Abstract
William James declared a moral war, Charles Peirce a metaphysical one: "fall into the ranks then" was his battle cry,
follow your colonel. Keep your one purpose steadily and alone in view, and you may promise yourself the attainment of your sole desire, which is to hasten the chariot wheels of redeeming love. (6.448:1893)
Peirce's was a war not against war, but against the metaphysical equivalent of war, individuation. In the field of social philosophy, Peirce's enemy appeared under the alias of Darwinism, which Peirce fought with Christian Love. In the field of metaphysics, it appeared under the alias of nominalism, which Peirce fought with his special brand of pragmatic realism. But most challenging of all, the enemy appeared within Peirce's own thought under the alias of what I call Kantian conceptualism, and it took Peirce most of his career to win the battle.
