In establishing unexpected cross-connections between physics, the theory of perception, and logic, Hyder also makes a valuable contribution to the history of 19th century science. In particular, the links he establishes between early sensory physiology and the logicism of Russell and Frege yield a sharper and more plausible account of the notion of a "space" of possible meanings than has hitherto been available in the secondary literature. In showing this notion to be a formal precursor to that of a language game, the study also provides important pointers for the interpretation of Wittgenstein's late work.
