Photography seemed to be something quite different, at the beginning; it seemed to prove that there was only one world, not many-one visible world, anyway.
First, while an assignment fixes a corresponding specification, the set of sentences true on that assignment, the reverse does not hold: there is no such thing as the assignment corresponding to a given specification; assignments (roughly, "models") and specifications ("theories") are related many-one.
The many-many relationship will be divided into two separable components: the one-many relation of "compositional plasticity" or "multiple realization" whereby a given higher-level property can be realized by any number of distinct lower-level state types (Putnam, 1960, 1967; Fodor, 1974; Boyd, 1980); and the converse many-one relation of "context sensitivity" or "multiple realization complement" whereby a given lower-level property can serve to realize any number of distinct higher-level state types (Richardson, 1979, pp.

Whilst the reasons for this increase are not entirely clear-and no doubt there are many-one is certainly poor practice due to insufficient technical expertise or because technical advice is not followed.
