.—Concerning Imagination.
Imagination is a
faculty of the unreasoning part of the soul. It is through the
organs of sense that it is brought into action, and it is spoken of as
sensation. And further, what is imagined and perceived is that which comes
within the scope of the faculty of imagination and sensation. For
example, the sense of sight is the visual faculty itself, but the
object of sight is that which comes within the scope of the sense of
sight, such as a stone or any other such object. Further, an
imagination is an affection of the unreasoning part of the soul which
is occasioned by some object acting upon the sensation. But an
appearance is an empty
affection of the unreasoning part of the soul, not occasioned by any
object acting upon the sensation. Moreover the organ of
imagination is the anterior ventricle of the brain.
