Book excerpt: Like the great speculators Augustine, Aquinas, and Pascal, Jonathan Edwards treated religious ideas as problems not of dogma, but of life. His exploration of self-love disguised as "true virtue" is grounded in the hard facts of human behavior. More than a hell-fire preacher, more than a theologian, Edwards was a bold and independent philosopher. Nowhere is his force of mind more evident than in this book. He speaks as powerfully to us today as he did to the keenest minds of the eighteenth century.
