If we take the entire universe and the human soul, we glimpse something of the riches of what it means to be human. Put in another way, we can say that the entire universe must be created in order that human beings can be what they are meant to be. We could say that the lack of intensity of the human spirit is the reason for the existence of the material universe. Then the human soul becomes the ultimate foundation for the existence of matter, for it is the final cause of existence of material things, and by giving rise to matter, it in some way gives rise to space and time. But Mersch is not finished.
All men have the same form in the abstract.
In itself, this form is transcendent with regard to its concrete realizations. Therefore the latter must be endlessly multiplied in order to convey as well as possible, although always inadequately, the fullness of humanity that is in the form. The conclusion necessarily flowing from this is that the multiplicity of men is at bottom a unity, and that all men are one through their form. What cannot be expressed once and for all is expressed in a myriad of different ways, so we have many human beings all possessing the same fundamental form, but each embodying a certain realization of it. It Is only in the human race as a whole seen as the culmination of the universe that we can fathom what humanity Is.
