This edited volume identifies and establishes the idea of the Callidocene, which the authors position as an epoch that both includes and extends beyond the current conception of the Anthropocene. While the word ‘Anthropocene’ has become strongly associated with concerns over humanity’s impact on the planet, contributors turn instead to the Callidocene—intended to encompass human, machine, and system cleverness— to emphasize the hopeful and positive aspects of human influence on the world. Contributors posit that designers in particular have increasingly attempted to consider the impact of their work on society, culture, and the environment, and this book will contribute to this conversation through its analyses of a wide range of topics, including complexity in design, media toxicity, and community innovation in sustainability. Collectively, contributions to this volume highlight the potential of human cleverness to address - or even reverse- the damage we’ve inflicted on both ourselves and our planet. Scholars of sociology, environmental studies, cultural studies, media studies, and communication will find this book of particular interest.
