ABSTRACT
It is also said that analysis is falsification, that the complex is not equivalent to the sum of its constituents and is changed when analysed into these. In this doctrine, as we saw in Parts I and II, there is a measure of truth, when what is to be analysed is a unity. A proposition has a certain indefinable unity, in virtue of which it is an assertion; and this is so completely lost by analysis that no enumeration of constituents will restore it, even though itself be mentioned as a constituent. There is, it must be confessed, a grave logical difficulty in this fact, for it is difficult not to believe that a whole must be constituted by its constituents. For us, however, it is sufficient to observe that all unities are propositions or propositional concepts, and that consequently nothing that exists is a unity. If, therefore, it is maintained that things are unities, we must reply that no things exist.
