Regarding one of Peter’s works Dean Emeritus of the Catholic University of America’s School of Philosophy Jude P. Dougherty has said:

“Given the breadth of his historical survey and his analytic power, he is reminiscent of Hegel at his most sweeping. This is obviously the work of a mature scholar, the reflections of a learned and serious philosopher who shows clearly that ideas have consequences, even when they are of the most removed and metaphysically abstract. . .. To open this book is to be captivated by Redpath's unconventional view of modernity. One puts it down with the conviction that one has encountered a profound thinker at work.”

In 2014, Redpath's book A Not-So-Elementary Christian Metaphysics was listed by Mark Brumley, CEO of Ignatius Press, and James V. Schall, S.J. as among "The Best Books I Read in 2014" for The Catholic World Report:


In 2018, in an article especially devoted to discussing this book [published in The New Oxford Review (May, 2018, entitled "On What is Generated by the Human Intellect: Why are Things the Way They are?")], Fr. Schall writes:

 "A Not-So-Elementary Christian Metaphysics is a rich book, and Redpath has a clear style. He breaks complicated issues into short, intelligible units. He repeats difficult points, and then he repeats them again, rephrasing them to make them understandable. This is a book I wish I’d had in my earlier years of studies. In reading it, I found that many notions and points I had often wondered about, or about which I needed more explanation, were much clearer after Redpath dealt with them. For us metaphysicians, this is a book of refreshment and a review of what we thought we knew."

Testimonials Regarding Peter Redpath's ASL Program about "The Organizational Genius of St. Thomas Aquinas":

Peter DeMarco, Founder and CEO, Institute for Priority Thinking, LLC:

“Peter Redpath's teachings about 'The Organizational Genius of St. Thomas Aquinas' are the reason for my success as a leadership coach and budding ethicist in business.”

Andrew Gniadek, Graduate of Holy Apostles College and Seminary Christian Wisdom Philosophy Concentration:

“If you want to be a run-of-the-mill leader, continue sitting through those company-paid sessions run by consultants who are essentially snake-oil-fad merchants. If you seek to learn about timeless principles of leadership that will enhance yourself and your organization, and give you a truly competitive edge in business and life, then study, like I did, ‘The Organizational Genius of St. Thomas Aquinas’ with Dr. Redpath. You will not regret it.”

A William McVey, Organizational Consultant in Knowledge and Emergent Behavior:

"For many years, I had worked in the manufacturing world as the CEO of a Total Quality and Knowledge Management consultant organization dedicated in theory and practice to W. Edwards Deming’s ‘12 Principles of Management.’ I had spent time studying with Deming, and had heard him often express that corporate management required a theory of profound knowledge. Near the end of his career he realized that creation of an organization dedicated to quality required more than the statistical and process tools of TQM, and he started to call for a new type of leadership grounded in an Aristotelian concept of causation and a psychology of excellence."

Five years ago, as I was attempting to develop a new cadre of Deming consultants, I was led by a colleague to the writings of Peter Redpath and have worked with him at his Aquinas School of Leadership since then as he has developed his Thomistic metaphysics of organization and organizational and moral psychology.

As an organizational consultant of the Deming and Drucker schools, I am most indebted to Dr. Redpath. His work in the Metaphysics of Organization and Organizational Moral Psychology have profoundly enriched my understanding of knowledge management. His teachings about the metaphysics of organizational principles are crucial to understanding ‘emergent organizational development.’

I believe the great minds of organizational management of the 20th century (Peter Drucker, Chester I Barnard, and W Edwards Deming) would have enjoyed and celebrated Redpath’s groundbreaking educational program on ‘The Organizational Genius of St. Thomas Aquinas’ as surpassing some of their own teachings.
