William Thomson's image as a professional mathematical physicist who adheres, particularly in his work in classical thermodynamics, to a strict experimental basis for his science, avoids speculative hypotheses, and becomes renowned for his omission of philosophical declarations has been reinforced in varying degrees by those historians who have attempted, as either admirers or critics of Thomson, to describe and assess his life. J. G. Crowther, for example, sees him as a thinker of great intellectual strength, but deficient in intellectual taste; (...) a scientist aware only of his immediate work and without depth of vision. Not well read in the literature of the subjects of his research, Thomson is seen, moreover, as one whose achievements owe little to the work of others, and whose great personality ‘is an expression in the realm of ideas of the power and blindness of capitalism’, especially through ‘his view of the world in terms of engineering conceptions’. On the other hand, even Sir Joseph Larmor, for whom Thomson was nothing less than a hero, is to be found ascribing to him the epithet of pragmatist. (shrink)
