8828 | Truth is rational acceptability [Putnam] |
Full Idea: Truth, in the only sense in which we have a vital and working notion of it, is rational acceptability. | |
From: Hilary Putnam (Why Reason Can't be Naturalized [1981]) | |
A reaction: I smell a circularity somewhere in there, probably in 'rational', though it could be in 'acceptable'. Putnams's views on truth tend to shift a lot. He denies that evolutionary survival is a criterion. |
13304 | Learned men gain more in one day than others do in a lifetime [Posidonius] |
Full Idea: In a single day there lies open to men of learning more than there ever does to the unenlightened in the longest of lifetimes. | |
From: Posidonius (fragments/reports [c.95 BCE]), quoted by Seneca the Younger - Letters from a Stoic 078 | |
A reaction: These remarks endorsing the infinite superiority of the educated to the uneducated seem to have been popular in late antiquity. It tends to be the religions which discourage great learning, especially in their emphasis on a single book. |
20820 | Time is an interval of motion, or the measure of speed [Posidonius, by Stobaeus] |
Full Idea: Posidonius defined time thus: it is an interval of motion, or the measure of speed and slowness. | |
From: report of Posidonius (fragments/reports [c.95 BCE]) by John Stobaeus - Anthology 1.08.42 | |
A reaction: Hm. Can we define motion or speed without alluding to time? Looks like we have to define them as a conjoined pair, which means we cannot fully understand either of them. |
7598 | Zoroaster and the Hebrew prophets evolved different versions of monotheism [Zoroaster, by Armstrong,K] |
Full Idea: Zoroaster and the Hebrew prophets evolved different versions of monotheism. | |
From: report of Zoroaster (The Gathas (seventeen hymns) [c.900 BCE]) by Karen Armstrong - A History of God Ch.1 | |
A reaction: This seems to be the consensus on the origins of monotheism, which places the development much earlier than the appearance of the idea in Greek philosophy. |
7472 | Zarathustra was the first to present a god who is an abstract concept [Zoroaster] |
Full Idea: Zarathustra's achievement was for the first time to present a god who is an abstract concept - he broke with the tradition of a pantheon of gods. | |
From: Zoroaster (The Gathas (seventeen hymns) [c.900 BCE]), quoted by Peter Watson - Ideas Ch.05 | |
A reaction: The more abstract the gods become, the harder it is to challenge their existence. |
20672 | Zoroastrianism saw the world as a battle between good evil gods [Zoroaster, by Harari] |
Full Idea: Zoroastrianism saw the world as a cosmic battle between the good god Ahura Mazda and the evil god Angra Mainyu. | |
From: report of Zoroaster (The Gathas (seventeen hymns) [c.900 BCE]) by Yuval Noah Harari - Sapiens: brief history of humankind 12 'Battle' | |
A reaction: Hm. This contradicts the impression I had gained that it was monotheist. |
