Editor’s note: We approached Ruth Pluznick to write a review of Simon Weisenthal’s book, ‘The Sunflower: On the possibilities and limits of forgiveness’ because we believe its subject matter directly relates to the issue of responding to trauma. Responses to trauma do not only involve questions of healing, but also questions of justice. Both the content and style of this book seem highly relevant to our field and Ruth makes some of these links at the end of her review. While Ruth was writing this piece, Simon Wiesenthal died at the age of 96. It seems all the more appropriate to include this review of his book in these pages.
