Translation Invariance and Miller's Weather Example

    In his 1974 paper \Popper's Qualitative Theory of Verisimilitude" published in the British Journal for the Philosophy of Science David Miller gave his so called `Weather Example' to argue that the Hamming distance between constituents is awed as a measure of proximity to truth since the former is not, unlike the latter, translation invariant. In this present paper we generalise David Miller's Weather Example in both the unary and polyadic cases, characterising precisely which permutations of constituents/atoms can be effected by translations. In turn this suggests a meta-principle of the rational assignment of subjective probabilities, that rational principles should be preserved under translations, which we formalise and give a particular characterisation of in the context of Unary Pure Inductive Logic.
