Not only in the 16th century, but certain philosophers of a later date have questioned the idiot's place in creation, and have disputed his right to be classed among the human family; and some scientists--believers in the so-called doctrine of Evolution, as applied to the Descent of Man--have gone so far as to pretend that the brain of the microcephalic idiot is so far removed from the human type, as to constitute him a connecting link between man and the anthropoid apes! Now, the interesting results of our training institutions, showing _the capacity for progressive improvement_ which exists in the idiot, gives the lie to this absurd and purely sensational hypothesis. Here let me add that I strongly deprecate introducing the _odium theologicum_ into the discussion of this subject, being fully conscious of the futility of attempting to check an unwelcome or distasteful theory by means of ecclesiastical censures; and I further admit that in anything like a scientific demonstration of truth, an appeal to the affections would be absurdly out of place.[36] Moreover, I should not reject the Darwinian theory from any sensational notion that its adoption was derogatory to Man's dignity, and I fully echo the sentiment of the naturalist who said that he would prefer being descended from a good honest monkey, than to be obliged to avow himself the offspring of certain fanatical enemies of scientific knowledge and progress; but I do complain of the tendency of the present day to accept new ideas without knowing or caring how to sift them. Everything is hypothetical, and allowed to enter the mind through the ivory gate of fancy; and on purely hypothetical premises, an attempt is made to found conclusive arguments. Strip the assertions of all their vagueness and superficial varnish, and reduce them to a skeleton of logical statement, and we shall see how much is assumed and how little is proved; and we shall find that we are asked to accept a chain of hypotheses, as if it were an induction founded on ascertained and indisputable facts. In thus expressing myself, I wish to add that the ultimate goal of the scientist is the establishment of truth, and I should as soon attempt to stop the progress of the avalanche that has become dislodged from the mountain top, as to try to bar the path of scientific progress, or to extinguish the torch of discovery. The tide of scientific truth will continue to flow on in spite of the modern Canutes, who may utter from time to time their imperial commands to stay its course. _Magna est veritas et prevalebit._
