4037 | Ockham's Razor is the principle that we need reasons to believe in entities [Mellor/Oliver] |
Full Idea: Ockham's Razor is the principle that we need reasons to believe in entities. | |
From: DH Mellor / A Oliver (Introduction to 'Properties' [1997], §9) | |
A reaction: This presumably follows from an assumption that all beliefs need reasons, but is that the case? The Principle of Sufficient Reason precedes Ockham's Razor. |
14100 | Figuring in the definition of a thing doesn't make it a part of that thing [Rosen] |
Full Idea: From the simple fact that '1' figures in the definition of '2', it does not follow that 1 is part of 2. | |
From: Gideon Rosen (Metaphysical Dependence [2010], 10) | |
A reaction: He observes that quite independent things can be mentioned on the two sides of a definition, with no parthood relation. You begin to wonder what a definition really is. A causal chain? |
