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) |
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) |
527 | Everything exists which anyone perceives [Metrodorus of Chios] |
Full Idea: Everything exists which anyone perceives. | |
From: Metrodorus (Chi) (Natural Science (lost) [c.340 BCE], B2), quoted by (who?) - where? | |
A reaction: cf Berkeley and Epicurus. This misses out the problem of perceptual error, such as a square tower looking round from a distance, or one person in a group thinking they have seen something. It is still a good criterion, though! |
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) |
15990 | Every individual thing which exists has an essence, which is its internal constitution [Locke] |
Full Idea: I take essences to be in everything that internal constitution or frame for the modification of substance, which God in his wisdom gives to every particular creature, when he gives it a being; and such essences I grant there are in all things that exist. | |
From: John Locke (Letters to Edward Stillingfleet [1695], Letter 1), quoted by Simon Blackburn - Quasi-Realism no Fictionalism | |
A reaction: This is the clearest statement I have found of Locke's commitment to essences, for all his doubts about whether we can know such things. Alexander says (ch.13) Locke was reacting against scholastic essence, as pertaining to species. |
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) |
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) |
15994 | If it is knowledge, it is certain; if it isn't certain, it isn't knowledge [Locke] |
Full Idea: What reaches to knowledge, I think may be called certainty; and what comes short of certainty, I think cannot be knowledge. | |
From: John Locke (Letters to Edward Stillingfleet [1695], Letter 2), quoted by Simon Blackburn - Quasi-Realism no Fictionalism | |
A reaction: I much prefer that fallibilist approach offered by the pragmatists. Knowledge is well-supported belief which seems (and is agreed) to be true, but there is a small shadow of doubt hanging over all of it. |
