7990 | Serene wisdom is freedom from ties, and indifference to fortune [Anon (Bhag)] |
Full Idea: Who everywhere is free from all ties, who neither rejoices nor sorrows if fortune is good or is ill, his is a serene wisdom. | |
From: Anon (Bhag) (The Bhagavad Gita [c.500 BCE], 2.57) | |
A reaction: This is very similar to the 'apatheia' of the Stoics, though they are always more committed to rationality. This is quite a good strategy when times are hard, but as a general rule it offers a bogus state of 'wisdom' which is really half way to death. |
7989 | Seek salvation in the wisdom of reason [Anon (Bhag)] |
Full Idea: Seek salvation in the wisdom of reason. | |
From: Anon (Bhag) (The Bhagavad Gita [c.500 BCE], 2.49) | |
A reaction: Quotations like this can usually be counterbalanced in eastern philosophy by wild irrationality, but they certainly felt to tug of reason. Only the Dhaoists seem really opposed to reason (e.g. Idea 7289). |
22664 | I do not care if my trivial beliefs are false, and I have no interest in many truths [Nozick] |
Full Idea: I find that I do not mind at all the thought that I have some false beliefs (of US state capitals), and there are many truths I do not care to know at all (total grains of sand on the beach). | |
From: Robert Nozick (The Nature of Rationality [1993], p.67) | |
A reaction: A useful corrective to anyone who blindly asserts that truth is the supreme human value. I would still be annoyed if someone taught me lies about these two types of truth. |
22665 | Maybe James was depicting the value of truth, and not its nature [Nozick] |
Full Idea: We might see William James's pragmatic view that truth is what works as depicting the value of truth, and not its nature. | |
From: Robert Nozick (The Nature of Rationality [1993], p.68) | |
A reaction: James didn't think that he was doing this. He firmly says that this IS truth, not just the advantages of truth. Another view is that pragmatists are giving a test for truth. |
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. |
7996 | I am all the beauty and goodness of things, says Krishna [Anon (Bhag)] |
Full Idea: I am the beauty of all things beautiful; ...I am the goodness of those who are good, says Krishna. | |
From: Anon (Bhag) (The Bhagavad Gita [c.500 BCE], 10.36) | |
A reaction: Another attempt to annexe everything which is admirable to the nature of God. This sounds strikingly Platonic (c.f. Idea 7992, which seems Aristotelian). One scholar dates the text to 150 BCE. I think there is influence, one way or the other. |
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. |
7995 | In all living beings I am the light of consciousness, says Krishna [Anon (Bhag)] |
Full Idea: In all living beings I am the light of consciousness, says Krishna. | |
From: Anon (Bhag) (The Bhagavad Gita [c.500 BCE], 10.22) | |
A reaction: Everything grand seems to be claimed for God at this stage of culture, but I am not sure how coherent this view is, unless this is pantheism. In what sense could we possibly be Krishna, when none of us (except Arjuna) is aware of it? |
22662 | In the instrumental view of rationality it only concerns means, and not ends [Nozick] |
Full Idea: On the instrumental conception of rationality, it consists in the effective and efficient achievement of goals, ends, and desires. About the goals themselves it has little to say. | |
From: Robert Nozick (The Nature of Rationality [1993], p.64) | |
A reaction: [He quotes Russell 1954 p.viii as expressing this view] A long way from Greek logos, which obviously concerns the rational selection of right ends (for which, presumably, reasons can be given). In practice our ends may never be rational, of course. |
22663 | Rationality is normally said to concern either giving reasons, or reliability [Nozick] |
Full Idea: The two themes permeating the philosophical literature are that rationality is a matter of reasons, or that rationality is a matter of reliability. | |
From: Robert Nozick (The Nature of Rationality [1993], p.64) | |
A reaction: Since a clock can be reliable, I would have thought it concerns reasons. Or an unthinking person could reliably recite truths from memory. There is also the instrumental view of rationality. |
22666 | Is it rational to believe a truth which leads to permanent misery? [Nozick] |
Full Idea: If a mother is presented with convincing evidence that her son has committed a grave crime, but were she to believe it that would make her life thereafter miserable, is it rational for her to believe her son is guilty? | |
From: Robert Nozick (The Nature of Rationality [1993], p.69) | |
A reaction: I assume there is a conflict of rationalities, because there are conflicting ends. Presumably most mothers love the truth, but most of us also aim for happy lives. It is perfectly rational to avoid discovering a horrible family truth. |
