Flaxman has truly said, that neither mind nor any one of its qualities or powers, is an immediate object of perception to men. These are perceived through the medium of material objects, on which their signatures are impressed. The signs of these qualities are immediately perceived by the senses, and by them reflected to the understanding; and we are apt to attribute to the sign, the beauty which is properly and originally in the thing signified. Thus, the invisible Creator hath stamped on his works signatures of his divine wisdom, power, and benignity, which are visible to all men. The works of men in science, in the arts of taste, and in the mechanical arts, bear the signatures of those qualities of mind which were employed in their production. Their external behavior or conduct in life, expresses the good or bad qualities of their minds. In every species of animals we perceive, by visible signs, their instincts, appetites, affections, or sagacity; and even in the inanimate world, there are many things analogous to the qualities of mind; so that there is hardly anything belonging to mind which may not be represented by images taken from objects of sense; and, on the other hand, every object of sense is beautiful, by borrowing attire from attributes of the mind. Thus, the beauties of mind, though invisible in themselves, are perceived in the objects of sense, in which their beauty is impressed. Thus, also, in those qualities of sensible objects to which we ascribe beauty, we discover in them some relation to mind, and the greatest in those that are most beautiful. Every beauty in the vegetable creation, of which we can form any rational judgment, expresses some perfection in the object, or some wise contrivance in the author. In the animal kingdom we perceive superior beauties, resulting from life, sense, activity, various instincts and affections, and, in many cases, great sagacity; which are attributes of mind, and possess an original beauty. In their manner of life, we observe that they possess powers, outward form, and inward structure, exactly adapted to it; and the more perfectly any individual is fitted for its end and manner of life, the greater is its beauty. This, also, was manifestly Milton's theory of beauty; for, in his unrivalled description of our first parents in Paradise, he derives their beauty from those expressions of moral and intellectual qualities which shone forth in their outward form and demeanor:-- "Two of far nobler shape, erect and tall, God-like erect! with native honor clad, In naked majesty, seemed lords of all, And worthy seemed, for, in their looks divine, The image of their glorious Maker, shone Truth, wisdom, sanctitude, severe and pure; Severe, but in true filial freedom placed, Whence true authority in man; though both Not equal, as their sex not equal seemed, For contemplation he, and valor formed, _For softness she, and sweet attractive grace_."
