| 20455 | Philosophy really got started as the rival mode of discourse to tragedy [Critchley] |
| Full Idea: The pre-Socratics are interesting, but philosophy really begins in drama; it's a competitive discourse to tragedy. Which is why Plato's 'Republic' excludes the poets: they're the competition; gotta get rid of them. | |
| From: Simon Critchley (Impossible Objects: interviews [2012], 6) | |
| A reaction: That's an interesting and novel perspective. So what was the 'discourse' of tragedy saying, and why did that provoke the new rival? Was it too fatalistic? |
| 2945 | Most philosophers start with reality and then examine knowledge; Descartes put the study of knowledge first [Lehrer] |
| Full Idea: Some philosophers (e.g Plato) begin with an account of reality, and then appended an account of how we can know it, ..but Descartes turned the tables, insisting that we must first decide what we can know. | |
| From: Keith Lehrer (Theory of Knowledge (2nd edn) [2000], I p.2) |
| 20446 | Philosophy begins in disappointment, notably in religion and politics [Critchley] |
| Full Idea: I claim that philosophy begins in disappointment, and there are two forms of disappointment that interest me: religious and political disappointment | |
| From: Simon Critchley (Impossible Objects: interviews [2012], 2) | |
| A reaction: You are only disappointed by reality if you expected something better. To be disappointed by the failures of religion strikes me as rather old-fashioned, which Critchley sort of admits. Given the size and tumult of modern states, politics isn't promising. |
| 2946 | You cannot demand an analysis of a concept without knowing the purpose of the analysis [Lehrer] |
| Full Idea: An analysis is always relative to some objective. It makes no sense to simply demand an analysis of goodness, knowledge, beauty or truth, without some indication of the purpose of the analysis. | |
| From: Keith Lehrer (Theory of Knowledge (2nd edn) [2000], I p.7) | |
| A reaction: Your dismantling of a car will go better if you know what a car is for, but you can still take it apart in ignorance. |
| 20449 | Science gives us an excessively theoretical view of life [Critchley] |
| Full Idea: One of the problems with the scientific worldview is that it leads human beings to have an overwhelmingly theoretical relationship to the world. | |
| From: Simon Critchley (Impossible Objects: interviews [2012], 2) | |
| A reaction: Critchley is defending phenomenology, but this also supports its cousin, existentialism. I keep meeting bright elderly men who have immersed themselves in the study of science, and they seem very remote from the humanist culture I love. |
| 20448 | Phenomenology uncovers and redescribes the pre-theoretical layer of life [Critchley] |
| Full Idea: Phenomenology is a philosophical method that tries to uncover the pre-theoretical layer of human experience and redescribe it. | |
| From: Simon Critchley (Impossible Objects: interviews [2012], 2) | |
| A reaction: I would be delighted if someone could tell me what this means in practice. I have the impression of lots of talk about phenomenology, but not much doing of it. Clearly I must enquire further. |
| 13430 | Infinity: there is an infinity of distinguishable individuals [Ramsey] |
| Full Idea: The Axiom of Infinity means that there are an infinity of distinguishable individuals, which is an empirical proposition. | |
| From: Frank P. Ramsey (The Foundations of Mathematics [1925], §5) | |
| A reaction: The Axiom sounds absurd, as a part of a logical system, but Ramsey ends up defending it. Logical tautologies, which seem to be obviously true, are rendered absurd if they don't refer to any objects, and some of them refer to infinities of objects. |
| 13428 | Reducibility: to every non-elementary function there is an equivalent elementary function [Ramsey] |
| Full Idea: The Axiom of Reducibility asserted that to every non-elementary function there is an equivalent elementary function [note: two functions are equivalent when the same arguments render them both true or both false]. | |
| From: Frank P. Ramsey (The Foundations of Mathematics [1925], §2) | |
| A reaction: Ramsey in the business of showing that this axiom from Russell and Whitehead is not needed. He says that the axiom seems to be needed for induction and for Dedekind cuts. Since the cuts rest on it, and it is weak, Ramsey says it must go. |
| 13427 | Either 'a = b' vacuously names the same thing, or absurdly names different things [Ramsey] |
| Full Idea: In 'a = b' either 'a' and 'b' are names of the same thing, in which case the proposition says nothing, or of different things, in which case it is absurd. In neither case is it an assertion of a fact; it only asserts when a or b are descriptions. | |
| From: Frank P. Ramsey (The Foundations of Mathematics [1925], §1) | |
| A reaction: This is essentially Frege's problem with Hesperus and Phosphorus. How can identities be informative? So 2+2=4 is extensionally vacuous, but informative because they are different descriptions. |
| 13334 | Contradictions are either purely logical or mathematical, or they involved thought and language [Ramsey] |
| Full Idea: Group A consists of contradictions which would occur in a logical or mathematical system, involving terms such as class or number. Group B contradictions are not purely logical, and contain some reference to thought, language or symbolism. | |
| From: Frank P. Ramsey (The Foundations of Mathematics [1925], p.171), quoted by Graham Priest - The Structure of Paradoxes of Self-Reference 1 | |
| A reaction: This has become the orthodox division of all paradoxes, but the division is challenged by Priest (Idea 13373). He suggests that we now realise (post-Tarski?) that language is more involved in logic and mathematics than we thought. |
