Sight

Sight is one of the outer powers; it sees and perceives this flower, and conveys this perception to the inner power -- the common faculty -- which transmits this perception to the power of imagination, which in its turn conceives and forms this image and transmits it to the power of thought; the power of thought reflects, and having grasped the reality, conveys it to the power of comprehension; the comprehension, when it has comprehended it, delivers the image of the object perceived to the memory, and the memory keeps it in its repository.
