 They constitute, as he says, a “single genus” (1955: 181). He thus apparently thought that the realm of judgment-involving moral experiences enjoys a phenomenological signature—an essence. Of course, even if Mandelbaum is mistaken about the entire range of judgment-involving moral experiences, it might be true that, for example, direct moral experiences enjoy a phenomenal essence. For recent discussions of Mandelbaum on this issue of essence, see Horgan and Timmons 2005, 2008a; Gill 2008; Sinnott-Armstrong 2008; and Glasgow 2013.
