15710 | Bohr explained the periodic table and chemical properties of elements, using the quantum atom [Kumar] |
Full Idea: Bohr used the quantum atom to explain the periodic table and the chemical properties of the elements. ...It was his new theory about the arrangement of electrons inside atoms that explained the placing and grouping of elements in the periodic table. | |
From: Manjit Kumar (Quantum: Einstein and Bohr [2008], Ch 04) | |
A reaction: (second sentence p.133) This is Exhibit A for the idea that essences are explanatory, and are discovered by scientists. The moot point would be whether it is appropriate to describe electron shells as part of the 'essence' of an atom. |
19399 | Prime matter is nothing when it is at rest [Leibniz] |
Full Idea: Primary matter is nothing if considered at rest. | |
From: Gottfried Leibniz (Aristotle and Descartes on Matter [1671], p.90) | |
A reaction: This goes with Leibniz's Idea 13393, that activity is the hallmark of existence. No one seems to have been able to make good sense of prime matter, and it plays little role in Aristotle's writings. |
6011 | There is a remote first god (the Good), and a second god who organises the material world [Numenius, by O'Meara] |
Full Idea: Numenius argues that material reality depends on intelligible being, which depends on a first god - the Good - which is difficult to grasp, but which inspires a second god to imitate it, turning to matter and organizing it as the world. | |
From: report of Numenius (fragments/reports [c.160]) by Dominic J. O'Meara - Numenius | |
A reaction: The interaction problem comes either between the two gods, or between the second god and the world. The argument may have failed to catch on for long when people scented an infinite regress lurking in the middle of it. |
