18344 | Truth and falsehood must track what does or doesn't exist [Bigelow] |
Full Idea: If something is true, then it would not be possible for it to be false unless either certain things were to exist which don't, or else certain things had not existed which do. | |
From: John Bigelow (The Reality of Numbers [1988], 19) | |
A reaction: This is described by Rami as Bigelow's 'famous' formulation of the idea that 'truth supervenes on being' in a general way. An immediate question would be about fictions. Is Malvolio a stupid man, given that he doesn't exist? We must stretch 'exist'. |
22142 | In future, only logical limits can be placed on divine omnipotence [Anon (Par), by Boulter] |
Full Idea: The Condemnation stipulated that all portions of the ancient intellectual heritage that placed non-logical limits on divine omnipotence were no longer to be tolerated. ...Philosophers now had to entertain the wildest ideas with all seriousness. | |
From: report of Anon (Par) (The Condemnation of 1277 [1277]) by Stephen Boulter - Why Medieval Philosophy Matters 3 | |
A reaction: Boulter identifies this as 'the ultimate source of Hume's philosophical delirium'. Presumably the angels-on-a-pinhead stuff originated with this. It is crazy to think that the only limit on possible existence is logic. Can God make a planet of uranium? |
16716 | It is heresy to require self-evident foundational principles in order to be certain [Anon (Par)] |
Full Idea: Heresy 151: 'To have certainty regarding any conclusion, it must be founded on self-evident principles'. | |
From: Anon (Par) (The Condemnation of 1277 [1277], 151), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 20.3 | |
A reaction: The correct view is obviously to found certainty on faith and authority. It is one thing to be told that foundationalism is a poor theory, but another to be told it is a heresy, and thus a potential capital crime! |
3061 | Anaxarchus said that he was not even sure that he knew nothing [Anaxarchus, by Diog. Laertius] |
Full Idea: Anaxarchus said that he was not even sure that he knew nothing. | |
From: report of Anaxarchus (fragments/reports [c.340 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 09.10.1 |
1866 | It is heresy to teach that history repeats every 36,000 years [Anon (Par)] |
Full Idea: It is heresy to teach that with all the heavenly bodies coming back to the same point after a period of thirty-six thousand years, the same effects as now exist will reappear. | |
From: Anon (Par) (The Condemnation of 1277 [1277], §92) |
14409 | I am a presentist, and all language and common sense supports my view [Bigelow] |
Full Idea: I am a presentist: nothing exists which is not present. Everyone believed this until the nineteenth century; it is writing into the grammar of natural languages; it is still assumed in everyday life, even by philosophers who deny it. | |
From: John Bigelow (Presentism and Properties [1996], p.36), quoted by Trenton Merricks - Truth and Ontology | |
A reaction: The most likely deniers of presentism seem to be physicists and cosmologists who have overdosed on Einstein. On the whole I vote for presentism, but what justifies truths about the past and future. Traces existing in the present? |
1865 | It is heresy to teach that natural impossibilities cannot even be achieved by God [Anon (Par)] |
Full Idea: It is heresy to teach that what is absolutely impossible according to nature cannot be brought about by God or another agent. | |
From: Anon (Par) (The Condemnation of 1277 [1277], §17) |
1864 | It is heresy to teach that we can know God by his essence in this mortal life [Anon (Par)] |
Full Idea: It is heresy to teach that we can know God by his essence in this mortal life. | |
From: Anon (Par) (The Condemnation of 1277 [1277], §9) |
