  This paper is an answer to the first part of Adrian Kent's One World versus
Many : the Inadequacy of Everettian Accounts of Evolution, Probability, and
Scientific Confirmation [arXiv:0905.0624]. We take issue with Kent's arguments
against many-world interpretations of quantum mechanics. We argue that his
reasons for preferring single-world interpretations are logically flawed and
that his proposed singleworld alternative to probability theory suffers from
conceptual problems. We use a few thought-experiments which show that the
problems he raises for probabilities in multiverses also apply in a single
universe.
