Is Imagination psychologically identical with perception?

Imagination is the faculty of representing to oneself sensible objects independently of an actual impression of those objects on our senses. It is, according to scholastic psychology, one of the four internal senses, distinct, on the one hand, from the sensus intimus, the sensus aestimativus, and the memory, and, on the other hand, distinct from the spiritual intellect. The last distinction is to be specially noted on account of the similarity between the operations of the imagination and certain acts of the intellect. We acquire knowledge of our different faculties only from a study of their operations, and the nature of image is the object of endless controversy. Is it psychologically identical with perception, being differentiated only by lesser intensity? Or, on the contrary, has it a specific nature of its own? It would be hard to say. The problem is very complex and perhaps insoluble.
