The Commens Dictionary
Quote from ‘Letters to Mario Calderoni’
…although there is but one pure Priman, there are impure and pseudo Primans, as well as Pseudo Secundans. For example, a Leibnizian monad is something which is represented to be all that it is in itself, by itself, and for itself. But this is self-contradictory. If the monad really were for itself alone one could have no more conception of it than one has of the inner life of a pebble on the beach. It would be simply nothing to us. I say, then, that the monad has an “imputed” Primanity, or that it is pseudo-priman. It is represented to be Priman; but, just as being represented, it is really Tertian.
