The concept of a field gradually replaced the substances in explaining relations between charges [Einstein/Infeld]
|
|
Full Idea:
In the beginning the field concept was no more than a means of facilitating the understanding of phenomena. ...In the new field language it is the field and not the charges themselves which is essential. The substance was overshadowed by the field.

Einstein,A/Infeld,L (The Evolution of Physics [1938], p.151), quoted by Penelope Maddy - Naturalism in Mathematics II.4

A reaction:
This is very important for philosophical metaphysicians, especially those like me who want to explain the universe by the nature of the stuff that composes it. The 'stuff' had better not be simplistic individual 'substances'.

God's existence is either necessary or impossible, and no one has shown that the concept of God is contradictory [Malcolm]
|
|
Full Idea:
God's existence is either impossible or necessary. It can be the former only if the concept of such a being is self-contradictory or in some way logically absurd. Assuming that this is not so, it follows that He necessarily exists.

|
From:
Norman Malcolm (Anselm's Argument [1959], §2)
|
|
A reaction:
The concept of God suggests paradoxes of omniscience, omnipotence and free will, so self-contradiction seems possible. How should we respond if the argument suggests God is necessary, but evidence suggests God is highly unlikely?
