| 4822 | Divine nature makes all existence and operations necessary, and nothing is contingent [Spinoza] |
| Full Idea: All things are conditioned by the necessity of the divine nature, not only to exist, but also to exist and operate in a particular manner, and there is nothing that is contingent. | |
| From: Baruch de Spinoza (The Ethics [1675], I Pr 29) | |
| A reaction: This obviously invites the response of the empiricist: how does he know that? Hume says he can't know it, and Leibniz says he knows it a priori. Traditionally, 'necessary' is the dubious term, but maybe it is 'contingent' which is meaningless. |
| 17182 | Necessity is in reference to essence or to cause [Spinoza] |
| Full Idea: A thing is called necessary either in reference to its essence or its cause. | |
| From: Baruch de Spinoza (The Ethics [1675], I Pr 33) | |
| A reaction: I like any proposal that necessity should be 'in reference to' something, rather than being free-standing. I like to add necessary 'for' something, which is often conceptual necessity. Roots are necessary for trees. |
