Kind words do not cost much. Yet they accomplish much.

It is dangerous to tell the people that the laws are unjust; for they obey them only because they think them just. Therefore it isnecessary to tell them at the same time that they must obey them because they are laws, just as they must obey superiors, not because they are just, but because they are superiors. In this way all sedition is prevented.

Fear not, provided you fear; but if you fear not, then fear.

We are fools to depend upon the society of our fellow-men. Wretched as we are, powerless as we are, they will not aid us; we shall die alone.

The heart has its reasons of which reason knows nothing. We feel it in a thousand things. I say that the heart naturally loves the Universal Being, and naturally loves itself; and it gives itself to one or the other, and hardens itself against one or the other, as it chooses...it is the heart that feels God, not the reason; this is faith.

If they [Plato and Aristotle] wrote about politics it was as if to lay down rules for a madhouse. And if they pretended to treat it as something really important it was because they knew that the madmen they were talking to believed themselves to be kings and emperors. They humored these beliefs in order to calm down their madness with as little harm as possible.

As we speak of poetical beauty, so ought we to speak of mathematical beauty and medical beauty. But we do not do so; and that reason is that we know well what is the object of mathematics, and that it consists in proofs, and what is the object of medicine, and that it consists in healing. But we do not know in what grace consists, which is the object of poetry.
