6156 | The 17th century reintroduced atoms as mathematical modes of Euclidean space [Rowlands] |
Full Idea: The seventeenth century revolution reintroduced the classical concept of the atom in somewhat new attire as an essentially mathematical entity whose primary qualities could be precisely quantified as modes or aspects of Euclidean space. | |
From: Mark Rowlands (Externalism [2003], Ch.2) | |
A reaction: Obviously this very abstract view of atoms didn't last, once they began to identify specific physical atoms, such as oxygen. This view fits in with Newton's use of pure (abstract) points such as the 'centre of gravity'. |
6170 | Natural kinds are defined by their real essence, as in gold having atomic number 79 [Rowlands] |
Full Idea: Part of what it means to be a natural kind is that they are defined by a real essence, a constitution that marks them out as the substance they are (as water is essentially H2O, and gold essentially has atomic number 79). | |
From: Mark Rowlands (Externalism [2003], Ch.6) | |
A reaction: A 'real essence' would be the opposite of a 'conventional essence', which is just a human way of seeing things. |
3962 | Cause and effect relations between events must follow strict laws [Davidson] |
Full Idea: If two events are related as cause and effect, there is a strict law under which they may be subsumed. | |
From: Donald Davidson (Davidson on himself [1994], p.231) | |
A reaction: Davidson admits that this is open to challenge (though Hume and Kant supported it). It does seem to be central to our understanding of nature. |
17993 | Laws are relations of kinds, quantities and qualities, supervening on the essences of a domain [Vetter] |
Full Idea: The laws of a domain are the fundamental, general explanatory relationships between kinds, quantities, and qualities of that domain, that supervene upon the essential natures of those things. | |
From: Barbara Vetter (Dispositional Essentialism and the Laws of Nature [2012], 9.3) | |
A reaction: Hm. How small can the domain be? Can it embrace the multiverse? Supervenience is a rather weak relationship. How about 'are necessitated/entailed by'? Are the relationships supposed to do the explaining? I would have thought the natures did that. |
