| 24077 | Necessity is thought to require an event, but is only an after-effect of the event [Nietzsche] |
| Full Idea: Necessity is supposed to be the cause of something coming to be: in truth it is often only an effect of what has come to be. | |
| From: Friedrich Nietzsche (The Gay (Joyful) Science [1882], §205) | |
| A reaction: This sounds like an account of the traditional idea of destiny - which sees inevitability in some major event, which was previously unpredictable. |
| 7134 | Something can be irrefutable; that doesn't make it true [Nietzsche] |
| Full Idea: Something can be irrefutable; that doesn't make it true. | |
| From: Friedrich Nietzsche (Writings from Late Notebooks [1887], 34[247]) | |
| A reaction: This is a warning to rationalists who are looking for strategies to demonstrate necessities a priori. |
| 5998 | From the necessity of the past we can infer the impossibility of what never happens [Diod.Cronus, by White,MJ] |
| Full Idea: Diodorus' Master Argument inferred that since what is past (i.e. true in the past) is necessary, and the impossible cannot follow from the possible, that therefore if something neither is nor ever will be the case, then it is impossible. | |
| From: report of Diodorus Cronus (fragments/reports [c.300 BCE]) by Michael J. White - Diodorus Cronus | |
| A reaction: The argument is, apparently, no longer fully clear, but it seems to imply determinism, or at least a rejection of the idea that free will and determinism are compatible. (Epictetus 2.19) |
| 7186 | There are no necessary truths, but something must be held to be true [Nietzsche] |
| Full Idea: What's necessary is that something must be held to be true; not that something is true. | |
| From: Friedrich Nietzsche (Writings from Late Notebooks [1887], 09[38]) | |
| A reaction: This may be right, but it doesn't follow that the truths we label as 'necessary' are the ones that we have to believe, or even that we have to believe that our chosen beliefs are necessary rather than contingent. Why did we pick those beliefs? |
| 4528 | For me, a priori 'truths' are just provisional assumptions [Nietzsche] |
| Full Idea: The most strongly believed a priori 'truths' are for me provisional assumptions (e.g. the law of causality). | |
| From: Friedrich Nietzsche (The Will to Power (notebooks) [1888], §497) | |
| A reaction: The example of causality would fit in with Humean scepticism, but presumably Nietzsche would also apply it to maths and logic, since he is a thorough-going relativist. I cautiously disagree. |
| 20832 | The Master Argument seems to prove that only what will happen is possible [Diod.Cronus, by Epictetus] |
| Full Idea: The Master Argument: these conflict 1) what is past and true is necessary, 2) the impossible does not follow from the possible, 3) something possible neither is nor will be true. Hence only that which is or will be true is possible. | |
| From: report of Diodorus Cronus (fragments/reports [c.300 BCE]) by Epictetus - The Discourses 2.19.1 | |
| A reaction: [Epictetus goes on to discuss views about which of the three should be given up] It is possible there will be a sea fight tomorrow; tomorrow comes, and no sea fight; so there was necessarily no sea fight; so the impossible followed from the possible. |
| 14304 | Conditionals are true when the antecedent is true, and the consequent has to be true [Diod.Cronus] |
| Full Idea: The connected (proposition) is true when it begins with true and neither could nor can end with false. | |
| From: Diodorus Cronus (fragments/reports [c.300 BCE]), quoted by Stephen Mumford - Dispositions 03.4 | |
| A reaction: [Mumford got the quote from Bochenski] This differs from the truth-functional account because it says nothing about when the antecedent is false, which fits in also with the 'supposition' view, where A is presumed. This idea adds necessity. |
