18281 | In mathematics everything is algorithm and nothing is meaning [Wittgenstein] |
Full Idea: In mathematics everything is algorithm and nothing is meaning; even when it doesn't look like that because we seem to be using words to talk about mathematical things. | |
From: Ludwig Wittgenstein (Philosophical Grammar [1932], p.468), quoted by J. Alberto Coffa - The Semantic Tradition from Kant to Carnap 13 'Constr' | |
A reaction: I would have thought that an algorithm needs some raw material to work with. This leads to the idea that meaning arises from rules of usage. |
16007 | I assume existence, rather than reasoning towards it [Kierkegaard] |
Full Idea: I always reason from existence, not towards existence. | |
From: Søren Kierkegaard (Philosophical Fragments [1844], p.40) | |
A reaction: Kierkegaard's important premise to help show that theistic proofs for God's existence don't actually prove existence, but develop the content of a conception. [SY] |
16013 | Nothing necessary can come into existence, since it already 'is' [Kierkegaard] |
Full Idea: Can the necessary come into existence? That is a change, and everything that comes into existence demonstrates that it is not necessary. The necessary already 'is'. | |
From: Søren Kierkegaard (Philosophical Fragments [1844], p.74) | |
A reaction: [SY] |
22371 | Determinism threatens free will if actions can be causally traced to external factors [Foot] |
Full Idea: The determinism which worries the defender of free will is that if human action is subject to a universal law of causation, there will be for any action a set of sufficient conditions which can be traced back to factors outside the control of the agent. | |
From: Philippa Foot (Free Will as Involving Determinism [1957], p.63) | |
A reaction: She draws on Russell for this, but neither of them mention whether the causation is physical. Free will seems to imply non-physical causation. |
22372 | Not all actions need motives, but it is irrational to perform troublesome actions with no motive [Foot] |
Full Idea: We do not expect that everything a rational man does should be done with a motive, ...but we do expect a man to have a motive for many things that he does, and would count anyone who constantly performed troublesome actions without a motive as irrational. | |
From: Philippa Foot (Free Will as Involving Determinism [1957], p.66) | |
A reaction: Interestng, because the assessment of whether someone is 'rational' therefore needs a criterion for when a motive seems required and when not. 'Significant' actions need a motive? |
6606 | Consider: "Imagine this butterfly exactly as it is, but ugly instead of beautiful" [Wittgenstein] |
Full Idea: Suppose someone were to say: "Imagine this butterfly exactly as it is, but ugly instead of beautiful"?! | |
From: Ludwig Wittgenstein (Philosophical Grammar [1932], §127), quoted by Robert Fogelin - Walking the Tightrope of Reason | |
A reaction: This reminds us that the concept of supervenience was originally introduced in aesthetics. Beauty is supervenient on physical form. But "Imagine how someone else might look at this butterfly and think it was ugly". |
22373 | People can act out of vanity without being vain, or even vain about this kind of thing [Foot] |
Full Idea: It makes sense to say that a man acts out of vanity on a particular occasion although he is not in general vain, or even vain about this kind of thing. | |
From: Philippa Foot (Free Will as Involving Determinism [1957], p.69) | |
A reaction: Aristotle tells us that virtues and vices are habits, and also have an intellectual component, implying that the person believes in that sort of behaviour. Anyone can have 'a little moment of vanity'. |
