| 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. |
| 8952 | We reach 'reflective equilibrium' when intuitions and theory completely align [Fisher] |
| Full Idea: A state of 'reflective equilibrium' is when our theory and our intuitions become completely aligned | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 12.IV) | |
| A reaction: [Rawls made this concept famous] This is a helpful concept in trying to spell out the ideal which is the dream of believers in 'pure reason' - that there is a goal in which everything comes right. The problem is when people have different intuitions! |
| 8943 | Three-valued logic says excluded middle and non-contradition are not tautologies [Fisher] |
| Full Idea: In three-valued logic (L3), neither the law of excluded middle (p or not-p), nor the law of non-contradiction (not(p and not-p)) will be tautologies. If p has the value 'indeterminate' then so will not-p. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 07.I) | |
| A reaction: I quite accept that the world is full of indeterminate propositions, and that excluded middle and non-contradiction can sometimes be uncertain, but I am reluctant to accept that what is being offered here should be called 'logic'. |
| 8945 | Fuzzy logic has many truth values, ranging in fractions from 0 to 1 [Fisher] |
| Full Idea: In fuzzy logic objects have properties to a greater or lesser degree, and truth values are given as fractions or decimals, ranging from 0 to 1. Not-p is defined as 1-p, and other formula are defined in terms of maxima and minima for sets. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 07.II) | |
| A reaction: The question seems to be whether this is actually logic, or a recasting of probability theory. Susan Haack attacks it. If logic is the study of how truth is preserved as we move between propositions, then 0 and 1 need a special status. |
| 8951 | Classical logic is: excluded middle, non-contradiction, contradictions imply all, disjunctive syllogism [Fisher] |
| Full Idea: For simplicity, we can say that 'classical logic' amounts to the truth of four sentences: 1) either p or not-p; 2) it is not the case that both p and not-p; 3) from p and not-p, infer q; 4) from p or q and not-p, infer q. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 12.I) | |
| A reaction: [She says there are many ways of specifying classical logic] Intuition suggests that 2 and 4 are rather hard to dispute, while 1 is ignoring some grey areas, and 3 is totally ridiculous. There is, of course, plenty of support for 3! |
| 8950 | Logic formalizes how we should reason, but it shouldn't determine whether we are realists [Fisher] |
| Full Idea: Even if one is inclined to be a realist about everything, it is hard to see why our logic should be the determiner. Logic is supposed to formalize how we ought to reason, but whether or not we should be realists is a matter of philosophy, not logic. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 09.I) | |
| A reaction: Nice to hear a logician saying this. I do not see why talk in terms of an object is a commitment to its existence. We can discuss the philosopher's stone, or Arthur's sword, or the Loch Ness monster, or gravitinos, with degrees of commitment. |
| 8946 | We could make our intuitions about heaps precise with a million-valued logic [Fisher] |
| Full Idea: We could construct a 1,000,000-valued logic that would allow our intuitions concerning a heap to vary exactly with the amount of sand in the heap. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008]) | |
| A reaction: Presumably only an infinite number of grains of sand would then produce a true heap, and even one grain would count as a bit of a heap, which must both be wrong, so I can't see this helping much. |
| 8944 | Vagueness can involve components (like baldness), or not (like boredom) [Fisher] |
| Full Idea: Vague terms come in at least two different kinds: those whose constituent parts come in discrete packets (bald, rich, red) and those that don't (beauty, boredom, niceness). | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 07.II) | |
| A reaction: The first group seem to be features of the external world, and the second all occur in the mind. Baldness may be vague, but presumably hairs are (on the whole) not. Nature doesn't care whether someone is actually 'bald' or not. |
| 8941 | We can't explain 'possibility' in terms of 'possible' worlds [Fisher] |
| Full Idea: Explaining 'it is possible that p' by saying p is true in at least one possible world doesn't get me very far. If I don't understand what possibility is, then appealing to possible worlds is not going to do me much good. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 06.III) | |
| A reaction: This seems so blatant that I assume friends of possible worlds will have addressed the problem. Note that you will also need to understand 'possible' to define necessity as 'true in all possible worlds'. Necessarily-p is not-possibly-not-p. |
| 8947 | If all truths are implied by a falsehood, then not-p might imply both q and not-q [Fisher] |
| Full Idea: If all truths are implied by a falsehood, then 'if there are no trees in the park then there is no shade' and 'if there are no trees in the park there is plenty of shade' both come out as true. Intuitively, though, the second one is false. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 08.I) | |
| A reaction: The rule that a falsehood implies all truths must be the weakest idea in classical logic, if it actually implies a contradiction. This means we must take an interest in relevance logics. |
| 8949 | In relevance logic, conditionals help information to flow from antecedent to consequent [Fisher] |
| Full Idea: A good account of relevance logic suggests that a conditional will be true when the flow of information is such that a conditional is the device that helps information to flow from the antecedent to the consequent. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 08.III) | |
| A reaction: Hm. 'If you are going out, you'll need an umbrella'. This passes on information about 'out', but also brings in new information. 'If you are going out, I'm leaving you'. What flows is an interpretation of the antecedent. Tricky. |
| 21687 | It seems obvious to prefer the simpler of two theories, on grounds of beauty and convenience [Quine] |
| Full Idea: It is not to be wondered that theory makers seek simplicity. When two theories are equally defensible on other counts, certainly the simpler of the two is to be preferred on the score of both beauty and convenience. | |
| From: Willard Quine (On Simple Theories of a Complex World [1960], p.255) | |
| A reaction: A simple application of Ockham's Razor. Quine goes on to nicely deconstruct what is involved in simplicity, and identify a certain amount of dubious prejudice in the concept. |
| 21688 | There are four suspicious reasons why we prefer simpler theories [Quine] |
| Full Idea: We prefer simpler theories through wishful thinking, or a bias which slants the data, or a bias where the simpler hypothesis is more open to confirmation, or simpler hypotheses tolerating wider deviations in score-keeping. | |
| From: Willard Quine (On Simple Theories of a Complex World [1960], p.258) | |
| A reaction: [a compression of his summary of the paper] Quine is not dismissing our preference for simpler theories, but just very nicely inviting us to focus of aspects about which we should be cautious. |
| 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. |
