Which is more dangerous: fanaticism or atheism? Fanaticism is certainly a thousand times more deadly; for atheism inspires no bloody passion whereas fanaticism does; atheism is opposed to crime and fanaticism causes crimes to be committed.
Let us therefore reject all superstition in order to become more human; but in speaking against fanaticism, let us not imitate the fanatics: they are sick men in delirium who want to chastise their doctors. Let us assuage their ills, and never embitter them, and let us pour drop by drop into their souls the divine balm of toleration, which they would reject with horror if it were offered to them all at once.
Answer me, you who believe that animals are only machines. Has nature arranged for this animal to have all the machinery of feelings only in order for it not to have any at all?

The system of Descartes... seemed to give a plausible reason for all those phenomena; and this reason seemed more just, as it is simple and intelligible to all capacities.

Before receiving your instruction, I must tell you what happened to me one day. I had just had a closet built at the end of my garden. I heard a mole arguing with a cockchafer; 'Here's a fine structure,' said the mole, 'it must have been a very powerful mole who did this work.' 'You're joking,' said the cockchafer; 'it's a cockchafer full of genius who is the architect of this building.' From that moment I resolved never to argue.
