10 ideas
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) |
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. |
8349 | The best way to do ontology is to make sense of our normal talk [Davidson] |
Full Idea: I do not know any better way of showing what there is than looking at the assumptions needed to make sense of our normal talk. | |
From: Donald Davidson (Causal Relations [1967], §4) | |
A reaction: Davidson was a pupil of Quine. This I take to be the last flowering of twentieth century linguistic philosophy. The ontology we deduce from talk in a children's playground might be very bizarre, but we are unlikely to endorse it. 'Honest, it's true!' |
18091 | Infinitesimals are ghosts of departed quantities [Berkeley] |
Full Idea: The infinitesimals are the ghosts of departed quantities. | |
From: George Berkeley (The Analyst [1734]), quoted by David Bostock - Philosophy of Mathematics 4.3 | |
A reaction: [A famous phrase, but as yet no context for it] |
8348 | If we don't assume that events exist, we cannot make sense of our common talk [Davidson] |
Full Idea: The assumption, ontological and metaphysical, that there are events, is one without which we cannot make sense of much of our most common talk. | |
From: Donald Davidson (Causal Relations [1967], §4) | |
A reaction: He considers events to be unanalysable basics. Explanation of normal talk also needs ghosts, premonitions, telepathy and Father Christmas. It is extremely hard to individuate events, unless they are subatomic, and rather numerous. |
8347 | Explanations typically relate statements, not events [Davidson] |
Full Idea: Explanations typically relate statements, not events. | |
From: Donald Davidson (Causal Relations [1967], §4) | |
A reaction: An oddly linguistic way of putting our attempts to understand the world. Presumably the statements are supposed to be about the events (or whatever), and they are supposed to be true, so we are trying to relate features of the world. |
10371 | Distinguish causation, which is in the world, from explanations, which depend on descriptions [Davidson, by Schaffer,J] |
Full Idea: Davidson distinguishes between causation, an extensional relation that holds between coarse events, and explanation, which is an intensional relation that holds between the coarse events under a description. | |
From: report of Donald Davidson (Causal Relations [1967]) by Jonathan Schaffer - The Metaphysics of Causation 1.2 | |
A reaction: I'm unclear why everything has to be so coarse, when reality and causal events seem to fine-grained, but the distinction strikes me as good. Explanations relate to human understanding and human interests. Cf. Anscombe's view. |
8403 | Either facts, or highly unspecific events, serve better as causes than concrete events [Field,H on Davidson] |
Full Idea: It is best to avoid Davidson's view that only quite concrete events can serve as causes; we should either say that facts as well as events can serve as causes; or that the events can be highly unspecific, including 'omissions'. | |
From: comment on Donald Davidson (Causal Relations [1967]) by Hartry Field - Causation in a Physical World 1 | |
A reaction: Something NOT happening might be the main cause of an effect (drought), or an effect may mainly result from a situation rather than an event (famine). |
8346 | Full descriptions can demonstrate sufficiency of cause, but not necessity [Davidson] |
Full Idea: The fuller we make the description of a cause, the better our chances of demonstrating that it was sufficient (as described) to produce the effect, and the worse our chances of demonstrating that it was necessary. (For the effect, it is the opposite). | |
From: Donald Davidson (Causal Relations [1967], §3) | |
A reaction: If the fullness of description is relevant, this suggests that Davidson is focusing on human explanations, rather than on the ontology of causation. If the cause IS necessary, why wouldn't a better description make that clearer? |
4778 | A singular causal statement is true if it is held to fall under a law [Davidson, by Psillos] |
Full Idea: For Davidson, what makes singular causal statements true is the existence of some regularities or laws. All causal is nomological: c causes e iff there is a law that connects events like c with events like e. | |
From: report of Donald Davidson (Causal Relations [1967]) by Stathis Psillos - Causation and Explanation §2.6 | |
A reaction: I wonder if the cart is before the horse here. Scriven says this is just a claim that there are "phantom laws". It is the Humean view of causation, but surely the laws come after the causation, so can't be used to explain it? |
