Quotes about reason

"One must command from each what each can perform," the king went on. "Authority is based first of all upon reason. If you command your subjects to jump into the ocean, there will be a revolution. I am entitled to command obedience because my orders are reasonable."

"Then my sunset?" insisted the little prince, who never let go of a question once he had asked it.

All our reasoning boils down to yielding to sentiment.

You doom yourselves, Susannah. You seem positively bent on it, and the root is always the same: your faith fails you, and you replace it with rational thought. But there is no love in thought, nothing that lasts in deduction, only death in rationalism.

The sad fact of the human species that High Consul Duarte understood so well was that you could never overcome tribalism and jingoism with an argument. Tribalism was an irrational position, and it was impossible to defeat an irrational position with a rational argument.

The irony is that in shifting the focus onto the individual human mind, which everyone agrees can be a pretty flimsy and wayward organ, Descartes had arrived at the closest thing to a certain basis for knowledge. If my own thoughts are the only indubitable ground I can stand on, apparently they aren’t so flimsy after all, at least not all the time. As an earlier follower of Descartes put it, “doubt is the beginning of an undoubtable philosophy.” Therefore the mind and its “good sense”—that is to say, human reason—are the only basis for judging whether a thing is true. With the “cogito,” as philosophers abbreviate it, and with the theory of knowledge that arises from it, which Descartes outlined in the Discourse on the Method and later works, human reason supplanted received wisdom. Once Descartes had established the base, he and others could rebuild the edifice of knowledge. But it would be different from what it had been. Everything would be different.
