Do we have responsibilities to inform ourselves of suffering and injustice? If so, what kinds of suffering and injustice are we responsible for perceiving? What are the foundations of these responsibilities, and what does it mean to fulfil them? This book examines these questions and argues that awareness of suffering is an essential but indeterminate moral responsibility of the mind. It is not merely an epistemic excellence or a professional activity to be left to experts, academics, journalists, or activists working to address systemic suffering; it is a moral, civic and epistemic responsibility of all people with mature, functioning minds. Cultivating awareness of suffering means exposing ourselves to a range of documentaries, news programs, narratives, and photography that bring suffering into public view. This practice of gaining awareness is foundational in a caring ethical life and in movements for social justice. It is a catalyst for moral progress, a part of responsible citizenship, and a source of knowledge that is valuable in itself. Yet awareness of suffering can be difficult, uncomfortable, saddening, and perplexing, and this book wrestles with difficulties. It also engages with the politics of sight in arguing for a social transformation in moral perception of human and animal suffering. Awareness of suffering represents an act of epistemic resistance and a rejection of widespread willful ignorance of systemic suffering. Awareness of suffering in systems of production and consumption also encourages virtues associated with ethical consumerism, such as frugality, simplicity, and conscientiousness in consumption.
