James had an immense variety of interests outside philosophy, though perhaps it is unphilosophical to imply that anything can lie outside the range of a true philosopher's vision. His letters are written to many different kinds of persons; the best of them, naturally, are to philosophers and men of letters, who evoked from him an amazing multiplicity of ideas and to whom he let fly a delicious compound of sound reason and jocularity. In characterizing other men he characterized himself. For example, what he says about Royce embraces both men perfectly: "that unique mixture of erudition, originality, profundity and vastness, and human wit and leisureliness." He was fortunate in his human and intellectual contacts. An early and abidingly fortunate contact was that with his father, who was also a "filosofer." His last letter to his father is beautiful. It brings tears, of which the most stoical philosopher need not be ashamed; indeed, one might rather be ashamed if the tears did not come. No one outside the family and a few friends has a right to read that letter, but print has extended the privilege. If Mr. E. V. Lucas or any other anthologist makes a new collection of examples of "the gentlest art," the letter from James to his father should be included. In it two men are portrayed, father and son, both magnificently; if either man had been less than great the letter could not have been written. James was born a philosopher; philosophy was in the blood and in the very air of the household. There is no better instance of the heredity of genius and of predestination to a career. Yet James did not find himself immediately; he floundered about in the world of thought long after the age at which most men have hung out shingles. He was thirty when he was appointed instructor in physiology at Harvard, and his tardiness in establishing himself as a bread-winning citizen fretted him. Lesser men who feel that the expression of their talents has been thwarted or postponed may take comfort from the fact that James's first printed book, the "Psychology," appeared in 1890, when he was forty-eight years old.
