Deep brain stimulation and wireless deep brain stimulation have the potential to reduce or control violent dispositions. This raises the question of whether enhancing the morality of those who are likely to harm others is ethically acceptable. The implications of controlling harmful dispositions for free will is a feature of the enhancement debate, and it was a feature of worries about other techniques earlier in the twentieth century. In A Clockwork Orange, Burgess expresses the concern that a new technique that controls the violent dispositions of the central character in the book and film, Alex, violates him as a person. This chapter distinguishes a number of worries about the treatment given to Alex, and argues that we should not be concerned that altering dispositions in this way removes free will, if the conditions described in the chapter are met. Neurointerventions to control desires can be ethical when they are consistent with a person’s second-order volitions about the kinds of desires they wish to act upon. So long as a person can genuinely fit new dispositions within a stable self-conception, these new dispositions seem to enable rather than violate their free will.

Abstract This paper presents a new technique for controlling the dynamic response of second-order systems by means of combined displacement and acceleration feedback. The necessary conditions that guarantee the solvability for the problem are formulated. Parametric expressions for the displacement–acceleration gains and the eigenvector matrix are derived. The solution can be applied for the systems with nonsingular or singular mass matrices. Based on the simulation results, we can conclude that the proposed technique is effective.
