  The particles-and-boxes picture above corresponds to the physicists’ multidimensional ‘phase space’, which describes which individuals have which properties, whereas the field- theoretic representation corresponds to ‘distribution space’, which simply describes which properties are instantiated in what numbers. Huggett has pointed out that the former supports haecceitism, whereas the latter does not and, furthermore, that the empirical evidence provides no basis for choosing between these two spaces (Huggett 1999a). Thus the claim that classical statistical mechanics is wedded to haecceitism also becomes suspect.
