| 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. |
| 3745 | Must sentences make statements to qualify for truth? [O'Connor] |
| Full Idea: Maybe a sentence is not a candidate for truth until it is used to make a statement. | |
| From: D.J. O'Connor (The Correspondence Theory of Truth [1975], Ch.6) |
| 3742 | Beliefs must match facts, but also words must match beliefs [O'Connor] |
| Full Idea: Our beliefs must claim a correspondence with facts, and then the verbal expression of the belief must correspond to the belief itself. | |
| From: D.J. O'Connor (The Correspondence Theory of Truth [1975], Ch.4) |
| 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. |
| 3744 | The semantic theory requires sentences as truth-bearers, not propositions [O'Connor] |
| Full Idea: The Semantic Theory of truth requires that sentences are truth-bearers (rather than statements, or propositions). | |
| From: D.J. O'Connor (The Correspondence Theory of Truth [1975], Ch.6) |
| 3749 | What does 'true in English' mean? [O'Connor] |
| Full Idea: We do not seem to have any use in ordinary discourse for phrases like 'true in English', 'false in German'. | |
| From: D.J. O'Connor (The Correspondence Theory of Truth [1975], II.1) |
| 3746 | Logic seems to work for unasserted sentences [O'Connor] |
| Full Idea: If sentences can have truth-values only when they occur as asserted, it would be impossible to have a truth-functional basis to logic. | |
| From: D.J. O'Connor (The Correspondence Theory of Truth [1975], Ch.6) |
| 3747 | Events are fast changes which are of interest to us [O'Connor] |
| Full Idea: The standard cases of events are physical changes which happen sufficiently fast to be observed as changes, and which are of sufficient interest to us to be noticed or commented on. | |
| From: D.J. O'Connor (The Correspondence Theory of Truth [1975], Ch.7) |
| 23647 | Objects have an essential constitution, producing its qualities, which we are too ignorant to define [Reid] |
| Full Idea: Individuals and objects have a real essence, or constitution of nature, from which all their qualities flow: but this essence our faculties do not comprehend. They are therefore incapable of definition. | |
| From: Thomas Reid (Essays on Intellectual Powers 4: Conception [1785], 1) | |
| A reaction: Aha - he's one of us! I prefer the phrase 'essential nature' of an object, which is understood, I think, by everyone. I especially like the last bit, directed at those who mistakenly think that Aristotle identified the essence with the definition. |
| 11958 | Impossibilites are easily conceived in mathematics and geometry [Reid, by Molnar] |
| Full Idea: Reid pointed out how easily conceivable mathematical and geometric impossibilities are. | |
| From: report of Thomas Reid (Essays on Intellectual Powers 4: Conception [1785], IV.III) by George Molnar - Powers 11.3 | |
| A reaction: The defence would be that you have to really really conceive them, and the only way the impossible can be conceived is by blurring it at the crucial point, or by claiming to conceive more than you actually can |
| 3748 | Without language our beliefs are particular and present [O'Connor] |
| Full Idea: Without language we would be restricted to particular beliefs about the here and now. | |
| From: D.J. O'Connor (The Correspondence Theory of Truth [1975], Ch.8) |
| 3743 | We can't contemplate our beliefs until we have expressed them [O'Connor] |
| Full Idea: It is only when beliefs are given some symbolic expression that they acquire the precision and stability that enables us to entertain them. | |
| From: D.J. O'Connor (The Correspondence Theory of Truth [1975], Ch.5) |
| 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. |
| 23646 | Reference is by name, or a term-plus-circumstance, or ostensively, or by description [Reid] |
| Full Idea: An individual is expressed by a proper name, or by a general word joined to distinguishing circumstances; if unknown, it may be pointed out to the senses; when beyond the reach of the senses it may be picked out by an imperfect but true description. | |
| From: Thomas Reid (Essays on Intellectual Powers 4: Conception [1785], 1) | |
| A reaction: [compressed] If Putnam, Kripke and Donnellan had read this paragraph they could have save themselves a lot of work! I take reference to be the activity of speakers and writers, and these are the main tools of the trade. |
| 23645 | A word's meaning is the thing conceived, as fixed by linguistic experts [Reid] |
| Full Idea: The meaning of a word (such as 'felony') is the thing conceived; and that meaning is the conception affixed to it by those who best understand the language. | |
| From: Thomas Reid (Essays on Intellectual Powers 4: Conception [1785], 1) | |
| A reaction: He means legal experts. This is precisely that same as Putnam's account of the meaning of 'elm tree'. His discussion here of reference is the earliest I have encountered, and it is good common sense (for which Reid is famous). |
