The old man clings to the past but tends to lose his grip on it over time. He is set in his ways and a ghost of what once was.
The new man is somewhat of a tyro who wants more but lacks perspective and so has a limited world view. He tends to be more adaptive but suffers from a lack of restraint due to an uncritical nature. Oversimplification leaves him prone to error.
Caesar was a new man who did not respect bounds and ended up with delusions of grandeur. Cicero, also a new man, recognized the need for moderation and balance. He was a rare breed who tried to see both sides but was not fully accepted by either side.
The Renaisance saw a re-emergence of the new man and the beginnings of the Reformation. The spirit of self-determination gained ascendency in northern Europe. In America too there was a break brought about by its treatment as a protectorate by a remote government. America was the New World and its people sought a new beginning. The Enlightenment with its progressive viewpoint had spurred change but the excesses of the French Revolution and the rise of Napoleon raised a lot of doubts.
Perhaps the best approach is that of the "regenerative receiver". He too is no longer satisfied with predetermined solutions and seeks a better picture by reworking the problem. In the process he acquires some knowledge of what is missing. Additional creativity allows one to go beyond what has already been accomplished. A broader perspective takes one beyond the here and now. But the wise man is also interested in bounds.
