Peter Guy Jones’ research interest is the philosophical foundation of the Perennial Philosophy and the relationship of this ancient description of reality with current Western metaphysical thought.

His concern is with the failure of Western thinkers to take mysticism seriously and with the way in which this ideological narrowing of attention renders philosophy in our universities inconclusive and ineffective. He argues in various ways that our world is correctly described by the Perennial philosophy and that what in the Western tradition of thought are called the 'problems of philosophy' are evidence of this and not problems at all.
