Diversity and change seem to be the central experiences of Western peoples at this point in the twentieth century. Students, now more than ever, need to be given a sense of hope and of the perfectability of humankind. This commentary provides impressionistic description of issues and experiences in the teaching of interdisciplinary humanities courses at both secondary and college levels. A hypothetical course entitled "Man's Futures: The Possibility of Perfectability; or, An Exploration of Change and Choice" is described. This course, adaptable to various grade levels, would involve teachers from many subject fields and would provide students with the motivation to learn the basics in math, science, English, and Latin.
