4793 | "All gold cubes are smaller than one cubic mile" is a true universal generalisation, but not a law [Psillos] |
Full Idea: The statement "all gold cubes are smaller than one cubic mile" seems to have all the features demanded of a lawlike statement, yet it can hardly be said to express a law. It is a merely true universal generalisation. | |
From: Stathis Psillos (Causation and Explanation [2002], §5.3) | |
A reaction: Nice example. A trickier case is "all cubes of uranium are smaller than one cubic mile", which sounds like part of a law. It suggests a blurred borderline between the two. How much gold is there in the universe? Is that fact a natural necessity? |
4397 | Regularity doesn't seem sufficient for causation [Psillos] |
Full Idea: A rather important objection to Humeanism has been that regularity is not sufficient for causation. | |
From: Stathis Psillos (Causation and Explanation [2002], Intro) | |
A reaction: Obviously a crucial problem, but the Humean view can defend itself by introducing other constant conjunctions. We don't observe events in isolation, but as part of a pattern of regularities. |
4401 | It is not a law of nature that all the coins in my pocket are euros, though it is a regularity [Psillos] |
Full Idea: It is not a law of nature that all the coins in my pocket are euros, though it is a regularity. | |
From: Stathis Psillos (Causation and Explanation [2002], Intro) | |
A reaction: Good example, but it doesn't demolish the regularity view. We should come to conscious minds last. There aren't many other unfailing regularities that are not laws. |
4792 | A Humean view of causation says it is regularities, and causal facts supervene on non-causal facts [Psillos] |
Full Idea: The Humean view depends on the conjunction of two general theses: first, causation is tied to regularity; secondly, causal facts supervene on non-causal facts. | |
From: Stathis Psillos (Causation and Explanation [2002], §4.5.4) | |
A reaction: If causation is just regularities, this means it is patterns observed by us, which means causation doesn't actually exist. So Hume is wrong. Singular causation is possible, and needs explanation. |
4801 | The regularity of a cock's crow is used to predict dawn, even though it doesn't cause it [Psillos] |
Full Idea: A regularity can be used to predict a future event irrespective of whether it is deemed causal or not. A farmer can predict that dawn has broken on hearing the cock's crow. | |
From: Stathis Psillos (Causation and Explanation [2002], §8.1) | |
A reaction: This seems a highly significant criticism of any view that says regularity leads to causation, which is the basis of induction, which leads to counterfactual claims, and thus arrives a the laws of nature. |
4796 | Laws are sets of regularities within a simple and strong coherent system of wider regularities [Psillos] |
Full Idea: In the 'web-of-laws' approach, laws are those regularities that are members of a coherent system of regularities, in particular, a system that can be represented as a deductive axiomatic system, striking a good balance between simplicity and strength. | |
From: Stathis Psillos (Causation and Explanation [2002], §5.6) | |
A reaction: Psillos attribute this view to Mill, Ramsey and Lewis. It is the obvious candidate for a fully developed Humean empiricist system, where regularities reinforce one another. I think laws are found in mechanisms, not in regularities, which are symptoms. |
4799 | Dispositional essentialism can't explain its key distinction between essential and non-essential properties [Psillos] |
Full Idea: Many philosophers will find dispositional essentialism unappealing, not least because it seems to fail to explain how (and in virtue of what) there is this supposed fundamental distinction between essential and non-essential properties. | |
From: Stathis Psillos (Causation and Explanation [2002]) | |
A reaction: Maybe there is no precise definition, but any idiot can see that some properties of gold are essential (mass) and others non-essential (attractive to jackdaws). It's a fair question, but is this the strongest objection to essentialism? |
4780 | In some counterfactuals, the counterfactual event happens later than its consequent [Psillos] |
Full Idea: In "had the acrobat jumped, there would have been a safety net" the antecedent of the counterfactual (the jumping) is temporally later than the consequent (the installation of the net). | |
From: Stathis Psillos (Causation and Explanation [2002], §3.3) | |
A reaction: This blocks anyone (e.g. David Lewis) who tries to define counterfactual claims entirely in terms of a condition followed by a consequence. Nice example. |
4791 | Counterfactual theories say causes make a difference - if c hadn't occurred, then e wouldn't occur [Psillos] |
Full Idea: The counterfactual theory is a non-Humean relation between singular events; the thought is that causation makes a difference - to say that c causes e is to say that if c hadn't occurred, e wouldn't have occurred either. | |
From: Stathis Psillos (Causation and Explanation [2002], §4.5.4) | |
A reaction: Helpful. I'm beginning to think that this theory is wrong. It gives an account of how we see causation, and a test for it, but it says nothing about what causation actually is. |
