| 6848 | Humour is practically enacted philosophy [Critchley] |
| Full Idea: Humour, for me, is practically enacted philosophy. | |
| From: Simon Critchley (Interview with Baggini and Stangroom [2001], p.198) | |
| A reaction: This may be overstating it, as the funniest jokes may be the least philosophical, and remarks may be faintly amusing but very profound. Lear and his Fool make up a single worldview together. |
| 6847 | Humour can give a phenomenological account of existence, and point to change [Critchley] |
| Full Idea: Humour provides an oblique phenomenology of ordinary life; it is a way of describing the situation of our existence, and, at its best, it indicates how we might change that situation. | |
| From: Simon Critchley (Interview with Baggini and Stangroom [2001], p.198) | |
| A reaction: The trouble is that this leads us to relentlessly political standup comedians who aren't very funny. Critichley may have a problem with remarks which are very funny precisely because they are so politically incorrect. I sympathise, though. |
| 6844 | Scientism is the view that everything can be explained causally through scientific method [Critchley] |
| Full Idea: Scientism is the belief that all phenomena can be explained through the methodology of the natural sciences, and the belief that, therefore, all phenomena are capable of a causal explanation. | |
| From: Simon Critchley (Interview with Baggini and Stangroom [2001], p.196) | |
| A reaction: He links two ideas together, but I tend to subscribe fully to the second idea, but less fully to the first. Scientific method, if there is such a thing (Idea 6804), may not be the best way to lay bare the causal network of reality. |
| 6835 | German idealism aimed to find a unifying principle for Kant's various dualisms [Critchley] |
| Full Idea: In his Third Critique Kant established a series of dualisms (pure/practical reason, nature/freedom, epistemology/ethics) but failed to provide a unifying principle; German idealism can be seen as an attempt to provide this principle. | |
| From: Simon Critchley (Interview with Baggini and Stangroom [2001], p.187) | |
| A reaction: He cites 'subject', 'spirit', 'art', 'will to power', 'praxis' and 'being' as candidates. This is a helpful overview for someone struggling to get to grips with that tradition. |
| 6837 | Since Hegel, continental philosophy has been linked with social and historical enquiry. [Critchley] |
| Full Idea: In continental philosophy from Hegel onwards, systematic philosophical questions have to be linked to socio-historical enquiry, and the distinctions between philosophy, history and society begin to fall apart. | |
| From: Simon Critchley (Interview with Baggini and Stangroom [2001], p.188) | |
| A reaction: I have a strong sales resistance to this view of philosophy, just as I would if it was said about mathematics. It seems to imply a bogus view that history exhibits direction and purpose (the 'Whig' view). There are pure reasons among the prejudices. |
| 6836 | Continental philosophy fights the threatened nihilism in the critique of reason [Critchley] |
| Full Idea: If reason must criticise itself (in Kant) how does one avoid total scepticism? In my view, the problem that has animated the continental tradition since Jacobi (early 19th cent) is the threat of nihilism. | |
| From: Simon Critchley (Interview with Baggini and Stangroom [2001], p.188) | |
| A reaction: As an outsider to 'continental' philosophy, this is the most illuminating remark I have read about it. It is not only a plausible account of the movement, but also a very worth aim, which should be taken seriously by analytical philosophers. |
| 6838 | Continental philosophy is based on critique, praxis and emancipation [Critchley] |
| Full Idea: The basic map of the continental tradition can be summarised in three terms: critique, praxis and emancipation. | |
| From: Simon Critchley (Interview with Baggini and Stangroom [2001], p.189) | |
| A reaction: I wince at 'emancipation', which seems to take freedom as of unquestionably high value, instead of being one of the principles up for question in social philosophy. There are more presuppositions in Marxist than in analytical philosophy. |
| 6845 | Continental philosophy has a bad tendency to offer 'one big thing' to explain everything [Critchley] |
| Full Idea: In continental philosophy there is a pernicious tendency to explain everything in terms of 'one big thing', such as the 'death drive' (Freud), 'being' (Heidegger), 'the real' (Lacan), 'power' (Foucault), 'the other' (Levinas), or 'différance' (Derrida). | |
