Men are mortal, but ideas are immortal.
True opinions can prevail only if the facts to which they refer are known; if they are not known, false ideas are just as effective as true ones, if not a little more effective.
It is not the idea as such which the censor attacks, whether it be heresy or radicalism or obscenity. He attacks the circulation of the idea among the classes which in his judgment are not to be trusted with the idea.
Creative ideas come to the intuitive person who can face up to the insecurity of looking beyond the obvious.
Men command fewer words than they have ideas to express, and language, as Jean Paul said, is a dictionary of faded metaphors.
There is nothing disastrous in the temporary nature of our ideas. They are always that. But there may very easily be a train of evil in the self-deception which regards them as final. I think God will forgive us our skepticism sooner than our Inquisitions.
It is so much easier to talk of poverty than to think of the poor, to argue the rights of capital than to see its results. Pretty soon we come to think of the theories and abstract ideas as things in themselves.
The thinker dies, but his thoughts are beyond the reach of destruction. Men are mortal; but ideas are immortal.
Whenever we accept an idea as authority instead of as instrument, an idol is set up. We worship the plough, and not the fruit.
Unless our ideas are questioned, they become part of the furniture of eternity.
