Difficulties over probability have often been considered fatal to the Everett interpretation of quantum mechanics. Here I argue that the Everettian can have everything she needs from â€˜probabilityâ€™â€¦ (More)

According to Bayesian epistemology, the epistemically rational agent updates her beliefs by conditionalization: that is, her posterior subjective probability after taking account of evidence X, Pnew,â€¦ (More)

I explore the prospects for modelling epistemic rationality (in the probabilist setting) via an epistemic decision theory, in a consequentialist spirit. Previous work has focused on cases in whichâ€¦ (More)

Harsanyi claimed that his Aggregation and Impartial Observer Theorems provide a justification for utilitarianism. This claim has been strongly resisted, notably by Sen and Weymark; the latter argueâ€¦ (More)

The Everett (many-worlds) interpretation of quantum mechanics faces a prima facie problem concerning quantum probabilities. Research in this area has been fast-paced over the last few years,â€¦ (More)

Recent work in the Everett interpretation has suggested that the problem of probability can be solved by understanding probability in terms of rationality. However, there are two problems relating toâ€¦ (More)

Bacteria and actinomycetes are probably the most common wood-inhabiting microorganisms, certainly they are the most adaptable in terms of environmental influences. When considering them as factors inâ€¦ (More)

Much of the evidence for quantum mechanics is statistical in nature. The Everett interpretation, if it is to be a candidate for serious consideration, must be capable of doing justice to reasoning onâ€¦ (More)

The CPT theorem of quantum field theory states that any relativistic (Lorentz-invariant) quantum field theory must also be invariant under CPT, the composition of charge conjugation, parity reversalâ€¦ (More)

The following argument is adapted from that in Bell (1955). I cannot quite follow Bellâ€™s argument1, so I have changed it to generate a result I understand. In outline, the result is as follows. Weâ€¦ (More)
