<p>"<i>Conventional and Ultimate Truth</i> by the well-known professor Joseph O'Leary is a major contribution to contemporary Christian fundamental theology. It is original, exceptionally erudite, and often brilliant. This is a genuine contribution to post-Heidegger phenomenology articulating a distinct, unique phenomenology of religion in its plural and complex phenomenality. The book is a splendid achievement." —David Tracy, Andrew Thomas Greeley and Grace McNichols Greeley Distinguished Service Professor Emeritus of Catholic Studies, University of Chicago Divinity School</p>

<p>“This third volume of O’Leary’s trilogy on fundamental theology is a work in comparative theology, engaging key dialogue partners in articulating a distinctive phenomenology of religion. He believes that talk of the ultimacy of emptiness does not produce negative theology but sends one back to the fabric of conventional discourse to enable breakthroughs of ultimacy.” —<i>Choice</i></p>

<p>"Works in comparative theology have begun to capture attention in theological circles, including the works of Francis Clooney, James Fredericks, John Keenan, and an increasing number of younger scholars, all writing with fresh insights in Christian theology as enriched by their intellectual sojourns into a religious tradition other than their own. O'Leary's work can be taken in good company with these works, and is a significant contribution in this regard. It is a 'must-read' for those already engaged in comparative theology, and more so for all those in systematic theology who seek to bring their theological insights into conversation with wider circles of thought." —Ruben L. F. Habito, Perkins School of Theology, Southern Methodist University</p>
