7021 | If the world is theory-dependent, the theories themselves can't be theory-dependent [Heil] |
Full Idea: If the world is somehow theory-dependent, this implies, on pain of a regress, that theories are not theory-dependent. | |
From: John Heil (From an Ontological Point of View [2003], 06.4) | |
A reaction: I am not sure where this puts the ontology of theories, but this is a nice question, of a type which never seems to occur to your more simple-minded relativist. |
7026 | Science is sometimes said to classify powers, neglecting qualities [Heil] |
Full Idea: The sciences are sometimes said to be in the business of identifying and classifying powers; the mass of an electron, its spin and charge, could be regarded as powers possessed by the electron; science is silent on an electron's qualities. | |
From: John Heil (From an Ontological Point of View [2003], 11.2) | |
A reaction: Heil raises the possibility that qualities are real, despite the silence of science; he wants colour to be a real quality. I like the simpler version of science. Qualities are the mental effects of powers; there exist substances, powers and effects. |
6027 | From the fact that some men die, we cannot infer that they all do [Philodemus] |
Full Idea: There is no necessary inference, from the fact that men familiar to us die when pierced through the heart, that all men do. | |
From: Philodemus (On Signs (damaged) [c.50 BCE], 1.3) | |
A reaction: This is scepticism about the logic of induction, long before David Hume. This is said to be a Stoic argument against Epicureans - though on the whole Stoics are not keen on scepticism. |
7060 | One form of explanation is by decomposition [Heil] |
Full Idea: One form of explanation is by decomposition. | |
From: John Heil (From an Ontological Point of View [2003], 19.8) | |
A reaction: This is a fancy word for taking it apart, presumably to see how it works, which implies a functional explanation, rather than to see what it is made of, which seeks an ontological explanation. Simply 'decomposing' something wouldn't in itself explain. |
