Book excerpt: Within the philanthropic sector, as never before, time is of the essence. That is, temporal considerations—questions of intergenerational ethics, of the merits of giving now versus giving later, of the benefits and perils of perpetuity—have gained greatly in prominence. Bringing together the most esteemed contemporary scholars of philanthropy, Giving in Time provides the first sustained analysis of the complex issues surrounding the temporal dimensions of voluntary giving. Incorporating the perspectives of political scientists, historians, legal scholars, and philosophers, the contributors tackle critical questions confronting a new generation of philanthropists in a way that will appeal to academics and practitioners. They take on questions such as: What are the historical and moral foundations for establishing perpetual foundations? What are the leading challenges to philanthropic perpetuity? What is the significance of the recent trend toward “Giving While Living,” the calls to give not through bequests but in one’s lifetime? What are the ethical arguments for giving now rather than giving later? What is a giver’s responsibility to his current moment in time versus his obligation to the future? How does the legal framework supporting and structuring philanthropic practice shape approaches toward giving in time? How should it?
