at war with ourselves

It is quite horrifying, so we tend to avoid thinking about it. We are calling it several names, but it never registers as variations of the same old thing. Heraclitus, 2500 years ago, had said that "War is the Father of all things", an axiom that we tend to discard, because we don't want any bloody war! A bloodless war in this case, is called marketing. It might also be sport-games. Or politics. Or whatever. We make weapons, toys, ideologies and brands. We can't stand the sight of physical brutality so we make it psychological, fighting for imaginary credit values. Fighting against War and against ourselves.
Isn't this the higher purpose of Art and Design, to make War constructive instead of destructive? Can it be that branding, although originally meaning fencing of sorts, is actually the best means we have to satisfy that bloody thirst of our species for War, peacefully?
