Practical Ethics

Peter Singer applies a preference utilitarian framework to contemporary moral dilemmas, arguing that ethical decisions should maximize the satisfaction of the interests of all affected beings. He rejects speciesism, asserting that the capacity to suffer—rather than intelligence or human DNA—is the baseline for moral consideration. The text analyzes specific issues including the killing of non-human animals for food, the ethics of abortion and euthanasia, the obligation of wealthy nations to provide famine relief, and the environmental responsibilities of individuals.

This book serves students of philosophy and activists seeking a logical foundation for secular morality. Readers use these arguments to reassess their personal consumption habits and philanthropic commitments. By engaging with Singer’s logic, the reader acquires a systematic method for evaluating harm and benefit, resulting in a clearer understanding of how individual actions impact global suffering and social justice.
