In the faculty of Imagination, both Reason and Memory are, to a certain extent, combined—the mind never imagining or creating objects but such as are analogous to those whereof it has had previous experience. Where this analogy is wanting, the combinations are extravagant and displeasing; and, consequently, in that agreeable imitation of nature, at which the fine arts aim in common, invention is necessarily subjected to the control of rules which it is the business of the philosopher to investigate.

"In farther justification of this arrangement, it may be remarked, that Reason, in the course of its successive operations on the subjects of thought, by creating abstract and general ideas, remote from the perceptions of sense, leads to the exercise of Imagination as the last step of the process.
