A contingent fact is one that is actual but could have been non-actual, where the relevant notion of possibility is that of broadly metaphysical possibility.
By axiom 2, it follows that if there are any wholly contingent facts, then any fact overlaps C if, and only if, that fact overlaps some wholly contingent fact.
A proposition is a picture of reality, and the reality depicted by meaningful propositions is a realm of contingent facts. The doctrine that "there is no compulsion making one thing happen because another has happened" has, for Wittgenstein, important implications for ethics.(6)

Thus, guided by the heuristic question of contingency, following O'Connor as a kind of philosophical Virgil, we are led from modal logic to metaphysics to natural theology, which is the subject of the second part of the book.
Interpretations, however, are never true--at least in this sense--because they merely express the values of the interpreter, which depend on contingent facts about him, such as his personal history and the attitudes of his community.
It is argued that, ironically, contingent facts about the temporal properties of consciousness are very difficult to square with presentism unless some form of mind--body dualism is embraced.
