Short essays written and published by the author in different years are collected by him under one cover for no chance reason. No matter what question Singer is asked— from the hypothesis of the existence of a world government to charity, from surrogate motherhood to euthanasia, from vegetarianism to the rights of robots— the core of his reflections remains ethics. The world we live in is changing rapidly. As a result of globalization, the vigorous development of science, and the emergence of new technologies, including social ones, the modern person is often faced with difficult moral choices. How should we behave when facing things that no one has ever encountered before? To approve or condemn phenomena that have no analogues in the history of humankind? For anyone who cares about the fate of our planet and the living creatures inhabiting it, Peter Singer’s book can become a reliable moral compass.
