This paper presents an argument for the claim that historical events are unique in a nontrivial sense which entails the inapplicability of the Hempelian D-N model to historical explanations. Some previous criticisms of Hempel are shown to be general criticisms of the D-N model which can be outflanked in cases where a reduction to fundamental laws is available. I then survey grounds for denying that explanations by reasons can be effectively reduced to causal explanations, and for rejecting methodological individualism. I (...) conclude with some positive remarks concerning the structure of historical explanations and sense in which historical events are unique. (shrink)

The multiverse hypothesis is the leading alternative to the competing fine-tuning hypothesis. The multiverse dispels many aspects of the fine-tuning argument by suggesting that there are different initial conditions in each universe, varying constants of physics, and the laws of nature lose their known arbitrary values; thus, making the previous single-universe argument from fine- tuning incredibly weak. The position that will be advocated will be that a form of multiverse could exist and that any level of Tegmark's multiverse does not (...) circumvent the fine-tuning argument for the existence of a fine-tuner. An argument will be presented suggesting that the multiverse could strengthen the fine-tuning argument by narrowing down the parameters of the data to a more fundamental description needed for the multiverse to function as it does since it may be the case that some physical descriptions are not the same in every universe. That is, the task of explaining how the multiverse mechanism functions cannot be accounted for by the multiverse itself. Fine-tuning by a mind serves as a sufficient and best explanation for the data. (shrink)
