| 14913 | We explain by deriving the properties of a phenomenon by embedding it in a large abstract theory [Ladyman/Ross] |
| Full Idea: Theoretical explanation is the derivation of the properties of a relatively concrete and observable phenomenon by means of an embedding into some larger, relatively abstract and unobservable theoretical structure. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 2.1.1) | |
| A reaction: [they are citing Michael Friedman 1981 p.1] This sounds like covering law explanation, but the theoretical structure will be a set of intersecting laws, rather than a single law. How do you explain the theoretical structure? |
| 13092 | The essence of substance is the law of its changes, as in the series of numbers [Leibniz] |
| Full Idea: The essence of substance consists in ...the law of the sequence of changes, as in the nature of the series in numbers. | |
| From: Gottfried Leibniz (works [1690], A 6.3.326), quoted by Cover,J/O'Leary-Hawthorne,J - Substance and Individuation in Leibniz 6.1.2 | |
| A reaction: Thus we might say, in this spirit, that the essence of number is the successor operation, as defined by Dedekind and Peano (and perhaps their amenability to inductive proof). I like this. Metaphysicians rule - they penetrate the heart of nature. |
