Passing from Sensation to Perception, we see that the latter interprets the reports of the former. Perception translates into consciousness the impressions of Sensation. Perception, acting through one or more of the mental faculties, gives us _our first bit of real knowledge_. Sensation may give us the impression of a small moving thing--Perception translates this into the thought of _a cat_. Sensation is a mere _feeling_--Perception is the _thought_ arising from that feeling. A Percept is the product of Perception, or in other words, our _idea_ gained through Perception. The majority of our percepts are complex, being built up from a number of minor percepts; as for instance, our percept of _a peach_ is built up from our minor percepts of the form, shape, color, weight, degree of hardness, smell, taste, etc., of the peach, each sense employed giving minor percepts, the whole being combined in the conscious as the whole percept of that particular peach. Brooks says: "All knowledge does not come directly from perception through the senses, however. We have a knowledge of external objects, and we have a knowledge that transcends this knowledge of external objects. Perception is the _immediate_ source of the first kind of knowledge, and the _indirect_ source of the second kind of knowledge. This distinction is often expressed by the terms _cause_ and _occasion_. Thus perception is said to be the _cause_ of our knowledge of objects, since it is the immediate source of such knowledge. Perception is also said to be the _occasion_ of the ideas and truths of intuition; for, though in a sense necessary to these ideas, it is not the source of them. Perception also furnishes the understanding with materials out of which it derives ideas and truths beyond the field of sense. As thus attaining a knowledge of external objects, affording material for the operations of the understanding, and furnishing the occasion for the activity of the intuitive power, _perception may be said to lie at the basis of all knowledge_." Perception is of course manifest in all persons. But it varies greatly in degree and power. Moreover, it may be developed and cultivated to a great degree. As Perception is an interpretation of the impression of the senses, we often confuse the cultivation of Perception with the development of the senses themselves. Two persons of equally perfect sense of sight may vary greatly in their degree of Perception of sight impressions. One may be a most careless observer, while the other may be a very close observer and able to distinguish many points of interest and importance in the object viewed which are not apparent to the first observer. Cultivation of Perception is cultivation of the _mental background of the senses_, rather than of the sense organs themselves. The Perception accompanying each sense may be developed and cultivated separately from that accompanying the others.
