Secondly, a subordinate point in Bradley's logic is that there are
inferences which are not syllogisms; and this is true. But when he goes
on to propose, as a complete independent inference, "A is to the right
of B, B is to the right of C, therefore A is to the right of C," he
confuses two different operations. When A, B and C are objects of sense,
their relative positions are matters, not of inference, but of
observation; when they are not, there is an inference, but a syllogistic
inference with a major premise induced from previous observations,
"whenever of three things the first is to the right of the second, and
the second to the right of the third, the first is to the right of the
third." To reply that this universal judgment is not expressed, or that
its expression is cumbrous, is no answer, because, whether expressed or
not, it is required for the thought. As Aristotle puts it, the syllogism
is directed "not to the outer, but to the inner discourse," or as we
should say, not to the expression but to the thought, not to the
proposition but to the judgment, and to the inference not verbally but
mentally. Bradley seems to suppose that the major premise of a syllogism
must be explicit, or else is nothing at all. But it is often thought
without being expressed, and to judge the syllogism by its mere explicit
expression is to commit an _ignoratio elenchi_; for it has been known
all along that we express less than we think, and the very purpose of
syllogistic logic is to analyse the whole thought necessary to the
conclusion. In this syllogistic analysis two points must always be
considered: one, that we usually use premises in thought which we do not
express; and the other, that we sometimes use them unconsciously, and
therefore infer and reason unconsciously, in the manner excellently
described by Zeller in his _Vorträge_, iii. pp. 249-255. Inference is a
deeper thinking process from judgments to judgment, which only
occasionally and partially emerges in the linguistic process from
propositions to proposition. We may now then reassert two points about
inference against Bradley's logic: the first, that it is a process from
similar to similar, and not a process of identification, because two
different things are not at all the same thing; the second, that it is
the mental process from judgments to judgment rather than the linguistic
process from propositions to proposition, because, besides the judgments
expressed in propositions, it requires judgments which are not always
expressed, and are sometimes even unconscious.
