The confusion between the large and complex nervous organisation and a diseased or defective condition has been aided by the fact that the genius--the truly nervous man in the higher sense, the largest offshoot from the great force-current--is invariably placed in hard conditions in youth. He pays the penalty for being before his time. He belongs to a higher standard than that into which he is forced. In the family nest he is the ugly duckling; in the world he is persecuted. When his marvellous insight and keen intelligence enable him to foresee the remote but lasting pernicious effects of practices that are clung to by his fellows for the sake of their immediate advantage, he falls by the hand of the assassin or is universally credited with madness. Centuries after his death, when his community has painfully toiled to his level, his greatness is recognised, and he is deified or canonised. It is perhaps well that the growth of such offshoots is limited in every age by a mental atmosphere as real as the atmosphere surrounding our globe and limiting our aerial flights. Apparently it is not decreed that human progress shall be rapid. Nevertheless, a too wholesale destruction of our most highly organised members must certainly ensure that evolution backwards of which I spoke in another chapter. The fact is, we find it hard to distinguish between genius and eccentricity. The uncontrolled eccentricities of the matured do so much harm, that it is found necessary to suppress them. But we should remember that the genius is always eccentric in youth unless he is allowed a very wide area for development--and this is the last service his friends are willing to do him. He has, as it were, to develop into a large circle. His great vitality and many-sidedness enable him to take advantage of any chance diminution of pressure, and in each direction where resistance is least he shoots out long points and angles. If any of these angles be lopped or violently discouraged, he may be a one-sided or distorted being. Let him alone, however, and in due course he will fill in the spaces between his angles and grow into a finely rounded being. But the magnificent virtue of letting one another alone is still little cultivated by our community. Now, persons who are merely eccentric do not shoot out their angles in a variety of directions and fill in the spaces as soon as opportunity is granted them. They have only one or two long angles, to which they continue to add till they become such a nuisance that the peace and safety of the community demand their control. Both genius and eccentricity being hereditary, and the logical outcome of extreme eccentricity in one generation being insanity in the next, we need to exercise care in our dealings with these abnormal developments. To drive men of genius into the ranks of the eccentrics is a very dangerous policy. Let us honestly recognise the fact that we are all of us potential madmen.
