A new name for an old idea? A student of Harvey Carr reflects

My chief mentor in graduate school at Chicago was Harvey Carr, who spent most of his professional life at The University of Chicago as professor of experimental psychology. He was admired and loved by his graduate students not only as a masterly teacher and for his accumen in directing research, but also as a man of personal integrity. On the assumption that he is not as well known as he should be by the present generation of psychologists, this essay is presented. The paper reports on the testimonials of his many students on the occasion of his retirement, some reminiscences on the part of the essayist, and an analysis of Carr's systematic position.
