A radical reassessment of how we can most effectively help others by a rising star of philosophy and leading social entrepreneur.'A surprising and often counterintuitive look at the best ways to make a difference . . . MacAskill is that rarest of beasts: a do-gooder who uses his head more than his heart.'SUNDAY TIMESMost of us want to make a difference. We donate to charity, buy Fairtrade coffee, or try to cut down on our carbon emissions. Rarely do we know if we're really helping, and despite our best intentions, our actions can have ineffective - and sometimes downright harmful - outcomes. Confronting this problem, William MacAskill developed the concept of effective altruism, a practical, data-driven approach which shows that each of us has the power to do an astonishing amount of good, given the right information.
