Lancaster[14] gathered and glanced over a thousand biographies, from which he selected 200 for careful study, choosing them to show different typical directions of activity. Of these, 120 showed a distinct craze for reading in adolescence; 109 became great lovers of nature; 58 wrote poetry, 58 showed a great and sudden development of energy; 55 showed great eagerness for school; 53 devoted themselves for a season to art and music; 53 became very religious; 51 left home in the teens; 51 showed dominant instincts of leadership; 49 had great longings of many kinds; 46 developed scientific tastes; 41 grew very anxious about the future; 34 developed increased keenness of sensation or at least power of observation; in 32 cases health was better; 31 were passionately altruistic; 23 became idealists; 23 showed powers of invention; 17 were devoted to older friends; 15 would reform society; 7 hated school. These, like many other statistics, have only indicative value, as they are based on numbers that are not large enough and upon returns not always complete. A few typical instances from Lancaster must here suffice. Savonarola was solitary, pondering, meditating, felt profoundly the evils of the world and need of reform, and at twenty-two spent a whole night planning his career.

Tolstoi found the aspect of things suddenly changed. Nature put on a new appearance. He felt he might commit the most dreadful crimes with no purpose save curiosity and the need of action. The future looked gloomy. He became furiously angry without cause; thought he was lost, hated by everybody, was perhaps not the son of his father, etc. At seventeen he was solitary, musing about immortality, human destiny, feeling death at hand, giving up his studies, fancying himself a great man with new truths for humanity. By and by he took up the old virtuous course of life with fresh power, new resolutions, with the feeling that he had lost much time.
