10. Modality / C. Sources of Modality / 5. Modality from Actuality
12468 A state of affairs is only possible if there has been an actual substance to initiate it [Pruss]
     Full Idea: Non-actual states of affairs are possible if there actually was a substance capable of initiating a causal chain, perhaps non-deterministic, that could lead to the state of affairs that we claim is possible.
     From: Alexander R. Pruss (The Actual and the Possible [2002]), quoted by Jonathan D. Jacobs - A Powers Theory of Modality §4.2
     A reaction: This is roughly my view. There are far fewer possibilities in heaven and earth than are dreamt of in your philosophy, Horatio. Logical possibilities and fantasy possibilities are not real possibilities.
16. Persons / C. Self-Awareness / 3. Limits of Introspection
3102 Why don't we experience or remember going to sleep at night? [Magee]
     Full Idea: As a child it was incomprehensible to me that I did not experience going to sleep, and never remembered it. When my sister said 'Nobody remembers that', I just thought 'How does she know?'
     From: Bryan Magee (Confessions of a Philosopher [1997], Ch.I)
     A reaction: This is actually evidence for something - that we do not have some sort of personal identity which is separate from consciousness, so that "I am conscious" would literally mean that an item has a property, which it can lose.
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / b. Fields
18202 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.
     From: 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'.
