This article discusses the views of Immanuel Kant on sexual perversion (what he calls "carnal crimes against nature"), as found in his Vorlesung (Lectures on Ethics) and the Metaphysics of Morals (both the Rechtslehre and Tugendlehre). Kant criticizes sexual perversion by appealing to Natural Law and to his Formula of Humanity. Neither argument for the immorality of sexual perversion succeeds.

This paper is a critical discussion of Simon Blackburn’s recent work on lust. Blackburn develops a view on which lust is decent only when part of a pure mutuality in sex, and is best left alone—we ought not tamper with its “freedom of flow.” I argue that this treatment, which I believe reflects commonly held views, fails in several ways. First, it does not square with the fact that we pursue lust as a good in itself. Second, pure mutuality is (...) hard to come by and almost impossible to recognize, so Blackburn’s account is more restrictive than it may seem. Third, on such a view, masturbation is morally sanctioned only insofar as it mimics real sex; this doesn’t seem right. Finally, such a perspective fits ill with some recent research on the biology of lust in women. (shrink)

Although sexual activity among elderly people remains taboo, residents in eldercare institutions often still have sexual desires, and catering for these desires could improve the quality of life for some of society’s most vulnerable – and most depressed – people. I argue that sexbots are apt to provide such a sexual service. I consider the potential benefits and pitfalls of other sexual possibilities, such as having sex with other residents, nurses, or sex workers, or using sexual aids to masturbation, (...) and I suggest that although some of these have potential, the use of sexbots should nevertheless be considered in addition to them. I address some potential criticisms, including moral objections to sexbots, sex not being a physiological necessity, issues of social justice, and the fact that many others in society do not have their sexual needs catered for. I give some suggestions for safety and dexterity modifications to current sexbots to enable their safe use by elderly people. (shrink)
