Peter Hare's long collaboration with Edward Madden on the problem of evil made significant contributions that scholars pursuing the issue must continue to acknowledge. In their articles and book-length treatment of the subject, Hare and Madden provide both a thorough synthesis of historical debate, but also make new inroads calling out what they call "evaders and deniers" of the problem, and showing why the problem can be neither evaded nor denied by modern theists, as well as confronting head-on faults they recognize in both modern "quasi-theist" attempts to resolve the problem, and those of traditional theists.
