| 8560 | If causal laws describe causal potentialities, the same laws govern properties in all possible worlds [Shoemaker] |
| Full Idea: To the extent that causal laws can be viewed as propositions describing the causal potentialities of properties, it is impossible that the same properties should be governed by different causal laws in different possible worlds. | |
| From: Sydney Shoemaker (Causality and Properties [1980], §08) | |
| A reaction: [He has just asserted that causal potentialities are essential to properties] This is the dramatic basic claim of scientific essentialism, which grows out of Shoemaker's causal account of properties. Note that the laws are just descriptions. |
| 15763 | If properties are causal, then causal necessity is a species of logical necessity [Shoemaker] |
| Full Idea: My theory of properties as causal appears to have the consequence that causal laws are logically necessary, and that causal necessity is just a species of logical necessity. | |
| From: Sydney Shoemaker (Causality and Properties [1980], §09) | |
| A reaction: Where he writes 'logical' necessity I would claim that he really means 'metaphysical' necessity. The point, I take it, is that given the existence of those properties, certain causal efforts must always follow from them. I agree. |
| 8561 | If a world has different causal laws, it must have different properties [Shoemaker] |
| Full Idea: If there are worlds in which the causal laws are different from those that prevail in this world, ..then the properties will have to be different as well. | |
| From: Sydney Shoemaker (Causality and Properties [1980], §09) | |
| A reaction: The next question is whether the same stuff (e.g. gold or water) could have different properties, and I take the the scientific essentialism answer to be 'no'. So the actual stuff (substances?) would have to be different. |
| 8553 | It looks as if the immutability of the powers of a property imply essentiality [Shoemaker] |
| Full Idea: There is a prima facie case for saying that the immutability of the causal potentialities of a property implies their essentiality. ...If they cannot vary across time, they also cannot vary across possible worlds. | |
| From: Sydney Shoemaker (Causality and Properties [1980], §05) | |
| A reaction: This is only the beginning of scientific essentialism, but one of the targets is to save the phenomena. It is also involves unimaginability (of different powers from a given property) implying necessity. |
