How are We to Live?: Ethics in an Age of Self-interest Peter Singer
This assessment of human nature and society suggests that people who take an ethical approach to life often escape from the trap of meaninglessness so prevalent in modern society, finding instead a deeper satisfaction in what they do than those whose goals are narrower and more self-centred. In spelling out what he means by an ethical approach to life, Peter Singer also challenges the view that selfishness is an evolutionary inevitability.
