Hungarian writer Róbert Horváth finds that Against the Modern World, by Mark Sedgwick (Oxford University Press, 2004), strangely purports to present a history of Traditionalism, yet the book contains very little of real substance regarding the ideas or writings of the central figures on whom Sedgwick focuses. In addition, Sedgwick has overlooked significant historical precedents before the appearance of Guénon, to whom he traces most of the origins of Perennialism/Tradionalism. The reviewer cites numerous flaws in the content and method of the book, and concludes that it is "practically…a gossip book, nothing more than a new false history."

Michael Fitzgerald's review of Mark Sedgwick's Against the Modern World is a detailed view of Sedwick's study of the history of Traditionalism, taking the author to task for shoddy scholarship and research, possible bias, sensationalization for the purpose of marketing, unsupported conclusions, and, most fundamental of all for a writer undertaking such a project, "a flawed understanding of Traditionalism."

Against the Modern World, written by Mark Sedgwick in 2004, has received much criticism for its lax scholarship. This review adds more detail to the criticism, revealing the extent of Sedgwick's shoddy scholarship, misrepresentations and distortions (intended or unintended), self-contradictions, and lack of clarity in use of terminology. The reviewer concludes that, in short, Sedwick is "unable to comprehend the core elements of his study," which inevitably would result in such a work, which purports to be much more. The review includes some important corrections and clarifications, which would have been of assistance to the work had the author himself been aware of them.

This in-depth review is of the World Wisdom book "Uncompromising Truth for a Compromised World" (by Samdhong Rinpoche, edited by Donovan Roebert). The author was recognized to be the reincarnation of the Fourth Samdhong Rinpoche and he was later elected to be the Kalon Tripa or Prime Minister of the Tibetan Government-in-Exile. The reviewer, Samuel Bendeck Sotillos, summarizes the intent of the various wide-ranging sections of the book and he frequently provides quotes from the Rinpoche to illustrate the themes and tone of the book. The review concludes that "These dialogues with Samdhong Rinpoche will provide substantial support to spiritual seekers as they challenge the very assumptions that are crucial to the current era. In fact [Samdhong Rinpoche] makes it clear that the crisis of the post-modern world is no longer isolated in the West alone; it has become a global issue of paramount concern to all peoples."

This review of the 2007 World Wisdom book The Underlying Religion, summarizes the various sections, highlights some compelling ideas, gives a few quotations, and concludes that "The beauty of this book is that it provides an introduction to the essential features of the Perennial Philosophy in an understandable and digestible depth and format.…"

In Coomaraswamy's own words: “In the first part of this article our intention was to show that what ‘repentance’ really means is a ‘change of mind,’ and the birth of a ‘new man’ who, so far from being overwhelmed by the weight of past errors, is no longer the man who committed them; and in the second part, to outline the doctrine of the duality of mind on which the possibility of a ‘change of mind”’ depends, and to demonstrate its universality; to point out, in other words, that the notion and necessity of a metanoia are inseparably bound up with the formulation of the Philosophia Perennis wherever we find them.”
