Man's humanness did not emerge by refusing Man's animal heritage, but upon an extension of what it is.
If you suppress it in one form, it merely re-emerges in another form. Man is hardly likely to render arbitrary determinations upon himself!
Perhaps, but Man's humanness is an extension of his animal heritage; it is not an extension of a hole.
The exquisite, precise and concentrated focus of your conscious mind is quite necessary in physical life. It is because of this highly selective quality that you can "tune into" the particular range of activity that is physical.
In their own way, animals also possess this selective consciousness. They also focus their attention in very specific directions, perceiving from a vast general field of perception stimuli that is "recognized" and accepted in an organized manner.
When a man or a woman feels no connection between personal reality and experience and the surrounding world, then s/he loses even an animal's sense of pure competence and belonging.
Animals have a sense of justice that you do not understand, and built-in to that innocent sense of integrity there is a biological compassion, understood at the deepest cellular levels.
Yes, indeed.
In your terms man is an animal, rising out of himself, from himself evolving certain animal capacities to their utmost; not forming new physical specializations of body any longer, but creating from his needs, desires and blessed natural aggressiveness inner structures having to do with values, space and time. To varying degrees this same impetus resides throughout all creaturehood.
Your beliefs form your reality, shaping your life and all of its conditions.
Therefore, it is your moral nihilism that will shape your reality, not the other way around. The animals are not nihilists, nor does man have a need for such an inner structure. Moral nihilism appears to be a rebellion against man's heritage.
