Calls for taking a long-term view towards global problems such as climate change and poverty are familiar, typically urging us to plan on a scale of decades or perhaps a century. By contrast, longtermism asks us to take seriously the idea that what we should do right now may depend on the effects of our actions thousands, even millions, of years into the future. Essays on Longtermism brings together leading scholars to discuss four sets of overlapping questions raised by the longtermist approach. First, should we accept some version of longtermism? Second, to what extent can we predict and control the far future? Third, which ethical priorities are recommended by longtermism, and how revisionary are they? Finally, what implications would longtermism have for the design or reform of social, political, and legal institutions? Contributors, who include both supporters and critics of longtermism, are drawn from a range of disciplines including philosophy, economics, psychology, law, political science, and mathematics, and from private industry.

This Element provides an opinionated survey of the ideal and non-ideal theory debate in political philosophy. It adopts a minimal conception of ideal theory as "theorizing that aims to characterize ideal or perfect justice" and then investigates four major questions. First, does ideal theory provide a benchmark for evaluating what is more just than what? Second, does it provide a target for long-term reform? Third, does it provide a gauge of appropriate or permissible responses to injustice? Fourth, to what extent should we do ideal theory? The core message is that ideal theory is not uniquely or especially well suited to serving these roles, and deserves no pride of place in the discipline. Nevertheless, ideal theory is somewhat valuable and it should remain one active research program among many. Connections to related debates beyond political philosophy are briefly explored.
