The less gifted portion of the educated public was greatly delighted some years ago by a work by Dr. Nordau called _Degeneration_, in which a great number of abnormal people were studied in a pseudo-scientific manner and shown to be abnormal beyond any possibility of dispute. Mostly the samples selected were men of exceptional artistic and literary power. The book was pretentious and inconsistent--the late Lord Tennyson was quoted, I remember, as a typically “sane” poet in spite of the scope afforded by his melodramatic personal appearance and his morbid passion for seclusion--but it did at least serve to show that if we cannot call a man stupid we may almost invariably call him mad with some show of reason. The public read the book for the sake of its abuse, applied the intended conclusion to every success that awakened its envy, and failed altogether to see how absolutely the definition of madness was destroyed. But if madness is indeed simply genius out of hand and genius only madness under adequate control; if imagination is a snare only to the unreasonable and a disordered mind only an excess of intellectual enterprise--and really none of these things can be positively disproved--then just as reasonable as the idea of suppressing the reproduction of madness, is the idea of breeding it! Let us take all these dull, stagnant, respectable people, one might say, who do nothing but conform to whatever rule is established about them and obstruct whatever change is proposed to them, whose chief quality is a sheer incapacity to imagine anything beyond their petty experiences, and let us tell them plainly, “It is time a lunatic married into your family.” Let no one run away from this with the statement that I propose such a thing should be done, but it is, at any rate in the present state of our knowledge, as reasonable a proposal, to make as its quite frequently reiterated converse.
