13132 | A snowball's haecceity is the property of being identical with itself [Plantinga, by Westerhoff] |
Full Idea: Plantinga assumes that being identical with that snowball names a property which is that snowball's haecceity. | |
From: report of Alvin Plantinga (De Essentia [1979]) by Jan Westerhoff - Ontological Categories §52 | |
A reaction: Only a philosopher would suggest such a bizarre way of establishing the unique individuality of a given snowball. You could hardly keep track of the snowball with just that criterion. How do you decide whether something has Plantinga's property? |
4869 | Experience does not teach us any essences of things [Spinoza] |
Full Idea: Experience does not teach us any essences of things. | |
From: Baruch de Spinoza (Letters to De Vries [1664], 1664?) | |
A reaction: This, along with Leibniz's claim that experience cannot reveal necessities, may constitute a striking criticism of empiricism, but it invites the obvious reply 'so much the worse for essences'. An essence seems to be a theoretical concept, not a priori. |