| From: Simon Critchley (Interview with Baggini and Stangroom [2001], p.197) | |
| A reaction: From a fan of this type of philosophy, this is a refreshing remark, because if pinpoints a very off-putting feature. Each of these 'big things' should be up for question, not offered as axiomatic assumptions that explain everything else. |
| 6846 | Phenomenology is a technique of redescription which clarifies our social world [Critchley] |
| Full Idea: Phenomenology (as in the later Husserl) is for me a way of assembling reminders which clarify the social world in which we exist; it is a technique of redescription. | |
| From: Simon Critchley (Interview with Baggini and Stangroom [2001], p.198) | |
| A reaction: I'm not sure if I can identify with this as a target for philosophy, but it is interesting and sound worthy of effort. Critchley offers this as the best strand in 'continental' philosophy, rather than the big explanatory ideas. |
| 9570 | In Field's Platonist view, set theory is false because it asserts existence for non-existent things [Field,H, by Chihara] |
| Full Idea: Field commits himself to a Platonic view of mathematics. The theorems of set theory are held to imply or presuppose the existence of things that don't in fact exist. That is why he believes that these theorems are false. | |
| From: report of Hartry Field (Science without Numbers [1980]) by Charles Chihara - A Structural Account of Mathematics 11.1 | |
| A reaction: I am sympathetic to Field, but this sounds wrong. A response that looks appealing is that maths is hypothetical ('if-thenism') - the truth is in the logical consequences, not in the ontological presuppositions. |
| 10260 | Logical consequence is defined by the impossibility of P and ¬q [Field,H, by Shapiro] |
| Full Idea: Field defines logical consequence by taking the notion of 'logical possibility' as primitive. Hence q is a consequence of P if the conjunction of the items in P with the negation of q is not possible. | |
| From: report of Hartry Field (Science without Numbers [1980]) by Stewart Shapiro - Philosophy of Mathematics 7.2 | |
| A reaction: The question would then be whether it is plausible to take logical possibility as primitive. Presumably only intuition could support it. But then intuition will equally support natural and metaphysical possibilities. |
| 8958 | In Field's version of science, space-time points replace real numbers [Field,H, by Szabó] |
| Full Idea: Field's nominalist version of science develops a version of Newtonian gravitational theory, where no quantifiers range over mathematical entities, and space-time points and regions play the role of surrogates for real numbers. | |
| From: report of Hartry Field (Science without Numbers [1980]) by Zoltán Gendler Szabó - Nominalism 5.1 | |
| A reaction: This seems to be a very artificial contrivance, but Field has launched a programme for rewriting science so that numbers can be omitted. All of this is Field's rebellion against the Indispensability Argument for mathematics. I sympathise. |
| 18221 | 'Metric' axioms uses functions, points and numbers; 'synthetic' axioms give facts about space [Field,H] |
| Full Idea: There are two approaches to axiomatising geometry. The 'metric' approach uses a function which maps a pair of points into the real numbers. The 'synthetic' approach is that of Euclid and Hilbert, which does without real numbers and functions. | |
| From: Hartry Field (Science without Numbers [1980], 5) |
| 8757 | The Indispensability Argument is the only serious ground for the existence of mathematical entities [Field,H] |
| Full Idea: There is one and only one serious argument for the existence of mathematical entities, and that is the Indispensability Argument of Putnam and Quine. | |
| From: Hartry Field (Science without Numbers [1980], p.5), quoted by Stewart Shapiro - Thinking About Mathematics 9.1 | |
| A reaction: Personally I don't believe (and nor does Field) that this gives a good enough reason to believe in such things. Quine (who likes 'desert landscapes' in ontology) ends up believing that sets are real because of his argument. Not for me. |
| 18212 | Nominalists try to only refer to physical objects, or language, or mental constructions [Field,H] |
| Full Idea: The most popular approach of nominalistically inclined philosophers is to try to reinterpret mathematics, so that its terms and quantifiers only make reference to, say, physical objects, or linguistic expressions, or mental constructions. | |
