Note 5 to Chapter 1 of the author's Mill on Liberty, which Yale University Press published in 1975. It has been included in the Victorian Web with the kind permission of the author and of the Clarendon Press, which retains copyright.
See: J. L. Mackie, Ethics, Ch. 6, Jonathan Glover, pp. 62-6, and J. J. C. Smart. Smart refers to "satisfaction utlitiarianism" instead of "preference utilitarianism". For useful discussions of utilitarianism in general see: J. J. C. Smart / Bernard Williams, and Dan W. Brock. A useful collection of essays on utilitarianism with particular reference to Mill is Mill: Utilitarianism, with Critical Essays.
