| 23881 | All thought about values is philosophical, and thought about anything else is not philosophy [Weil] |
| Full Idea: All reflections bearing on the notion of value and on the hierarchy of values is philosophical; all efforts of thought bearing on anything other than value are, if one examines them closely, foreign to philosophy. | |
| From: Simone Weil (Reflections on Value [1941], p.30) | |
| A reaction: If nothing else proves that Weil is a platonist, this does. She, of course, has a transcendent and religious view of values, whereas I just see them as concepts which embody what is important. That said, I'm not far off agreeing with this. |
| 15585 | Later Heidegger sees philosophy as more like poetry than like science [Heidegger, by Polt] |
| Full Idea: In his later work Heidegger came to view philosophy as closer to poetry than to science. | |
| From: report of Martin Heidegger (The Origin of the Work of Art [1935], p.178) by Richard Polt - Heidegger: an introduction 5 'Signs' |
| 23885 | Philosophy aims to change the soul, not to accumulate knowledge [Weil] |
| Full Idea: Philosophy does not consist in accumulating knowledge, as science does, but in changing the whole soul. | |
| From: Simone Weil (Reflections on Value [1941], p.33) | |
| A reaction: I agree, roughly. In the sense that philosophy is a much more personal matter than any pure pursuit of knowledge, such as geology. Though a life in geology could change your soul. Not just any old change, of course…. |
| 23886 | Systems are not unique to each philosopher. The platonist tradition is old and continuous [Weil] |
| Full Idea: People believe that every philosopher has a system that contradicts all the others! But there is a tradition, genuinely philosophical, that is as old as humanity itself. …Plato is the most perfect representative of this tradition. | |
| From: Simone Weil (Reflections on Value [1941], p.33) | |
| A reaction: I see roughly two traditions. If you believe in transcendence you follow Plato, like Simone. If you are a naturalist (like me) you follow Aristotle. A third tradition might be much more sceptical. |
| 23884 | Truth is a value of thought [Weil] |
| Full Idea: Truth is a value of thought. The word 'truth' cannot have any other meaning. | |
| From: Simone Weil (Reflections on Value [1941], p.32) | |
| A reaction: This makes a nice change from truth being a mere predicate. I would call truth the criterion of success in thought, and that counts as a value, so she is right. |
| 18696 | The vagueness of truthmaker claims makes it easier to run anti-realist arguments [Button] |
| Full Idea: The sheer lack of structure demanded by truthmaker theorists means that it is easier to run model-theoretic arguments against them than against correspondence theorists. | |
| From: Tim Button (The Limits of Reason [2013], 02.3) | |
| A reaction: Truthmaking is a vague relation, where correspondence is fairly specific. Model arguments say you can keep the sentences steady, but shuffle around what they refer to. |
| 18701 | The coherence theory says truth is coherence of thoughts, and not about objects [Button] |
| Full Idea: According to the coherence theory of truth, for our thoughts to be true is not for them to be about objects, but only for them to cohere with one another. This is rather terrifying. | |
| From: Tim Button (The Limits of Reason [2013], 14.2) | |
| A reaction: Davidson espoused this view in 1983, but then gave it up. It strikes me as either a daft view of truth, or a denial of truth. The coherence theory of justification, on the other hand, is correct. |
| 18694 | Permutation Theorem: any theory with a decent model has lots of models [Button] |
| Full Idea: The Permutation Theorem says that any theory with a non-trivial model has many distinct isomorphic models with the same domain. | |
| From: Tim Button (The Limits of Reason [2013], 02.1) | |
| A reaction: This may be the most significant claim of model theory, since Putnam has erected an argument for anti-realism on it. See the ideas of Tim Button. |
| 18692 | Realists believe in independent objects, correspondence, and fallibility of all theories [Button] |
| Full Idea: External realists have three principles: Independence - the world is objects that are independent of mind, language and theory; Correspondence - truth involves some correspondence of thoughts and things; Cartesian - an ideal theory might be false. | |
| From: Tim Button (The Limits of Reason [2013], 01.1-3) | |
| A reaction: [compressed; he cites Descartes's Demon for the third] Button is setting these up as targets. I subscribe to all three, in some form or other. Of course, as a theory approaches the success implying it is 'ideal', it becomes highly likely to be accurate. |
| 18693 | Indeterminacy arguments say if a theory can be made true, it has multiple versions [Button] |
| Full Idea: Indeterminacy arguments aim to show that if there is any way to make a theory true, then there are many ways to do so. | |
| From: Tim Button (The Limits of Reason [2013], 02.1) | |
| A reaction: Button says the simplest indeterminacy argument is Putnam's Permutation Argument - that you can shuffle the objects in a formal model, without affecting truth. But do we belief that metaphysics can be settled in this sort of way? |
| 18695 | An ideal theory can't be wholly false, because its consistency implies a true model [Button] |
| Full Idea: If realists think an ideal theory could be false, then the theory is consistent, and hence complete, and hence finitely modellable, and hence it is guaranteed that there is some way to make it true. | |
| From: Tim Button (The Limits of Reason [2013], 02.2) | |
| A reaction: [compressed] This challenges the realists' supposed claim that even the most ideal of theories could possibly be false. Presumably for a theory to be 'ideal' is not all-or-nothing. Are we capable of creating a fully ideal theory? [Löwenheim-Skolem] |
| 18700 | Cartesian scepticism doubts what is true; Kantian scepticism doubts that it is sayable [Button] |
| Full Idea: Cartesian scepticism agonises over whether our beliefs are true or false, whereas Kantian scepticism agonises over how it is even possible for beliefs to be true or false. | |
| From: Tim Button (The Limits of Reason [2013], 07.2) | |
| A reaction: Kant's question is, roughly, 'how can our thoughts succeed in being about the world?' Kantian scepticism is the more drastic, and looks vulnerable to a turning of the tables, but asking how Kantian worries can even be expressed. |
| 18698 | Predictions give the 'content' of theories, which can then be 'equivalent' or 'adequate' [Button] |
| Full Idea: The empirical 'content' of a theory is all its observable predictions. Two theories with the same predictions are empirically 'equivalent'. A theory which gets it all right at this level is empirically 'adequate'. | |
| From: Tim Button (The Limits of Reason [2013], 05.1) |
| 18697 | A sentence's truth conditions are all the situations where it would be true [Button] |
| Full Idea: A sentence's truth conditions comprise an exhaustive list of the situations in which that sentence would be true. | |
| From: Tim Button (The Limits of Reason [2013], 03.4) | |
| A reaction: So to know its meaning you must know those conditions? Compare 'my cat is licking my finger' with 'dramatic events are happening in Ethiopia'. It should take an awful long time to grasp the second sentence. |
| 23882 | Ends, unlike means, cannot be defined, which is why people tend to pursue means [Weil] |
| Full Idea: Everything that can be taken as an end cannot be defined. Means, such as power and money, are easily defined, and that is why people orient themselves exclusively towards the acquisition of means. | |
| From: Simone Weil (Reflections on Value [1941], p.31) | |
| A reaction: Nice, but too neat, because so many activities can be treated either as means or as ends, and often as both. It makes sense that people pursue what is clear to them. |
| 23883 | Minds essentially and always strive towards value [Weil] |
| Full Idea: For the mind essentially and always, in whatever manner it is disposed, strives towards value. | |
| From: Simone Weil (Reflections on Value [1941], p.31) | |
| A reaction: A typically platonist thought. If you accept my view that values identify what is important, the thought is plausible. We might distinguish between what the mind pointlessly entertains, and what it 'strives' for. |
