The chief event of the period is the publication of the long-awaited
Principles of Psychology, which produced congratulatory and critical
letters from Oliver Wendell Holmes, Christine Ladd Franklin, Shadworth
Hollway Santayana, James Mark Baldwin, and others. James also devoted
much effort to ensuring that Harvard did not fall behind its many
emerging rivals in psychology, showed strains and a developing sense of
rivalry with Granville Stanley Hall, a former student now established as
president of nearby Clark University, and furthering Mary Whiton
Calkins' efforts to become a graduate student at Harvard. Also
documented in this volume are the appearance of James's major essay in
ethics, "The Moral Philosopher and the Moral Life," the birth of James's
last child and the death of his sister Alice, and the years of his long
European sabbatical.