| 13426 | Formalists neglect content, but the logicists have focused on generalizations, and neglected form [Ramsey] |
| Full Idea: The formalists neglected the content altogether and made mathematics meaningless, but the logicians neglected the form and made mathematics consist of any true generalisations; only by taking account of both sides can we obtain an adequate theory. | |
| From: Frank P. Ramsey (The Foundations of Mathematics [1925], §1) | |
| A reaction: He says mathematics is 'tautological generalizations'. It is a criticism of modern structuralism that it overemphasises form, and fails to pay attention to the meaning of the concepts which stand at the 'nodes' of the structure. |
| 13425 | Formalism is hopeless, because it focuses on propositions and ignores concepts [Ramsey] |
| Full Idea: The hopelessly inadequate formalist theory is, to some extent, the result of considering only the propositions of mathematics and neglecting the analysis of its concepts. | |
| From: Frank P. Ramsey (The Foundations of Mathematics [1925], §1) | |
| A reaction: You'll have to read Ramsey to see how this thought pans out, but it at least gives a pointer to how to go about addressing the question. |
| 22328 | I just confront the evidence, and let it act on me [Ramsey] |
| Full Idea: I can but put the evidence before me, and let it act on my mind. | |
| From: Frank P. Ramsey (The Foundations of Mathematics [1925], p.202), quoted by Michael Potter - The Rise of Analytic Philosophy 1879-1930 70 'Deg' | |
| A reaction: Potter calls this observation 'downbeat', but I am an enthusiastic fan. It is roughly my view of both concept formation and of knowledge. You soak up the world, and respond appropriately. The trick is in the selection of evidence to confront. |
| 22325 | A belief is knowledge if it is true, certain and obtained by a reliable process [Ramsey] |
| Full Idea: I have always said that a belief was knowledge if it was 1) true, ii) certain, iii) obtained by a reliable process. | |
| From: Frank P. Ramsey (The Foundations of Mathematics [1925], p.258), quoted by Michael Potter - The Rise of Analytic Philosophy 1879-1930 66 'Rel' | |
| A reaction: Not sure why it has to be 'certain' as well as 'true'. It seems that 'true' is objective, and 'certain' subjective. I think I know lots of things of which I am not fully certain. Reliabilism long preceded Alvin Goldman. |
| 20454 | Wallace Stevens is the greatest philosophical poet of the twentieth century in English [Critchley] |
| Full Idea: Wallace Stevens is the greatest philosophical poet of the twentieth century in the English language - full stop - in my humble opinion. | |
| From: Simon Critchley (Impossible Objects: interviews [2012], 6) | |
| A reaction: I include this because I tend to agree, and love Stevens. Hear recordings of him reading. I once mentioned Stevens in a conversation with Ted Hughes, and he just shrugged and said Stevens 'wasn't much of a poet'. Wrong. |
| 20456 | Interesting art is always organised around ethical demands [Critchley] |
| Full Idea: I don't think that art can be unethical. I think that interesting art is always ethical. It is organised around ethical demands. | |
| From: Simon Critchley (Impossible Objects: interviews [2012], 8) | |
| A reaction: It is a struggle to make this fit instrumental music. Critchley likes punk rock, so he might not see the problem. How to compare Bachian, Mozart, Beethovenian and Debussyian ethics? Not impossible. |
| 20447 | The problems is not justifying ethics, but motivating it. Why should a self seek its good? [Critchley] |
| Full Idea: The issue is not so much justification as motivation, that in virtue of which the self can be motivated to act on some conception of the good. ...How does a self bind itself to whatever it determines as its good? | |
| From: Simon Critchley (Impossible Objects: interviews [2012], 2) | |
| A reaction: That is a bold and interesting idea about the starting point for ethics. It is always a problem for Aristotle, that he can offer no motivation for the quest for virtue. Contractarians start from existing motivations, but that isn't impressive. |
| 20452 | Anarchism used to be libertarian (especially for sexuality), but now concerns responsibility [Critchley] |
| Full Idea: Anarchism in the 1960s was libertarian and organised around issues of sexual liberation. That moment has passed. People are and should be organising around responsibility. | |
| From: Simon Critchley (Impossible Objects: interviews [2012], 3) | |
| A reaction: So there are two types of anarchism, focused on freedom or on responsibility. An organisation like Greenpeace might represent the latter. |
| 20450 | The state, law, bureaucracy and capital are limitations on life, so I prefer federalist anarchism [Critchley] |
| Full Idea: I begin with the ontological premise that the state is a limitation on human existence. I am against the state, law, bureaucracy, and capital. I see anarchism as the only desirable way of organising, politically. ...Its political form is federalist. | |
| From: Simon Critchley (Impossible Objects: interviews [2012], 3) | |
| A reaction: Hm. Some sympathy, but caution. All systems, even federalist anarchism, are limitations on our lives, so which limitations do we prefer? The law aspires to a calm egalitarian neutrality, which seems promising to me. |
| 20451 | Belief that humans are wicked leads to authoritarian politics [Critchley] |
| Full Idea: If you think human beings are wicked, you turn to an authoritarian conception of politics, the Hobbesian-Machiavellian-Straussian lie. | |
| From: Simon Critchley (Impossible Objects: interviews [2012], 3) | |
| A reaction: Right-wingers also tend to believe in free will, so they can blame and punish. Good people are more inspired by a great leader than bad people are? (Later, Critchley says authoritarians usually believe in original sin). |
