It is seen that the sensations furnish the raw material. Ignoring the few exceptions we may then say that a percept is a made-over group of sensations; a concept a thought-made group of percepts; a judgment a thought-made group of concepts; an inference a judgment derived from other judgments. _Developed thinking_ is first found in the concept, and as we study the thought products, “concept,” “judgment” and “inference,” the truth is forced upon us that _thinking as a process aims to group the many into one_. From many percepts is built the one concept, from two concepts is built the one judgment and from two judgments is built the one inference.[3] Speaking figuratively, thinking is a matter of picking up the fragments along the shore of consciousness and tying them into bundles. =7. THOUGHT IN THE SENSATION AND PERCEPT.= So far in this discussion it has been assumed that there is no thinking involved in the sensation or the percept. There are good authorities, however, who insist on dignifying the sensation, even with a crude form of thinking. To illustrate: One may be reading an interesting novel. The mind is being entertained and ignores the activities of the objective world, yet we cannot say that the mind is dead to the world outside. There is a dim consciousness of certain noises without. These unlocalized sounds are sensations; but how is the mind able to recognize them as sounds or noises? To interpret the noises is it not necessary for the mind to affirm a connection between them and some past mental experience? Is it possible for the mind to know anything without establishing some kind of connection between the outside occurrence and an inner situation? If this is granted then in sensation there must be implicit thinking.
