The book examines the idea of natural and human kinds as requisite to any thought of heterogeneity and any resistance to neutrality, developed in relation to ecological and environmental issues. The giving of the good is understood in terms of species and kinds, linked with genealogy: family, gender, race, kin, and kind. Levinas's sense of exposure -- expression and proximity -- is interpreted as propinquity. Kinds are interpreted as intermediary figures between histories of domination and celebrations of responsibility, between essentialism and identity politics.
