Dear friend in philosophy
Thank you for your recent charming company. As you might recall from our discussion at the restaurant, I remarked glibly that omniscience entails fatalism. You, of course, disagreed with me on the grounds that God’s existence is somehow atemporal. Since informal discussions over lunch, sadly cut short by your disappearance, are less than conducive to heavy philosophy, I thought this clarification in order.

I believe I can prove my assertion. Given a few reasonable assumptions, and a particular understanding of the concepts involved, we should be able to (more…)

I shall consider how the truthmaker theories of Rhoda and Cameron fare against the objection – the former because of its unique relevance to the objection; the latter because it is the most sophisticated presentist truthmaker theory.

Presentism is the position that only the present exists. An easy way to understand this is (more…)
