In 1919, friends of Professor George Holmes Howison, many of whom had also been his students, established the Howison Lectures in Philosophy at the University of California. In their bequest, the donors wrote, "Professor Howison held the reasoned conviction that this world to its very depth is kindred to the human spirit; that it is a community of free persons, finite and infinite, sustained by the vision of the Perfect; and all his great powers were directed to awaken in others a loyalty to these ideas. And those, it would seem, would most speak from a foundation in his memory who were able to share with him this high purpose and conviction."
