Among these "eccentrics" a few have been reckoned geniuses by their contemporaries or by posterity. In such cases society hesitates to apply its usual formulæ. One cannot condemn out of hand a Shelley. He is not of the run of men.
Shelley was one of those spokesmen of the _a priori_, one of those nurslings of the womb, like a bee or a butterfly, a dogmatic, inspired, perfect, and incorrigible creature.... Being a finished child of nature, not a joint product, like most of us, of nature, history, and society, he abounded miraculously in his own clear sense, but was obtuse to the droll miscellaneous lessons of fortune. The cannonade of hard inexplicable facts that knocks into most of us what little wisdom we have, left Shelley dazed and sore, perhaps, but uninstructed.[1]

It is difficult to draw the line in some cases between genius and insanity.[1] There have been time and again in society Cassandras who have spoken true prophecies and have been thought mad. There have been, on the other hand, those who, having some of the external eccentricities of genius, have given an illusive impression of greatness. The professional Bohemian likes to make himself great by wearing his hair long and living in a garret. But it is unquestionably true that a highly sensitive and creative mind is often ill at ease in the world of action, and remains a vagabond, an _enfant terrible_ or an eccentric all through life. It remains a fact that in contemporary society there are a small number of people, some of them of considerable talents, who simply cannot be made to fit into the social routine. For such Bertrand Russell suggests a "vagabond's wage." This he conceives as being just large enough to enable them to get along, to give them a chance to wander and experiment, but sufficiently small to penalize them for not settling down to the accustomed social routines.[2]
