System has ambiguity between both self-deception and self-truth.But it is because for good reason which can't be understood by those who had improper psychologically-grown childhood of impatience and being(than prevailing).as sense. Here I am telling the reason why system has ambiguity between self-deception and self-truth. It is because every third party mindset is discrete about why every two persons are self-truthful among themselves if same two persons are self-truthful. And same third party is discrete again why same other two persons are self-deceptive if same both persons are self-deceptive. That means every third party mindset nature in society swings either negative side or positive side about every other two persons minds. Third party mindset is like devil(machine)(beast) which has no discretion about its own.Hence fourth order social comes into prevailance against third party discretion by being discrete to third party discretion towards making third party to weep about its social "crime". That means social fourth person is knowledgeable who appears-as-ignorant by being third party question to third party question towards "making all people as self-knowledgeables than just being self-knowledgeables among all others". Wisdom of fourth person prevails,has to prevail and will prevail over intelligence(questioning) of third party if one inculcates "patience and social sense" by social voice.
