| 5969 | Chrysippus said the uncaused is non-existent [Chrysippus, by Plutarch] |
| Full Idea: Chrysippus said that the uncaused is altogether non-existent. | |
| From: report of Chrysippus (fragments/reports [c.240 BCE]) by Plutarch - 70: Stoic Self-contradictions 1045c | |
| A reaction: The difficulty is to see what empirical basis there can be for such a claim, or what argument of any kind other than an intuition. Induction is the obvious answer, but Hume teaches us scepticism about any claim that 'there can be no exceptions'. |
| 5565 | Proof of the principle of sufficient reason cannot be found [Kant] |
| Full Idea: A proof of the principle of sufficient reason has often been sought, but always in vain. | |
| From: Immanuel Kant (Critique of Pure Reason [1781], B265/A217) | |
| A reaction: This might, of course, be because the principle is false. However it is quite a good candidate for an a priori, or even innate, principle of thought in rational beings. Gödel's Theorem suggests why the enterprise of proof would be doomed. |
| 5563 | The principle of sufficient reason is the ground of possible experience in time [Kant] |
| Full Idea: The principle of sufficient reason is the ground of possible experience, namely the objective cognition of appearances with regard to their relation in the successive series of time. | |
| From: Immanuel Kant (Critique of Pure Reason [1781], B246/A201) | |
| A reaction: The argument to this claim from the necessity of succession in time looks unconvincing to me, but the principle of sufficient reason is deeply imbedded in the human mind. However, philosophers seem to feel it more strongly than other people. |
