Men often behave badly, and it's easy to assume that's just the way they are. Some can be grandiose and aggressive; many others are good guys but emotionally absent and relationally disappointing. Psychologists Charlie Donaldson and Randy Flood contend, however, that most men's behavior is neither capricious or malevolent, but a product of a socialized disorder "mascupathy" - an exaggeration of the genetically masculine traits (aggression and invulnerability) and minimal expression of inherently feminine characteristics (openness and sensitivity). Committed to helping men achieve rich, engaged lives, the authors propose a revolutionary way to think about men. Mascupathy shines a bright light of understanding, revealing unexpected transformations of men in stirring clinical accounts. This is an eye, mind, and heart-opening book full of compelling reasons to feel optimistic about the future of men and the people who love them.
