Book excerpt: Uncovering injustices built into our everyday surroundings Callous Objects unearths cases in which cities push homeless people out of public spaces through a combination of policy and strategic design. Robert Rosenberger examines such commonplace devices as garbage cans, fences, signage, and benches—all of which reveal political agendas beneath the surface. Such objects have evolved, through a confluence of design and law, to be open to some uses and closed to others, but always capable of participating in collective ends on a large scale. Rosenberger brings together ideas from the philosophy of technology, social theory, and feminist epistemology to spotlight the widespread anti-homeless ideology built into our communities and enacted in law.

Written between fresh ideas and finished books, Forerunners draws on scholarly work initiated in notable blogs, social media, conference plenaries, journal articles, and the synergy of academic exchange.