22667 | Rationality needs some self-consciousness, to also evaluate how we acquired our reasons [Nozick] |
Full Idea: Rationality involves some degree of self-consciousness. Not only reasons are evaluated, but also the processes by which information arrives, is stored, and recalled. | |
From: Robert Nozick (The Nature of Rationality [1993], p.74) | |
A reaction: I defend the idea that animals have a degree of rationality, because they can make sensible judgements, but I cannot deny this idea. Rationality comes in degrees, and second-level thought is a huge leap forward in degree. |
7999 | All actions come from: body, lower self, perception, means of action, or Fate [Anon (Bhag)] |
Full Idea: Whatever a man does, good or bad, in thought, word or deed, has these five sources of action: the body, the lower 'I am', the means of perception, the means of action, and Fate. | |
From: Anon (Bhag) (The Bhagavad Gita [c.500 BCE], 18.14/15) | |
A reaction: The 'means of action' will presumably take care of anything we haven't thought of! Nothing quite matches the idea of 'the will' here. A twitch from the first, eating from the second, a startled jump from the third, struck by lightning from the fifth. |
7991 | Hate and lust have their roots in man's lower nature [Anon (Bhag)] |
Full Idea: Hate and lust for things of nature have their roots in man's lower nature. | |
From: Anon (Bhag) (The Bhagavad Gita [c.500 BCE], 3.34) | |
A reaction: It seems outmoded now (since Freud) to label parts of human nature as 'higher' and 'lower'. I would defend the distinction, but it is not self-evident. The basis of morality is good citizenship, and parts of our nature are detrimental to that. |
7988 | There is no greater good for a warrior than to fight in a just war [Anon (Bhag)] |
Full Idea: There is no greater good for a warrior than to fight in righteous war. | |
From: Anon (Bhag) (The Bhagavad Gita [c.500 BCE], 2.31) | |
A reaction: What worries me now is not the urging to fight, as long as a good cause can be found, but the idea that someone should see his social role as 'warrior'. The modern 'soldier' is ready to fight, but a traditional 'warrior' is obliged to fight. |
7992 | The visible forms of nature are earth, water, fire, air, ether; mind, reason, and the sense of 'I' [Anon (Bhag)] |
Full Idea: The visible forms of nature are eight: earth, water, fire, air, ether; the mind, reason, and the sense of 'I'. | |
From: Anon (Bhag) (The Bhagavad Gita [c.500 BCE], 7.4) | |
A reaction: Presumably there is an implication that there are also invisible forms. The Bhuddists launched an attack on 'I' as one of the categories. The first five appear to be Aristotle's, which must be of scholarly (and chronological) interest. |
7994 | Everything, including the gods, comes from me, says Krishna [Anon (Bhag)] |
Full Idea: All the gods come from me, says Krishna. ...I am the one source of all | |
From: Anon (Bhag) (The Bhagavad Gita [c.500 BCE], 10.2/8) | |
A reaction: This seems very close to monotheism, and sounds very similar to the position that Zeus seems to occupy in later Greek religion, where he is shading off into a supreme and spiritual entity. |
7993 | Brahman is supreme, Atman his spirit in man, and Karma is the force of creation [Anon (Bhag)] |
Full Idea: Brahman is supreme, the Eternal. Atman is his Spirit in man. Karma is the force of creation, wherefrom all things have their life. | |
From: Anon (Bhag) (The Bhagavad Gita [c.500 BCE], 8.3) | |
A reaction: I can't help wondering how they know all this stuff, but then I'm just a typical product of my culture. We seem to have a trinity here. Who's in charge? Is Atman just a servant? Is Karma totally under the control of Brahman? |
7997 | Only by love can men see me, know me, and come to me, says Krishna [Anon (Bhag)] |
Full Idea: Only by love can men see me, and know me, and come unto me, says Krishna | |
From: Anon (Bhag) (The Bhagavad Gita [c.500 BCE], 11.54) | |
A reaction: There seems to be a paradox here, as it is unclear how you can love Krishna, if you have not already seen him in some way. This is another paradox of fideism - that faith cannot possibly be the first step in a religion, as faith needs a target. |
7998 | The three gates of hell are lust, anger and greed [Anon (Bhag)] |
Full Idea: Three are the gates of this hell, the death of the soul: the gate of lust, the gate of wrath, and the gate of greed. Let a man shun the three. | |
From: Anon (Bhag) (The Bhagavad Gita [c.500 BCE], 16.21) | |
A reaction: Anyone who wishes to procreate, champion justice, and make a living, has to pursue all three. Wisdom consists of pursuing the three appropriately, not in shunning them. How did this bizarre puritanism ever come to grip the human race? |
