| 4958 | Identities like 'heat is molecule motion' are necessary (in the highest degree), not contingent [Kripke] |
| Full Idea: I hold that characteristic theoretical identifications like 'heat is the motion of molecules', are not contingent truths but necessary truths, and I don't just mean physically necessary, but necessary in the highest degree. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 2) | |
| A reaction: This helps to keep epistemology and ontology separate. The contingency was in the epistemology. That the identity is 'physically necessary' seems obvious; that it is necessary 'in the highest degrees' implies an essentialist view of nature. |
| 17472 | Thick mechanisms map whole reactions, and thin mechanism chart the steps [Weisberg/Needham/Hendry] |
| Full Idea: In chemistry the 'thick' notion of a mechanism traces out positions of electrons and atomic cores, and correlates them with energies, showing the whole reaction. 'Thin' mechanisms focus on a discrete set of intermediate steps. | |
| From: Weisberg/Needham/Hendry (Philosophy of Chemistry [2011], 5.1) |
| 17471 | Using mechanisms as explanatory schemes began in chemistry [Weisberg/Needham/Hendry] |
| Full Idea: The production of mechanisms as explanatory schemes finds its original home in chemistry. | |
| From: Weisberg/Needham/Hendry (Philosophy of Chemistry [2011], 5.1) | |
| A reaction: This is as opposed to mechanisms in biology or neuroscience, which come later. |
