interest in law, which are always easily traced among the sciences, even the sciences in the opposite camps of matter and mind, of any particular time. Atomism in physics is contemporary with atomism in psychology and with individualism in political philosophy; a monarchical politics with an anthropomorphic, creationalistic theology and an also monarchical physically centred astronomy, whether heliocentric or geocentric; and a Newtonian astronomy, which really makes a law or force instead of an individual body the centre and control of the solar system, with democracy or constitutionalism, and with inductive instead of deductive logic and naturalistic instead of dogmatic theology; so that at no time, whatever the scientist's special interest, whatever his [p.098] special syllable, can he fail to have at least a formal sympathy with others. Such analogies among the sciences, so often recognized and so absorbingly interesting to the students of the history of thought, if not exactly doors in the panelling, may be said to make the panelled partitions at least translucent if not unsubstantial and transparent. But the most important fact in illustration of our case against specialism is yet to be considered, and unfortunately it takes us where to some the waters may seem dangerously deep. Not only for reasons already given and emphasized is the special science a misnomer, a contradiction in terms, except in so far as specialism be taken merely as an incident, not without its humour, of scientific method, but also for the same reasons (and chiefly because the truth and reality of the universe are bound to be conserved) every special science must sooner or later develop its doctrines either into direct paradoxes or into tenets that oppose and contradict each other. Thus, as has been shown, specialism in science is itself a paradox, and, as now asserted, every special science assuming precise form and real validity becomes a home of paradoxical or contradictory doctrines. Indeed, these doctrines just through their opposition appear be the most effective agents of that compensation for neglected points of view, or conservation of all points of view, which we are insisting is for ever forced upon the scientific specialist. In the cases of physical epistemology and epistemological physics we have already seen doctrines working to this end. In those cases the real treachery to the avowed [p.099] standpoints lay in virtual when not open contradiction. And, for the general principles, is it not quite clear that nothing so surely as contradiction in any given point of view, or in the specific doctrines developed under it, can serve the interests of any other points of view? I have heard it said, but by whom originally I do not know, that a paradox or contradiction was only the mind on tiptoe struggling to look over a very high wall.
