No class of works is received with more suspicion than those which deal with Science and Religion. Science is tired of reconciliations between two things which never should have been contrasted; Religion is offended by the patronage of an ally which it professes not to need; and the critics have rightly discovered that, in most cases where Science is either pitted against Religion or fused with it, there is some fatal misconception to begin with as to the scope and province of either. But although no initial protest, probably, will save this work from the unhappy reputation of its class, the thoughtful mind will perceive that the fact of its subject-matter being Lawa property peculiar neither to Science nor to Religionat once places it on a somewhat different footing.
