Interesting.
I admire the celebration of man as capable of the Ideal.

Although perhaps since Superman has obvious Christian themes and elements, this could also be used to say that the Perfect Productive Person, even if immortal or more than a Man, is still an ideal of what man is and ought to be?

In some ways, you could say that the closer men are to that Ideal Man, the more reason to celebrate that Ideal as achievable and right.

Although Christians today portray a very different understanding of God (namely an altruist), perhaps if there were other portrayals of a self serving God one could make the parallels between God being glorified and happy when Man, his prime creation, is glorified and happy?

So Superman is celebrated as well as the humans/mortals he is saving, when they also act like him? Although I agree that it is the strength of the creating mind that is most valuable, through which muscles should merely be the outward expression of that inner discipline of thought.
