4807 | A good barometer will predict a storm, but not explain it [Psillos] |
Full Idea: There can be predictions without explanations, as when a barometer successfully predicts storms, but on its own it does not explain them. | |
From: Stathis Psillos (Causation and Explanation [2002], §8.8) | |
A reaction: Actually, barometers contribute to explanations. A reasonable predictor might offer no explanation ('if he's out, she's probably out too'), but an infallible predictor is almost certain to involve causation, which helps a lot in explanation. |
4808 | If we say where Mars was two months ago, we offer an explanation without a prediction [Psillos] |
Full Idea: There can be explanations without predictions, as when we explain a previous position of Mars from its present one, plus a law. | |
From: Stathis Psillos (Causation and Explanation [2002], §8.9) | |
A reaction: If we don't mind stretching the word, I think we can 'predict' the past, as where I predict the location of an Egyptian tomb from my study of papyruses. |
4811 | Induction (unlike deduction) is non-monotonic - it can be invalidated by new premises [Psillos] |
Full Idea: Unlike deductive arguments, induction is non-monotonic - that is, it can be invalidated by the addition of new premises. | |
From: Stathis Psillos (Causation and Explanation [2002], §9.2.1) | |
A reaction: This is a fancy way of stating the obvious, which is that induction is not a type of deduction. Hume is sometimes accused of this false assumption. Presumably induction is rational, even if it is not actually logical. |
4812 | Explanation is either showing predictability, or showing necessity, or showing causal relations [Psillos] |
Full Idea: The three types of explanation are 'epistemic' (the event is expectable because of a law), or 'modal' (the event is necessary because of a law), or 'ontic' (it is shown how the event fits into the world's causal structure). | |
From: Stathis Psillos (Causation and Explanation [2002], §11.1) | |
A reaction: Prediction, necessity or causes. It is hard to think of any other way to explain something. Presumably you would exclude necessities if you didn't believe in them. Hume would go for prediction, on the basis of regularities. Personally, I want it all. |
4802 | Just citing a cause does not enable us to understand an event; we also need a relevant law [Psillos] |
Full Idea: Explanation has to do with understanding; just citing a cause would not offer an adequate understanding, unless it was accompanied by the citation of a law that connects the two events. | |
From: Stathis Psillos (Causation and Explanation [2002], §8.2) | |
A reaction: It is surely undeniable that being told the cause but not the law will increase our understanding. Understanding and explanation come in degrees. Full understanding would require an explanation of the law, and beyond. Any relevant truth helps. |
4804 | The 'covering law model' says only laws can explain the occurrence of single events [Psillos] |
Full Idea: The 'deductive-nomological' model became known as the 'covering law model': its main thesis is that laws and only laws adequately explain the occurrence of singular events. | |
From: Stathis Psillos (Causation and Explanation [2002], §8.2) | |
A reaction: But presumably you need other events to derive a law, so you could say that a singular event can only be explained if it isn't singular. A regularity pattern would offer a partial explanation, before any law had been derived. |
4805 | If laws explain the length of a flagpole's shadow, then the shadow also explains the length of the pole [Psillos] |
Full Idea: If we use geometry and optics to explain the length of shadow cast by a flag-pole, this seems to be reversible, so that the shadow will explain the length of the pole. | |
From: Stathis Psillos (Causation and Explanation [2002], §8.5) | |
A reaction: A neat example which presumably implies that an explanation must involve temporal statements. The laws of physics are totally reversible in time, and so will not suffice to explain events on their own. Time's arrow becomes an axiom of explanation? |
4395 | There are non-causal explanations, most typically mathematical explanations [Psillos] |
Full Idea: There are non-causal explanations, most typically mathematical explanations. | |
From: Stathis Psillos (Causation and Explanation [2002], Intro) | |
A reaction: A crucial basic point, which must be drummed into the minds of ruthless Quinean naturalists, who want to explain everything by quarks and electrons |
4806 | An explanation can just be a 'causal story', without laws, as when I knock over some ink [Psillos] |
Full Idea: Knocking over an ink bottle explains the stain on the carpet, and it is not in doubt because you cannot quote the laws involved; a 'causal story' can give a complete explanation without a law. | |
From: Stathis Psillos (Causation and Explanation [2002], §8.6) | |
A reaction: But why is he so clumsy, and the bottle so unstable? Was it really (Freudian) an 'accident'? There is no end to complete explanation. But 'I was clumsy this once' and 'I am always clumsy' are equally good explanations. |
4404 | Maybe explanation is entirely relative to the interests and presuppositions of the questioner [Psillos] |
Full Idea: Some philosophers focus on the so-called 'pragmatics of explanation' - that an explanation is an answer to a 'why' question, and the relevant answer will depend on the presuppositions or interests of the questioner. | |
From: Stathis Psillos (Causation and Explanation [2002], Intro) | |
A reaction: This seems to me right. Explanation is an entirely human business, not a feature of nature, and most explanations will track back to the big bang if you have the patience, but they always terminate because of pragmatic considerations. But fobbing off? |
4803 | An explanation is the removal of the surprise caused by the event [Psillos] |
Full Idea: An explanation amounts to the removal of the initial surprise that accompanied the occurrence of the event. | |
From: Stathis Psillos (Causation and Explanation [2002], §8.2) | |
A reaction: This is a nice simple point. It makes explanation relative. God requires no explanations, small children require many. The implication is that explanations make events predictable, which means they must either offer inductive generalisations, or laws. |
