Experience has taught me a technique for dealing with such people [...] I counter the devotees of the Great Pyramid by adoration of the Sphinx; and the devotee of nuts by pointing out that hazelnuts and walnuts are as deleterious as other foods and only Brazil nuts should be tolerated. But when I wa

The twin conceptions of sin and vindictive punishment seem to be at the root of much that is most vigorous, both in religion and politics.
Aristotle is the last Greek philosopher who faces the world cheerfully; after him, all have, in one form or another, a philosophy of retreat.
The philosophies that have been inspired by scientific technique are power philosophies, and tend to regard everything non-human as mere raw material. Ends are no longer considered; only the skillfulness of the process is valued. This also is a form of madness. It is, in our day, the most dangerous
What the world needs is not dogma but an attitude of scientific inquiry.
To the young I should offer two maxims: Don't accept superficial solutions of difficult problems. It is better to do a little good than much harm. I should not offer anything more specific; every young person should decide on his or her own credo.

I greatly doubt whether the men who become pirate chiefs are those who are filled with retrospective terror of their fathers, or whether Napoleon , at Austerlitz, really felt that he was getting even with Madame MÃ¨re. I know nothing of the mother of Attila , but I rather suspect that she spoilt the

We are condemned to kill time, thus we die bit by bit. - Octavio Paz The time you enjoy wasting is not wasted time.
