“An act of conscience describes an action motivated by loyalty to a conviction, but it usually requires the defiance of other loyalties . . . Press's real achievement in this short book is not in his research or analysis, but in his refusal to flinch from that disquieting fact . . . He knows that those who act bravely are all the more likely to feel anguished, since they know what's at stake. In some ways this book is a thoughtful gesture of support. That might sound like a small thing, but it's not.”—Louisa Thomas, The New York Times Book Review
