When we read in the Analysis (p. 265) that "the word _man_ is not a
word having a very simple idea, as was the opinion of the Realists;
nor a word having no idea at all, as was that of the Nominalists"
this language seems to me not well-chosen. {282} As to the
Realists--the Platonic Ideas are conceived as eternal, immutable,
grand, dignified, &c., but Aristotle[l] contends that they cannot
all be simple: for the Idea of Man (e.g.) can hardly be simple, when
there exists distinct Ideas of Animal and of Biped. As to the
Nominalists--we cannot surely say that they conceived the universal
term as "having no idea at all." A doctrine something like this is
ascribed (on no certain testimony) to Stilpon, in the generation
succeeding Aristotle: the word Man (Stilpon is said to have
affirmed[m]) did not mean John more than William or Thomas or
Richard, &c., therefore it did not mean either one of them:
therefore it had no meaning at all. So also William of Ockham is
said to have declared that Universal Terms were mere "flatus vocis:"
but this (as Prantl has shewn[n]) was a phrase fastened upon him by
his opponents, not employed by himself. Still less can it be
admitted that Hobbes and Berkeley conceived the Universal Term as
"having no idea at all." They denied indeed Universal Ideas in the
Realistic sense: they also denied what Berkeley calls "determinate
abstract Ideas:" but both of them explained (Berkeley especially)
that the Universal term meant, any particular idea, considered as
representing or standing for all other particular ideas of the same
sort.[o] Whether this be the best and most complete explanation or
not, it can hardly have been present to Mr. James Mill's mind, when
he said that the Universal term had no idea at all in the opinion of
the Nominalists.
