22102 | Arguing with opponents uncovers truths, and restrains falsehoods [Aquinas] |
Full Idea: There is no better way of uncovering the truth and keeping falsity in check than by arguing with people who disagree with you. | |
From: Thomas Aquinas (On the spiritual perfection of life [1268], 26), quoted by Kretzmann/Stump - Aquinas, Thomas 05 | |
A reaction: Not the sort of attitude you associate with medieval scholastics, who are presumed to be dogmatists. How many modern philosophers actually have the courage to follow this advice? |
15352 | A definition should allow the defined term to be eliminated [Horsten] |
Full Idea: A definition allows a defined term to be eliminated in every context in which it appears. | |
From: Leon Horsten (The Tarskian Turn [2011], 04.2) | |
A reaction: To do that, a definition had better be incredibly comprehensive, so that no nice nuance of the original term is thrown out. |
