The second qualification these two share is the love, respect and comfortable rapport of being intimately bonded as father and son. Revel's role here is primarily as the scholar interlocutor with a list of predetermined points designed to draw out Ricard's understanding of Buddhism. He is the clear thinking Western materialist and skeptic. Often he relates his son's responses to European philosophy and psychology from ancient Greek to the modern sciences, and appears genuinely surprised and delighted to learn of Asia/Buddhism's theoretical contributions (to human thought) long before Europe's. He is also quick to point out when Buddhism is merely covering old ground that European philosophy has mined extensively as well. Yet he consistently does this with passion and heart. It is especially touching to see his genuine appreciation of his son's deep and clear understanding.
