8011 | Aristotle is a buffoon who has misled the Church [Luther, by MacIntyre] |
Full Idea: Aristotle is a buffoon who has misled the Church. | |
From: report of Martin Luther (talk [1525]) by Alasdair MacIntyre - A Short History of Ethics Ch.10 | |
A reaction: Before he became famous, Luther was a university lecturer on Aristotle. This remark was a hundred years before philosophers began serious criticism of Aristotle. Presumably Protestants just stopped reading him. |
10245 | One geometry cannot be more true than another [Poincaré] |
Full Idea: One geometry cannot be more true than another; it can only be more convenient. | |
From: Henri Poincaré (Science and Method [1908], p.65), quoted by Stewart Shapiro - Philosophy of Mathematics | |
A reaction: This is the culminating view after new geometries were developed by tinkering with Euclid's parallels postulate. |
13160 | To exist and be understood, a multitude must first be reduced to a unity [Leibniz] |
Full Idea: A plurality of things can neither be understood nor can exist unless one first understands the thing that is one, that to which the multitude necessarily reduces. | |
From: Gottfried Leibniz (Notes on Comments by Fardella [1690], Prop 3) | |
A reaction: Notice that it is our need to understand which imposes the unity on the multitude. It is not just some random fiction, or a meaningless mechanical act of thought. |
13161 | Substances are everywhere in matter, like points in a line [Leibniz] |
Full Idea: There are substances everywhere in matter, just as points are everywhere in a line. | |
From: Gottfried Leibniz (Notes on Comments by Fardella [1690], Clarif) | |
A reaction: Since Leibniz is unlikely to believe in the reality of the points, we must wonder whether he was really committed to this infinity of substances. The more traditional notion of substance is always called 'substantial form' by Leibniz. |
6609 | With respect to religion, reason is a blind whore [Luther] |
Full Idea: With respect to the mysteries of the Christian religion, reason is a blind whore. | |
From: Martin Luther (talk [1525]), quoted by Robert Fogelin - Walking the Tightrope of Reason n4.2 | |
A reaction: Reason is presumably a blind whore with respect to all impenetrable mysteries. Since the reason of Aquinas endorsed the mysteries of Christianity, the remark seems a bit strong, but it is appropriate if you think that only faith (in Christianity) matters. |