| From: Hartry Field (Science without Numbers [1980], Prelim) | |
| A reaction: I am keen on naturalism and empiricism, but only referring to physical objects is a non-starter. I think I favour constructions, derived from the experience of patterns, and abstracted, idealised and generalised. Field says application is the problem. |
| 10261 | The application of mathematics only needs its possibility, not its truth [Field,H, by Shapiro] |
| Full Idea: Field argues that to account for the applicability of mathematics, we need to assume little more than the possibility of the mathematics, not its truth. | |
| From: report of Hartry Field (Science without Numbers [1980]) by Stewart Shapiro - Philosophy of Mathematics 7.2 | |
| A reaction: Very persuasive. We can apply chess to real military situations, provided that chess isn't self-contradictory (or even naturally impossible?). |
| 18218 | Hilbert explains geometry, by non-numerical facts about space [Field,H] |
| Full Idea: Facts about geometric laws receive satisfying explanations, by the intrinsic facts about physical space, i.e. those laid down without reference to numbers in Hilbert's axioms. | |
| From: Hartry Field (Science without Numbers [1980], 3) | |
| A reaction: Hilbert's axioms mention points, betweenness, segment-congruence and angle-congruence (Field 25-26). Field cites arithmetic and geometry (as well as Newtonian mechanics) as not being dependent on number. |
| 9623 | Field needs a semantical notion of second-order consequence, and that needs sets [Brown,JR on Field,H] |
| Full Idea: Field needs the notion of logical consequence in second-order logic, but (since this is not recursively axiomatizable) this is a semantical notion, which involves the idea of 'true in all models', a set-theoretic idea if there ever was one. | |
| From: comment on Hartry Field (Science without Numbers [1980], Ch.4) by James Robert Brown - Philosophy of Mathematics | |
| A reaction: Brown here summarises a group of critics. Field was arguing for modern nominalism, that actual numbers could (in principle) be written out of the story, as useful fictions. Popper's attempt to dump induction seemed to need induction. |
| 18215 | It seems impossible to explain the idea that the conclusion is contained in the premises [Field,H] |
| Full Idea: No clear explanation of the idea that the conclusion was 'implicitly contained in' the premises was ever given, and I do not believe that any clear explanation is possible. | |
| From: Hartry Field (Science without Numbers [1980], 1) |
| 18216 | Abstractions can form useful counterparts to concrete statements [Field,H] |
| Full Idea: Abstract entities are useful because we can use them to formulate abstract counterparts of concrete statements. | |
| From: Hartry Field (Science without Numbers [1980], 3) | |
| A reaction: He defends the abstract statements as short cuts. If the concrete statements were 'true', then it seems likely that the abstract counterparts will also be true, which is not what fictionalism claims. |
| 18214 | Mathematics is only empirical as regards which theory is useful [Field,H] |
| Full Idea: Mathematics is in a sense empirical, but only in the rather Pickwickian sense that is an empirical question as to which mathematical theory is useful. | |
| From: Hartry Field (Science without Numbers [1980], 1) | |
| A reaction: Field wants mathematics to be fictions, and not to be truths. But can he give an account of 'useful' that does not imply truth? Only in a rather dubiously pragmatist way. A novel is not useful. |
| 18210 | Why regard standard mathematics as truths, rather than as interesting fictions? [Field,H] |
| Full Idea: Why regard the axioms of standard mathematics as truths, rather than as fictions that for a variety of reasons mathematicians have become interested in? | |
| From: Hartry Field (Science without Numbers [1980], p.viii) |
| 18211 | You can reduce ontological commitment by expanding the logic [Field,H] |
| Full Idea: One can often reduce one's ontological commitments by expanding one's logic. | |
| From: Hartry Field (Science without Numbers [1980], p.ix) | |
| A reaction: I don't actually understand this idea, but that's never stopped me before. Clearly, this sounds like an extremely interesting thought, and hence I should aspire to understand it. So I do aspire to understand it. First, how do you 'expand' a logic? |
| 8959 | Field presumes properties can be eliminated from science [Field,H, by Szabó] |
| Full Idea: Field regards the eliminability of apparent reference to properties from the language of science as a foregone result. | |
