10594 | Henkin semantics is more plausible for plural logic than for second-order logic [Maddy] |
Full Idea: Henkin-style semantics seem to me more plausible for plural logic than for second-order logic. | |
From: Penelope Maddy (Second Philosophy [2007], III.8 n1) | |
A reaction: Henkin-style semantics are presented by Shapiro as the standard semantics for second-order logic. |
579 | Cratylus said you couldn't even step into the same river once [Cratylus, by Aristotle] |
Full Idea: Cratylus was appalled that Heraclitus said you could not step twice into the same river, because it was already going too far to admit stepping into the same river once. | |
From: report of Cratylus (fragments/reports [c.425 BCE]) by Aristotle - Metaphysics 1010a | |
A reaction: Compare Idea 427. |
578 | Cratylus decided speech was hopeless, and his only expression was the movement of a finger [Cratylus, by Aristotle] |
Full Idea: Cratylus thought speech of any kind was radically inappropriate and that expression should be restricted exclusively to the movement of the finger. | |
From: report of Cratylus (fragments/reports [c.425 BCE]) by Aristotle - Metaphysics 1010a |
7607 | Nagarjuna and others pronounced the world of experience to be an illusion [Nagarjuna, by Armstrong,K] |
Full Idea: Many later Buddhists (after Nagarjuna, c.120 CE) developed a belief that everything we experience is an illusion: in the West we would call them idealists. | |
From: report of Nagarjuna (teachings [c.120]) by Karen Armstrong - A History of God Ch.3 | |
A reaction: This is just one step beyond Plato (who at least hung onto the immediate world as an inferior reality), and is presumably intended to motivate meditators to break out of the misery of existence into a higher realm. Personally I am against it. |
