It is often morally important that you have a choice between two options in the sense that each option is available to you and you are not coerced into choosing one or the other. Even when you have a choice, though, the presence of time constraints and other noncoercive influences can prevent you from taking the time you need to make up your mind and really choose for yourself. How are we to understand this latter phenomenon? In this essay, I argue that while choosing for yourself seems, at first glance, to be an exercise in discovering your preferences, this is not the whole story. At least sometimes, choosing for yourself instead involves creating your preferences—and, in so doing, choosing what kind of person and valuer to be—through the exercise of what I call formative autonomy. I then explore some objections to this account and some implications for public health policy and clinical ethics. Throughout, I draw primarily on examples that involve choosing whether to continue or terminate a pregnancy and the regulations governing such choices.
