Philosophy
Zeno held that happiness is not merely dependent upon present enjoyment and prosperity, but also on a reasonable expectation of their continuance and appreciation.
Zeno's writings have not survived, but among the charred papyrus remains at the Villa of the Papyri at Herculaneum, there is an Epitome of Conduct and Character from the Lectures of Zeno written by his pupil Philodemus. It contains the essays On Frank Criticism and On Anger.
Zeno also studied the philosophy of mathematics based on the derivation of all knowledge from experience. He criticized Euclid, seeking to show that deductions from the fundamental principles (Greek: ἀρχαί) of geometry cannot, on their own, be proved:
admit the principles but deny that the propositions coming after the principles can be demonstrated unless they grant something that is not contained in the principles. This method of controversy was followed by Zeno of Sidon, who belonged to the school of Epicurus, and against whom Posidonius has written a whole book.Read more about this topic: Zeno Of Sidon
Famous quotes containing the word philosophy:
“Methinks it would be some advantage to philosophy if men were named merely in the gross, as they are known. It would be necessary only to know the genus and perhaps the race or variety, to know the individual. We are not prepared to believe that every private soldier in a Roman army had a name of his own,—because we have not supposed that he had a character of his own.”
—Henry David Thoreau (1817–1862)
“The new statement will comprise the skepticisms, as well as the faiths of society, and out of unbeliefs a creed shall be formed. For, skepticisms are not gratuitous or lawless, but are limitations of the affirmative statement, and the new philosophy must take them in, and make affirmations outside of them, just as much as must include the oldest beliefs.”
—Ralph Waldo Emerson (1803–1882)
“Histories make men wise; poets witty; the mathematics subtle; natural philosophy deep; moral grave; logic and rhetoric able to contend.”
—Francis Bacon (1561–1626)
