The entire history of science is a progression of exploded fallacies.

Do you know the hallmark of the second-rater? It's resentment of another man's achievement.

A spirit, too, needs fuel. It can run dry.

Live and act within the limit of your knowledge and keep expanding it to the limit of your life. Redeem your mind from the hockshops of authority. Accept the fact that you are not omniscient, but playing a zombie will not give you omniscience-that your mind is fallible, but becoming mindless will not make you infallible-that an error made on your own is safer than ten truths accepted on faith, because the first leaves you the means to correct it, but the second destroys your capacity to distinguish truth from error.

The uncontested absurdities of today are the accepted slogans of tomorrow.

There’s no way to rule innocent men. The only power any government has is the power to crack down on criminals. Well, when there aren’t enough criminals, one makes them. One declares so many things to be a crime that it becomes impossible for me to live without breaking laws. Who wants a nation of law-abiding citizens? What’s there in that for anyone? But just pass the kind of laws that can neither be observed or enforced nor objectively interpreted - and you create a nation of law-breakers - and then you cash in on guilt.

Within the extent of your knowledge, you are right.
