 As noted above, this last distinction was elided by Ockham, in making the mental act the universal, a name of the things. ‘Man’, he says, signifies Plato and Socrates and all men equally, by virtue of its subordination to the mental act. Once signification is treated extensionally in this way, its only difference from supposition lies in its priority: a general term signifies all those things of which it can be truly predicated (Ockham, Summa Logicae I c. 33).
