10272 | The notion of 'object' is at least partially structural and mathematical [Shapiro] |
Full Idea: The very notion of 'object' is at least partially structural and mathematical. | |
From: Stewart Shapiro (Philosophy of Mathematics [1997], 8.1) | |
A reaction: [In the context, Shapiro clearly has physical objects in mind] This view seems to fit with Russell's 'relational' view of the physical world, though Russell rejected structuralism in mathematics. I take abstraction to be part of perception. |
18617 | Substances, unlike aggregates, can survive a change of parts [Mumford] |
Full Idea: Substances can survive a change in their parts in a way that a mere aggregate of parts. | |
From: Stephen Mumford (Metaphysics: a very short introduction [2012], 3) | |
A reaction: A simple but very important idea. If we then distinguish between 'substances' and 'aggregates' we get a much clearer grip on things. Is the Ship of Theseus a substance or an aggregate? There is no factual answer to that. What do you want to explain? |
10275 | A blurry border is still a border [Shapiro] |
Full Idea: A blurry border is still a border. | |
From: Stewart Shapiro (Philosophy of Mathematics [1997], 8.3) | |
A reaction: This remark deserves to be quoted in almost every area of philosophy, against those who attack a concept by focusing on its vague edges. Philosophers should focus on central cases, not borderline cases (though the latter may be of interest). |
