"For most of us, the answer is not to start giving everything away. We need to understand how to give — the motivations, circumstances, and practices that will make our giving as effective as possible. It won't be simple, but the research presented in this volume gives us cause for great hope. It tells us that altruism can be learned and cultivated, and that its rewards are profound. We believe we can transform our economic policies and actions into a force for good — a force that fulfills both short- and long-term aspirations for the protection of the environment, material prosperity, and meaningful, personal satisfaction for all."
