"This book addresses late modern debates in Christian theology over the question of whether knowledge of God is available only through God's gracious self-revelation or through revelation plus philosophy or natural reason. The author examines the position of Reginald Garrigou-Lagrange as an exemplar of the latter, and the countervailing position of Karl Barth as an exemplar of the former, and then shows how Aquinas's grammar of God both dissolves and transcends these contentious debates altogether"--
