To agree with insanity means to accept the world as man perceives it. To accept insanity means survival, because the last consequence of non acceptance would be suicide.

But the idealist is, in the most cases, not willing to bear the last consequences, this finds exemplifications , among others, in human relations, in war or simply by the poor performance of city-planning in the west. Hence, the human, which is unable to adjust itself to madness, will feel misunderstood, occasionally he will be furious and sometime he will find tears in his face.
