10. Modality / B. Possibility / 8. Conditionals / c. Truth-function conditionals
There are some assertable conditionals one would reject if one learned the antecedent [Jackson, by Edgington]
     Full Idea: Jackson came to realise that there are assertable conditionals which one would not continue to believe if one learned the antecedent, such as Lewis's "If Reagan worked for the KGB, I'll never find out".
     From: report of Frank Jackson (Conditionals [1987]) by Dorothy Edgington - Conditionals (Stanf) 4.2
     A reaction: That pesky David Lewis made trouble for everybody. Edgington agrees that his earlier formulation (Idea 14288) holds good for nearly all cases. There is a self-referential element in Lewis's example.
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / b. Fields
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'.
29. Religion / D. Religious Issues / 3. Problem of Evil / a. Problem of Evil
Is evil an illusion, or a necessary contrast, or uncontrollable, or necessary for human free will? [Mackie, by PG]
     Full Idea: Perhaps evil is an illusion, or it is necessary for good to exist, or in humans it is required because we have free will, or God lacks the full power to control it, but none of these looks convincing.
     From: report of J.L. Mackie (Evil and Omnipotence [1955], §B) by PG - Db (ideas)
The propositions that God is good and omnipotent, and that evil exists, are logically contradictory [Mackie, by PG]
     Full Idea: There is a contradiction between the propositions that God is wholly good, God is omnipotent, and evil exists, and one of them has got to give way (assuming good eliminates evil, and omnipotence has no limit).
     From: report of J.L. Mackie (Evil and Omnipotence [1955], Pref.) by PG - Db (ideas)
