A young woman faces the decision of whether to marry a certain man whom she loves but who has deeply rooted, traditional ideas concerning marriage, family life, and the roles of men and women in each. A sober assessment of her future tell the woman that each of the two alternatives offers real but contrasting goods. One life offers the possibility of a greater degree of personal independence, the chance to pursue a career, perhaps more risk and adventure, while the other offers the rewards of parenting, stability, and a life together with a man whom, after all, she is in love with. In order to choose in a self-determined mode the woman must realize that the decision she faces involves more than the choice between two particular actions; it is also a choice between two distinct identities. In posing the questions "Who am I? Which of the two lives is really me?" she asks herself not a factual question about her identity but a fundamental practical question about the relative values of distinct and incommensurable goods. The point I take to be implicit in Tugendhat's (and Fichte's) view of the practical subject is that it would be mistaken to suppose that the woman had at her disposal an already established hierarchy of values that she must simply consult in order to decide whether to marry. Rather, her decision, if self-determined, must proceed from a ranking of values that emerges only in the process of reflecting upon the kind of person she wants to be.
