Man sees the cosmos naturally. We open up our eyes and there it is. Our nature is such that it corresponds to the cosmos and is proportionate to it. Our nature is to be the cosmos by an immanent act. We are therefore a part of the whole by a perfect correspondence to the whole.
What would the cosmos look like without man? It wouldn’t look like anything. The angels do not need to sense it to know it, and the mere animals do not know it when sensing it. An eagle doesn’t need to relate to the things he sees as “cosmos”- that is superfluous to him. It suffices that he see nest parts, mates and fishes- and he need not see these as any unity. The universality of intellect continually forces us to pull in more and more of the cosmos by physical perception. We have a physical awareness of a physical thing; the universality of the object of our mind (what material things are) perfectly corresponds to the cosmos (we rise above this object not by seein the immaterial, but by a judgment about the material).
