Certainly this war photograph provokes a feeling of revulsion.  Only the clothes are left.  The photo reminds of many things.

War brutalizes every participant.  Almost every actor involuntarily participates.  War dissolves morality.  What is morality?

What does morality cover up?

Now consider the way ”moral man”
is dressed up,
how he is veiled
behind moral formulas
and concepts of decency –
the way our actions are
benevolently concealed by the concepts
of duty,
virtue,
sense of community,
honorableness,
self-denial
— shou1d the reasons for all this not be equally good?

I am not suggesting
that all this is meant to mask
human malice and villainy
— the wild animal in us;
my idea is, on the contrary,
that it is precisely as tame animals
that we are a shameful sight and in need of the moral disguise,
that the “inner man” in Europe
is not by a long shot bad enough
to show himself without shame
(or to be beautiful).

The European,  (American)
disguises himself with morality
because he has become
a sick, sickly crippled animal that has good reasons for being “tame”;
for he is almost an
abortion, scarce half made up, weak, awkward.

It is not the ferocity of the beast of prey
that requires a moral disguise but the herd animal
with its profound mediocrity, timidity,
and boredom with itself.
