ABSTRACT“How should a person lead her life?” The purpose of this paper is to suggest some principles (not a complete list) which will serve us ‘intellectual instruments’ for assessing forms of life. These principles are utilitarian in nature, and, as I will argue, essential to a reasonably rich account of personal well-being. The principles suggested are not instrumental, that is, they determine the worthiness of a form of life led by an agent irrespective of whether it satisfies her existing desires (...) and meet her actual preferences. Hence, I will argue that a person can be deprived, that is, categorically deprived, even when most of her desires are satisfied. In the last section of the paper I will argue for the role of education in ‘initiating’ the agent into worthy forms of life, and hence evading the charge of categorical deprivation and that of irrationality.
