more judgements to another, e.g. from the two judgements 'Whatever is
made of porcelain is brittle,' and 'This cup is made of porcelain,' we
elicit a third judgement, 'This cup is brittle.'

36. Corresponding to these three processes there are three products
of thought, viz.

(1) The Concept.

(2) The Judgement.

(3) The Inference.

37. Since our language has a tendency to confuse the distinction
between processes and products, [Footnote: E.g. We have to speak quite
indiscriminately of Sensation, Imagination, Reflexion, Sight, Thought,
Division, Definition, and so on, whether we mean in any case a process
or a product.] it is the more necessary to keep them distinct in
thought. Strictly we ought to speak of conceiving, judging and
inferring on the one hand, and, on the other, of the concept, the
judgement and the inference.

The direct object of logic is the study of the products rather than of
the processes of thought. But, at the same time, in studying the
products we are studying the processes in the only way in which it is
possible to do so. For the human mind cannot be both actor and
spectator at once; we must wait until a thought is formed in our minds
before we can examine it. Thought must be already dead in order to be
dissected: there is no vivisection of consciousness. Thus we can never
know more of the processes of thought than what is revealed to us in
