13189 | A necessary feature (such as air for humans) is not therefore part of the essence [Leibniz] |
Full Idea: That which is necessary for something does not constitute its essence. Air is necessary for our life, but our life is something other than air. | |
From: Gottfried Leibniz (Letters to Queen Charlotte [1702], 1702) | |
A reaction: Bravo. Why can't modern philosophers hang on to this distinction? They seem to think that because they don't believe in traditional essences they can purloin the word for something else. Same with the word 'abstraction'. |
23018 | How does a changing object retain identity or have incompatible properties over time? [Baron/Miller] |
Full Idea: The problems of temporary intrinsics are reconciling the indiscernibility of identicals with change in an object over time, and the problem of something have incompatible properties over time (such as tired and not-tired). | |
From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 7.3.1) | |
A reaction: Loosely speaking, I would offer some sort of essentialism as the answer to these problems. People are not essentially sitting down, or tired. Or we can relativise properties to times t1 and t2. |
