Wilfrid Sellars characterised the aim of philosophy “(…) abstractly formulated, (…) to understand how things in the broadest possible sense of the term hang together in the broadest possible sense of the term”.
The foundational discontinuity of history and in our current Global “civilisation” (such as it is) that leads us into endlessly futile internecine dissonance is precisely the consequence of a shared poverty in understanding the core axioms of system unity.
The irony here is that any well-informed contemporary philosophy of war and composite analysis of ideological or political difference as conflict will arrive at one enigmatic fact.
That is, the logical self-containment of any sufficiently sophisticated (complex, Global) socioeconomic and cultural system exists as a paradox of recursive self-propagation through difference as entropy.
The self-evident and conspicuous absence of philosophical or political and ideological unity is an indication, not that it can never exist, but that it is of a kind of entity and organisational pattern that is indistinguishable from non-existence.
The more we assert incomplete strategic theorems or information patterns towards structural unity and administrative avoidance of war, the more we guarantee that war is inevitable.
