19044 | Saying truths fit experience adds nothing to truth; nothing makes sentences true [Davidson] |
Full Idea: The notion of fitting the totality of experience ...adds nothing intelligible to the simple concept of being true. ....Nothing, ...no thing, makes sentences and theories true: not experience, not surface irritations, not the world. | |
From: Donald Davidson (The Very Idea of a Conceptual Scheme [1974], p.11), quoted by Willard Quine - On the Very Idea of a Third Dogma p.39 | |
A reaction: If you don't have a concept of what normally makes a sentence true, I don't see how you go about distinguishing what is true from what is false. You can't just examine the sentence to see if it has the 'primitive' property of truth. Holism is involved.... |
19419 | Not all of perception is accompanied by consciousness [Leibniz] |
Full Idea: I do not think that the Cartesians have ever proved or can prove that every perception is accompanied by consciousness. | |
From: Gottfried Leibniz (Principle of Life and Plastic Natures [1705], p.195) | |
A reaction: This idea is very important in Leibniz, because non-conscious or barely conscious thoughts and perceptions explain a huge amount about behaviour, reality and morality. |
6400 | Without the dualism of scheme and content, not much is left of empiricism [Davidson] |
Full Idea: The third dogma of empiricism is the dualism of scheme and content, of organizing system and something waiting to be organized, which cannot be made intelligible and defensible. If we give it up, it is not clear that any distinctive empiricism remains. | |
From: Donald Davidson (The Very Idea of a Conceptual Scheme [1974], p.189) | |
A reaction: The first two dogmas were 'analyticity' and 'reductionism', as identified by Quine in 1953. Presumably Hume's Principles of Association (Idea 2189) would be an example of a scheme. A key issue is whether there is any 'pure' content. |
6398 | Different points of view make sense, but they must be plotted on a common background [Davidson] |
Full Idea: Different points of view make sense, but only if there is a common co-ordinate system on which to plot them. | |
From: Donald Davidson (The Very Idea of a Conceptual Scheme [1974], p.184) | |
A reaction: This seems right to me. I am very struck by the close similarities between people from wildly differing cultural backgrounds, as seen, for example, at the Olympic Games. |
19421 | Souls act as if there were no bodies, and bodies act as if there were no souls [Leibniz] |
Full Idea: Everything takes place in souls as if there were no body, and everything takes place in bodies as if there were no souls. | |
From: Gottfried Leibniz (Principle of Life and Plastic Natures [1705], p.198) | |
A reaction: I don't think I have ever encountered a modern thinker who accepts this view. Leibniz rejected Occasionalism, but his account depends entirely on the role of God, to set up the pre-established harmony. Why would God do that? |
6399 | Criteria of translation give us the identity of conceptual schemes [Davidson] |
Full Idea: Studying the criteria of translation is a way of focusing on criteria of identity for conceptual schemes. | |
From: Donald Davidson (The Very Idea of a Conceptual Scheme [1974], p.184) | |
A reaction: This is why it was an inspired idea of Quine's to make translation a central topic in philosophy. We must be cautious, though, about saying that the language is the conceptual scheme, as that leaves animals with no scheme at all. |
468 | Musical performance can reveal a range of virtues [Damon of Ath.] |
Full Idea: In singing and playing the lyre, a boy will be likely to reveal not only courage and moderation, but also justice. | |
From: Damon (fragments/reports [c.460 BCE], B4), quoted by (who?) - where? |
19420 | Death and generation are just transformations of an animal, augmented or diminished [Leibniz] |
Full Idea: Death, like generation, is only the transformation of the same animal, which is sometimes augmented and sometimes diminished. | |
From: Gottfried Leibniz (Principle of Life and Plastic Natures [1705], p.195) | |
A reaction: Leibniz has a very unusual view of death, since neither minds nor their bodies can ever be wholly destroyed. Death is a kind of shrinking. I suspect that he was wrong about that. |
19416 | Not all of matter is animated, any more than a pond full of living fish is animated [Leibniz] |
Full Idea: It must not be said that each portion of matter is animated, just as we do not say that a pond full of fishes is an animated body, although a fish is. | |
From: Gottfried Leibniz (Principle of Life and Plastic Natures [1705], p.190) | |
A reaction: This is a particularly clear picture of the role of monads in matter. Monads are attached to bodies, which are entirely inanimate, but monads suffuse matter and give it its properties, like particularly bubbly champagne. Cf Idea 19422. |
19422 | Every particle of matter contains organic bodies [Leibniz] |
Full Idea: There is no particle of matter which does not contain organic bodies. | |
From: Gottfried Leibniz (Principle of Life and Plastic Natures [1705], p.198) | |
A reaction: Cf Idea 19416. There seems to be an interaction problem here (solved, presumably, by pre-established harmony). The organic bodies are there to explain the active behaviour of matter, but the related matter seems intrinsically inert. |
19418 | Mechanics shows that all motion originates in other motion, so there is a Prime Mover [Leibniz] |
Full Idea: The maxim that there is no motion which has not its origin in another motion, according to the laws of mechanics, leads us again to the Prime Mover. | |
From: Gottfried Leibniz (Principle of Life and Plastic Natures [1705], p.194) | |
A reaction: This is Leibniz's endorsement (uncredited) to Aquinas's First Way. It is hard to see how the laws of mechanics could have anything to say about the origin of movement. And doesn't the law say that the motions of God need a mover? |
19417 | All substances are in harmony, even though separate, so they must have one divine cause [Leibniz] |
Full Idea: My system of Pre-established Harmony furnishes a new proof of God's existence, since it is manifest that the agreement of so many substances, of which the one has no influence upon the other, could only come from a general cause on which they all depend. | |
From: Gottfried Leibniz (Principle of Life and Plastic Natures [1705], p.192) | |
A reaction: Adjacent harmony seems self-explanatory, but remote harmony is interesting evidence for God. Hence modern quantum non-locality should make us all wonder whether there is a deeper explanation. |
