| 19672 | Kant fails to prove the necessity of laws, because his reasoning about chance is over-ambitious [Meillassoux on Kant] |
| 17736 | We can't learn of space through experience; experience of space needs its representation [Kant] |

| 8451 | Existence is merely derived from the word 'is' (rather than being a predicate) [Kant, by Orenstein] |
| 3321 | Modern logic says (with Kant) that existence is not a predicate, because it has been reclassified as a quantifier [Benardete,JA on Kant] |
| 13732 | Kant never denied that 'exist' could be a predicate - only that it didn't enlarge concepts [Kant, by Fitting/Mendelsohn] |
| 5609 | If 'this exists' is analytic, either the thing is a thought, or you have presupposed its existence [Kant] |
| 5608 | Is "This thing exists" analytic or synthetic? [Kant] |
| 5610 | If an existential proposition is synthetic, you must be able to cancel its predicate without contradiction [Kant] |
