Legal and social norms regarding gender relations have undergone dramatic changes in the past 25 years. The changes have come about largely because of the confluence of changing economic and technological realities, the unfolding of the norm dictating equal treatment of individuals, the sexual revolution and its corollaries of improved contraception and legal abortion, the rise of women as a self-conscious group and a presence in the academy, and the interrelations of all of these factors. As men and women have come to share dormitories and workplaces, and as the old mores governing sex—and male-female relations in general—have broken down, there has been struggle and uncertainty over what norms should apply to sexual relations.

This article has two broad purposes. First, as a political philosopher who has been interested in the concepts of coercion and exploitation, I want to consider just what the analysis of the concept of consent can bring to the question, what sexually motivated behavior should be prohibited through the criminal law? Put simply, I shall argue that conceptual analysis will be of little help. Second, and with somewhat fewer professional credentials, I shall offer some thoughts about the substantive question itself. Among other things, I will argue that it is a mistake to think that sexual crimes are about violence rather than sex and that we need to understand just why the violation of sexual autonomy is a serious wrong. I shall also argue that the principle that “no means no” does not tell us when “yes means yes,” and that it is the latter question that poses the most interesting theoretical difficulties about coercion, misrepresentation, and competence. In addition, I shall make some brief remarks concerning two questions about consent and sexual relations that lie beyond the criminal law: What “consent compromising behaviors” should be regarded as indecent, although not criminal? When should someone consent to sexual relations within an enduring relationship?

Let me begin by admitting that I am wary of any comprehensive definition of consent. This bias stems from my professional concentration on criminal law, in which nouons of freedom and responsibility play vital roles in a wide range of contexts. In each context, however, one discovers that freedom means something different. A voluntary act is any bodily movement not caused by external force or nervous disorder. On the other hand, a voluntary act, however horrific its results, ordinarily may be punished only if the actor was subjectively aware that the act was wrong. In any event, a voluntary act may be excused as the product of duress if another person procures the actor's cooperation in the crime by an illegal threat that would overcome the resistance of a person of ordinary firmness.

We regularly wield powers that, upon close scrutiny, appear remarkably magical. By sheer exercise of will, we bring into existence things that have never existed before. With but a nod, we effect the disappearance of things that have long served as barriers to the actions of others. And, by mere resolve, we generate things that pose significant obstacles to others' exercise of liberty. What is the nature of these things that we create and destroy by our mere decision to do so? The answer: the rights and obligations of others. And by what seemingly magical means do we alter these rights and obligations? By making promises and issuing or revoking consent When we make promises, we generate obligations for ourselves, and when we give consent, we create rights for others. Since the rights and obligations that are affected by means of promising and consenting largely define the boundaries of permissible action, our exercise of these seemingly magical powers can significantly affect the lives and liberties of others.

One of the dominant themes of the symposium from which this collection of articles arose was the ontological status of consent. Is consent a particular state of mind? Is it the signification of that state of mind via a conventionally recognized act? Or, is consent a normative concept that evaluates not only the presence of a state of mind or act, but also the appropriateness of that state of mind or act in the particular circumstances?
