An Argument for Intrinsic Value Monism

In this paper I argue that there is only one intrinsic value (i.e. intrinsic value monism). I start by examining three aspects of values that are often taken to count against this suggestion: that values seem heterogeneous, that values are sometimes incommensurable, and that we sometimes experience so-called “rational regret” after having forsaken a smaller value for a greater one. These aspects, I argue, are in fact compatible with both monism and pluralism about intrinsic value. I then examine a fourth aspect: That a very large amount of any one value can always outweigh a very small amount of any other. I argue that this aspect, which I call the nominal notable-commensuration principle, is compatible only with monism.
