The Dilemma of Freedom and Foreknowledge by Linda Trinkaus Zagzebski

Abstract

714 BOOK REVIEWS learning; the Jesuits lean to the voluntarist. Possessed of a unitary academic model, he is really arguing for Aristotle's analogy of attribution . Apparently, no one of his 200 plus Jesuit contacts told him that Nastri prefer St. Thomas and his analogy of proper proportionality. The historian Daniel Boorstin spent 25 yeari!l writing his trilogy on The Americans. What emerges from this analysis? Boorstin points out that Americans like ambiguity, that they function best amid flux; ambivalence becomes their proper medium. For this reason, I have accepted Nathaniel Hawthorne as our most central writer. He situates American questions within a landscape of chiaroscuro. The Jesuit experience in the United States belongs essentially to the same landscape. But today , as formerly, it remains a landscape of questions. McDonough, on the other hand, has too many certitudes, too many answers, too much high definition-what Henry Adams regards as "mere facts." Instead of illuminating the landscape from within, his study inevitably recedes into the larger ambiguity reserved for what Wallace Stevens has called, " Prologues to what is possible."

As a Christian and a philosopher, Linda Trinkaus Zagzebski wants to understand why it is reasonable to affirm that we remain free despite God's infallible knowledge of our future acts. Moreover, she is not content simply to demonstrate that this affirmation involves no logical con· tradiction, for "reasonable people expect more" (p. 33) than a merely negative result. Hence the author sets herself the more ambitious task of working toward a positive solution that would explain why the compatibility of divine foreknowledge and human freedom is plausible and not a bare logical possibility. The hook sorts out recent opinions on the subject and sketches an original position that she hopes will advance the discussion. Zagzehski begins by constructing the most formidable version of the dilemma. Assuming that God is infallible and essentially omniscient, that the past has a kind of necessity that the future lacks ("accidental necessity"), and that this necessity can he transferred (in some sense) from the antecedent to the consequent of a conditional proposition, the dilemma may he stated as follows: BOOK REVIEWS (1) Necessarily, God believes at time t 1 that I will do S at t 3 if and only if I do S at t 3. (2) It is accidentally necessary at t 2 that God believes at t 1 that I will do S at t 3. (3) If (1) and (2) are true, then it is accidentally necessary at t 2 that I do Sat t 3. (4) It follows that it is accidentally necessary at t 2 that I do S at t 3. (5) But if it is accidentally necessary at t 2 that I do S at t 3, I do not do S at t 3 freely. (6) Therefore, I do not do S at t 3 freely. 715 Much of the first chapter is devoted to establishing that this form of the dilemma is more resistant to solution than any other, especially the so-called problem of future truth. Zagzebski goes on to evaluate three broad approaches to solving the dilemma. In Chapter 2 she takes up the " timelessness " solution. Its proponents, among whom the author numbers Boethius, Thomas Aquinas, Eleonore Stump, and Norman Kretzmann, negate premise (2) of the foreknowledge dilemma by contending that God is not in time. Zagzebski considers this an acceptable negative solution to the dilemma and sees in it the potential to ground a more comprehensive, positive solution. Nonetheless, she refrains from subscribing wholeheartedly to the timelessness solution because it confronts one with a dilemma at least as perplexing as the one it solves. She puts the problem this way: like the past, eternity is fixed, for it is constituted by a state of affairs about which we cannot do anything; therefore my future acts are determined no less by God's timeless knowledge than by God's foreknowing them in a strictly temporal sense. In Chapter 3, Zagzebski considers...