| From: report of Hartry Field (Science without Numbers [1980]) by Zoltán Gendler Szabó - Nominalism 5.1 n50 | |
| A reaction: Field is a nominalist who also denies the existence of mathematics as part of science. He has a taste for ontological 'desert landscapes'. I have no idea what a property really is, so I think he is on to something. |
| 18213 | Abstract objects are only applicable to the world if they are impure, and connect to the physical [Field,H] |
| Full Idea: To be able to apply any postulated abstract entities to the physical world, we need impure abstact entities, e.g. functions that map physical objects into pure abstract objects. | |
| From: Hartry Field (Science without Numbers [1980], 1) | |
| A reaction: I am a fan of 'impure metaphysics', and this pinpoints my reason very nicely. |
| 19347 | Substance needs independence, unity, and stability (for individuation); also it is a subject, for predicates [Perkins] |
| Full Idea: For individuation, substance needs three properties: independence, to separate it from other things; unity, to call it one thing, rather than an aggregate; and permanence or stability over time. Its other role is as subject for predicates. | |
| From: Franklin Perkins (Leibniz: Guide for the Perplexed [2007], 3.1) | |
| A reaction: Perkins is describing the Aristotelian view, which is taken up by Leibniz. 'Substance' is not a controversial idea, if we see that it only means that the world is full of 'things'. It is an unusual philosopher wholly totally denies that. |
| 18222 | Beneath every extrinsic explanation there is an intrinsic explanation [Field,H] |
| Full Idea: A plausible methodological principle is that underlying every good extrinsic explanation there is an intrinsic explanation. | |
| From: Hartry Field (Science without Numbers [1980], 5) | |
| A reaction: I'm thinking that Hartry Field is an Aristotelian essentialist, though I bet he would never admit it. |
| 9917 | 'Abstract' is unclear, but numbers, functions and sets are clearly abstract [Field,H] |
| Full Idea: The term 'abstract entities' may not be entirely clear, but one thing that does seem clear is that such alleged entities as numbers, functions and sets are abstract. | |
| From: Hartry Field (Science without Numbers [1980], p.1), quoted by JP Burgess / G Rosen - A Subject with No Object I.A.1.a | |
| A reaction: Field firmly denies the existence of such things. Sets don't seem a great problem, if the set is a herd of elephants, but the null and singleton sets show up the difficulties. |
| 6843 | Perceiving meaninglessness is an achievement, which can transform daily life [Critchley] |
| Full Idea: If nihilism is the threat of the collapse of meaning, then my position is that one has to accept meaninglessness as an achievement, as an accomplishment that permits a transformed relation to everyday life. | |
| From: Simon Critchley (Interview with Baggini and Stangroom [2001], p.193) | |
| A reaction: This sounds cheerfully upbeat and life-enhancing, but I don't quite see how it works. One could easily end up laughing at the most appalling tragedies, and that seems to me to be an inappropriate (Aristotelian word) way to respond to tragedy. |
| 18223 | In theories of fields, space-time points or regions are causal agents [Field,H] |
| Full Idea: According to theories that take the notion of a field seriously, space-time points or regions are fully-fledge causal agents. | |
| From: Hartry Field (Science without Numbers [1980], n 23) |
| 18220 | Both philosophy and physics now make substantivalism more attractive [Field,H] |
| Full Idea: In general, it seems to me that recent developments in both philosophy and physics have made substantivalism a much more attractive position than it once was. | |
| From: Hartry Field (Science without Numbers [1980], 4) | |
| A reaction: I'm intrigued as to what philosophical developments are involved in this. The arrival of fields is the development in physics. |
| 18219 | Relational space is problematic if you take the idea of a field seriously [Field,H] |
| Full Idea: The problem of the relational view of space is especially acute in the context of physical theories that take the notion of a field seriously, e.g. classical electromagnetic theory. | |
| From: Hartry Field (Science without Numbers [1980], 4) | |
| A reaction: In the Leibniz-Clarke debate I sided with the Newtonian Clarke (defending absolute space), and it looks like modern science agrees with me. Nothing exists purely as relations. |
