The conception of social justice presented and defended in Philippe Van Parijs, "Real Freedom for All" entails, among other implication, the justification of an unconditional basic income. It was the subject of seven critical comments that forms issue 22 and part of 23 of ANALYSE & KRITIK. In this article, Van Parijs offers a comprehensive reply.

I argue that Scanlon's Value of Choice View does not offer a plausible account of substantive responsibility. I offer a new account, which I call the Potential Value of Opportunities View. On this view, when a person is in a position to freely and capably make an informed choice, we assess her situation not by the outcome she achieves but by the potential value of her opportunities. This value depends on the value of the various things that she can achieve (...) through her choices, as well as on how disposed she is to choose her better options and avoid her worse options. This view explains the priority we give to preventing harm that a person cannot avoid by choosing appropriately over harm that a person can so avoid by the fact that the second person has a valuable opportunity that the first does not have. It explains the importance of protecting people against choosing badly by the value of being placed in circumstances in which one is disposed to choose well, and the disvalue of being exposed to the danger of coming to harm by choosing badly.

With each of our three criminal-law topics—defining offenses, apprehending suspects, and establishing punishments—we feel, I believe, strong moral resistance to the idea that our practices should be settled by a prospective-participant perspective. This becomes quite clear when we look at how the “reforms” suggested by institutional viewing might combine once we consider all three topics together: imagine a more extensive and swifter use of the death penalty in homicide cases coupled with somewhat lower standards of evidence; or think of backing (...) a strict-liability criminal statute with the death penalty. Of course, such “reforms” would increase the execution of innocents; but, their proponents will tell us, any penal system involves the punishment of some innocents, and, if it provides for the death penalty, the execution of some innocents. Moreover, why is it worse for innocents to be punished than for innocents to suffer an equivalent harm in some other way? Formulated from a prospective-participant perspective: Why not run a small risk of being innocently executed in exchange for reducing, much more significantly, the risk of dying prematurely in other ways?
