Two months later James said in a letter to Mrs. Gibbens: "It is singular how I'm learning every day now how the thought of his comment on my experiences has hitherto formed an integral part of my daily consciousness, without my having realized it at all. I interrupt myself incessantly now in the old habit of imagining what he will say when I tell him this or that thing I have seen or heard." * * * * * James remained in London until mid-February of 1883, and took advantage of the opportunity to see more of certain men there--among them Shadworth Hodgson, Edmund Gurney, Croom Robertson, Frederick Pollock, Leslie Stephen, Carveth Reid, and Francis Galton. His eyes were troubling him again, but he did some writing on psychology. After paying another short visit to Paris, he sailed for home in March. IX 1883-1890 _Writing the "Principles of Psychology"--Psychical Research--The Place at Chocorua--The Irving Street House--The Paris Psychological Congress of 1889_ JAMES had now found his feet, professionally, as well as in other ways. He strode ahead on the next stage of his journey with a firmness of which he would have been incapable in the seventies, and carried a heavy burden of work forward, with never a long halt and without ever setting it down, until he had finished the two large volumes of the "Principles of Psychology" in 1890. The previous decade had counted steadily for inward clarification, for health and for confidence. He was no longer harassed by serious illnesses and pursued by the spectre of possible invalidism. Marriage, parenthood--these immense events in a man's spiritual journey--had happened for him within the last four years and had brought him new loves and ambitions. He was no longer perplexed by misgivings about his aims and abilities, but had arrived at the conception of his treatise on psychology and had begun to formulate its chapters. He had become a very successful teacher, and might fairly have suspected himself of being an inspiring one. His work was beginning to be well known outside the halls of his own University.
