9 ideas
1813 | All reasoning endlessly leads to further reasoning (Mode 12) [Agrippa, by Diog. Laertius] |
Full Idea: Twelfth mode: all reasoning leads on to further reasoning, and this process goes on forever. | |
From: report of Agrippa (fragments/reports [c.60]) by Diogenes Laertius - Lives of Eminent Philosophers 09.Py.10 |
1811 | Proofs often presuppose the thing to be proved (Mode 15) [Agrippa, by Diog. Laertius] |
Full Idea: Fifteenth mode: proofs often presuppose the thing to be proved. | |
From: report of Agrippa (fragments/reports [c.60]) by Diogenes Laertius - Lives of Eminent Philosophers 09.Py.10 |
1815 | Reasoning needs arbitrary faith in preliminary hypotheses (Mode 14) [Agrippa, by Diog. Laertius] |
Full Idea: Fourteenth mode: reasoning requires arbitrary faith in preliminary hypotheses. | |
From: report of Agrippa (fragments/reports [c.60]) by Diogenes Laertius - Lives of Eminent Philosophers 09.Py.10 |
1812 | All discussion is full of uncertainty and contradiction (Mode 11) [Agrippa, by Diog. Laertius] |
Full Idea: Eleventh mode: all topics of discussion are full of uncertainty and contradiction. | |
From: report of Agrippa (fragments/reports [c.60]) by Diogenes Laertius - Lives of Eminent Philosophers 09.Py.10 |
8850 | Agrippa's Trilemma: justification is infinite, or ends arbitrarily, or is circular [Agrippa, by Williams,M] |
Full Idea: Agrippa's Trilemma offers three possible outcomes for a regress of justification: the chain goes on for ever (infinite); or the chain stops at an unjustified proposition (arbitrary); or the chain eventually includes the original proposition (circular). | |
From: report of Agrippa (fragments/reports [c.60], §2) by Michael Williams - Without Immediate Justification §2 | |
A reaction: This summarises Ideas 1911, 1913 and 1914. Agrippa's Trilemma is now a standard starting point for modern discussions of foundations. Personally I reject 2, and am torn between 1 (+ social consensus) and 3 (with a benign, coherent circle). |
1814 | Everything is perceived in relation to another thing (Mode 13) [Agrippa, by Diog. Laertius] |
Full Idea: Thirteenth mode: everything is always perceived in relation to something else. | |
From: report of Agrippa (fragments/reports [c.60]) by Diogenes Laertius - Lives of Eminent Philosophers 09.Py.10 |
4691 | If all mental life were conscious, we would be unable to see things, or to process speech [McGinn] |
Full Idea: If there were nothing more to our mind than our conscious awareness, then we would be unable to see anything or to process speech. | |
From: Colin McGinn (The Making of a Philosopher [2002], Ch. 6) | |
A reaction: A vital point. Traditional dualism has left us a simplistic exaggeration of the role of consciousness, and the misapprehension that most of what we do is conscious - which it clearly isn't, once you think about it. |
4690 | If meaning is speaker's intentions, it can be reduced to propositional attitudes, and philosophy of mind [McGinn] |
Full Idea: The importance of Grice's analysis of speaker meaning is that it offers the prospect of analysing the whole phenomenon of linguistic meaning in terms of propositional attitudes… thus turning semantics into a department of the philosophy of mind. | |
From: Colin McGinn (The Making of a Philosopher [2002], Ch. 5) | |
A reaction: Although meaning being truth conditions is the most cited theory, the reduction of semantics to an aspect of mind also seems almost orthodox now. But how do the symbols 'represent' the attitudes? |
9287 | Bruno said that ancient Egyptian magic was the true religion [Bruno, by Yates] |
Full Idea: Giordano Bruno maintained that the magical Egyptian religion of the world was not only the most ancient but also the only true religion, which both Judaism and Christianity had obscured and corrupted. | |
From: report of Giordano Bruno (works [1590]) by Frances A. Yates - Giordano Bruno and Hermetic Tradition Ch.1 | |
A reaction: His beliefs were based on the Hermetic writings. No wonder he was burned at the stake. Atheists now lay flowers at his memorial in Rome. The sixteenth century was when the hunt for alternatives to established religion began. |
