9969 | The empty set is the purest abstract object [Jubien] |
Full Idea: The empty set is the pure abstract object par excellence. | |
From: Michael Jubien (Ontology and Mathematical Truth [1977], p.118 n8) | |
A reaction: So a really good PhD on the empty set could crack the whole nature of reality. Get to work, whoever you are! |
7712 | On substances, Leibniz emphasises unity, Spinoza independence, Locke relations to qualities [Lowe] |
Full Idea: Later philosophers emphasised different strands of Aristotle's concept of substances: Leibniz (in his theory of monads) emphasised their unity; Spinoza emphasised their ontological independence; Locke emphasised their role in relation to qualities. | |
From: E.J. Lowe (Locke on Human Understanding [1995], Ch.4) | |
A reaction: Note that this Aristotelian idea had not been jettisoned in the late seventeenth century, unlike other Aristotelianisms. I think it is only with the success of atomism in chemistry that the idea of substance is forced to recede. |
