M. Andrew Holowchak, Ph.D. is a professor of philosophy and history, and editor of 'The Journal of Thomas Jefferson's Life and Times.' He is author/editor of over 65 books and over 270 published essays on topics such as ethics, ancient philosophy, science, psychoanalysis, and critical thinking. His current research is on Thomas Jefferson—he is acknowledged by many scholars to be the world’s foremost authority on the thinking of Jefferson—and has published 27 books and over 200 essays on Jefferson. Like Jefferson, he has a passion for “putting up and pulling down,” but his putting up and pulling down is not architectural, but done on a landscape or in a garden. He also enjoys lifting weights, bike riding, conferencing, and talking about Thomas Jefferson.
