2. In the first place, the Earth, as the abode of man, the intellectual creature, contains a being, whose mind is, in some measure, of the same nature as the Divine Mind of the Creator. The Laws which man discovers in the Creation must be Laws known to God. The truths,--for instance the truths of geometry,--which man sees to be true, God also must see to be true. That there were, from the beginning, in the Creative Mind, Creative Thoughts, is a doctrine involved in every intelligent view of Creation. 3. This doctrine was presented by the ancients in various forms; and the most recent scientific discoveries have supplied new illustrations of it. The mode in which Plato expressed the doctrine which we are here urging was, that there were in the Divine Mind, before or during the work of creation, certain archetypal Ideas, certain exemplars or patterns of the world and its parts, according to which the work was performed: so that these Ideas or Exemplars existed in the objects around us being in so many cases discernible by man, and being the proper objects of human reason. If a mere metaphysician were to attempt to revive this mode of expressing the doctrine, probably his speculations would be disregarded, or treated as a pedantic resuscitation of obsolete Platonic dreams. But the adoption of such language must needs be received in a very different manner, when it proceeds from a great discoverer in the field of natural knowledge: when it is, as it were, forced upon _him_, as the obvious and appropriate expression of the result of the most profound and comprehensive researches into the frame of the whole animal creation. The recent works of Mr. Owen, and especially one work, _On the Nature of Limbs_, are full of the most energetic and striking passages, inculcating the doctrine which we have been endeavoring to maintain. We may take the liberty of enriching our pages with one passage bearing upon the present part of the subject. "If the world were made by any antecedent Mind or Understanding, that is by a Deity, then there must needs be an Idea and Exemplar of the whole world before it was made, and consequently actual knowledge, both in the order of Time and Nature, before Things. But conceiving of knowledge as it was got by their own finite minds, and ignorant of any evidence of an ideal Archetype for the world or any part of it, they [the Democritic Philosophers who denied a Divine Creative Mind] affirmed that there was none, and concluded that there could be no knowledge or mind before the world was, as its cause." Plato's assertion of Archetypal Ideas was a protest against this doctrine, but was rather a guess, suggested by the nature of mathematical demonstration, than a doctrine derived from a contemplation of the external world.
