Why are men in charge? After years in the male-dominated field of mathematics and in the female-dominated field of art, Eugenia Cheng has heard the question many times. Cheng argues that her mathematical specialty, category theory, explains why by working more with context, relationships, and nuanced versions of equality than with intrinsic characteristics. Category theory also emphasizes dimensionality: much as a cube can cast a square or diamond shadow, depending on your perspective, so too do gender politics appear to change with how we examine them. Because society often rewards traits that it associates with males, such as competitiveness, we treat the problems those traits can create as male. If we want real change, we need to transform the contexts in which we all exist, and not simply who we think we are.(This book may contain a sharpie mark on the top or bottom edge and may show mild signs of shelfwear.)
