ABSTRACT
This chapter outlines how to approach the question of duties we owe to future generations using Alan Gewirth's Principle of Generic Consistency (PGC). First it spells out briefly what the PGC prescribes, then outlines two arguments for using the PGC to address practical issues in general, specifying middle-order principles that the PGC supports that are of particular importance in relation to duties to future generations. Against this background, it explains how the PGC counters some problems that have been raised concerning the idea that we have duties to future generations.
