It’s frequently said that we live in a “post-truth” age. That obviously can’t be true, but it does name a real problem on our hands. Getting things right is hard, especially if they’re complicated. It takes preparation, diligence, and honesty. Wisdom, according to Thomas Aquinas, is the quality of right judgment. This book is about the problem of becoming wise, the problem “before truth.” It is about that problem particularly as it comes up for religious, philosophical, and theological truth claims. Before Truth: Lonergan, Aquinas, and the Problem of Wisdom proposes that Bernard Lonergan’s approach to these problems can help us become wise. One of the special problems facing Christian believers today is our awareness of how much our tradition has developed. This development has occurred along a path shot through with contingencies. Theologians have to be able to articulate how and why doctrines, institutions, and practices that have developed—and are still developing—should nevertheless be worthy of our assent and devotion.
