, and you are murderer.
What scientist would not long to go on living, if only to see how the little truths he has brought to light will grow up?
