Singer presents a history of ethical thought, and attempts to refute the popular idea that humans are genetically driven to be selfish. He explains how this idea has been attributed to
Thomas Hobbes and
Adam Smith, and how politicians like
Margaret Thatcher and
Ronald Reagan tried to persuade people that self-interest was good. Singer takes a contrary view, and argues that self-interest is a time-bomb for society. Singer attempts to show how the key for a satisfactory life resides on its purpose and how crucial for that purpose a commitment to an ethical life is. This connects with the argument that the pursuit of self-interest is self-defeating. He argues that
altruism can be genuine – not just
enlightened self-interest, and offers examples of people who sacrificed their lives to save people from
Nazis to make this point. Singer comments on the effect of having the widest perspective possible on our ethical decisions; on how our rational capability sometimes leads us to change our goal; and on the paradoxical opportunity that the existence of so many ills on the world brings to us by way of showing plenty of clearly worthwhile goals. To live a good life, the book prescribes: "You can rethink your goals and question what you are doing with your life. That might mean quitting your job, selling your house, and going to work for a voluntary organization in India. More often, the commitment to a more ethical way of living will be the first step of a gradual but far-reaching evolution in your lifestyle and in your thinking about your place in the world. One thing is certain: you will find plenty of worthwhile things to do." ==Reception==
