Today humanity, as never
before, is split into two apparently irreconcilable halves.
The psychological rule says that when an inner situation is not made
conscious, it happens outside, as fate.
That is to say, when the individual remains undivided and does not
become conscious of his inner contradictions, the world must perforce
act out the conflict and be torn into opposite halves.

Works 9,II, para. 126
