Public policy decisions made by the present generation may have a profound impact on future generations. That possibility calls into questions the nature and extent to which the present generation has obligations to future generations. This work starts with the notion of whether there is am obligation to have future generations. It then discusses the various theories that have been put forward regarding obligations to future generations. Theories are divided into major types, identifying the features of each type. Each type is then critiqued, identifying the major problems with each. Arguments against obligations to future generations are examined. A discussion of how obligations to future generations might be accomplished within the context of a democratic society is presented. Finally, a partial solution to the problem of obligations to future generations is posed in the form of Theory Y. Theory Y is discussed in the context of whether it can meet the objections raised against the other theories presented. The nature of Theory Y and its implications for public policy are discussed.
