We love to see superheroes fight, whether to protect innocent people from supervillains or to save the world. But superheroes also fight each other, and if we can look past the energy blasts and earth-shattering punches, we can find serious disagreements over principles and ethics. This was certainly the case when Captain America and Iron Man went head-to-head over liberty and security in Marvel Comics' epic Civil War storyline, a fictional allegory to post-9/11 America (as well as the basis for the third Captain America film). In his latest book, Mark D. White, author of The Virtues of Captain America and editor of Iron Man and Philosophy, carefully leads you through the ethical thinking of the three characters on the front lines of the Civil War: Iron Man, Captain America, and Spider-Man. In his characteristically light and humorous tone, White lays out the basic ethical foundations of each hero's thinking and highlights the moral judgment each must use to put his ethics into action. But also how conflicting principles such as liberty and security must be balanced in the real world, lest both be lost. Written in a style that will be easily accessible to everyone, A Philosopher Reads... Marvel Comics' Civil War will be a fascinating read for diehard comic fans and philosophy buffs, as well as those looking for a simple introduction to philosophical ethics.
