The repetition of those blunders which has caused huge turmoil again and again ,but the predisposed state tend to forget too soon and again itch to venture leading to repetition and perplexed state of misery.
Much of causes are hearty apprehended yet no concrete regular steps to address them are difficult to initiate to not endure rigors of cobweb and break mold and become free,the factors that nourish status-quo in deprivation of will and surrender to tendencies knowing/unknowing without way out.
The evolution take shape albeit everything ,it might not had been smooth,haphazard may be due to natural or man made follies ,misguided adventures,but it real test could only be attempted after its full impact pervades all around,here to there are so called different sort of rationalists ,some who found past too sacred and feels present should also molded in it perfectly ,some blame to limited connectivity not allowing sharing of knowledge earlier but to other side of folly appears that more connectivity allows more scope to propagate it farther.
The analysis is based on the perspective of who is attempting it ,individual,group,organisation,nation,society etc ,and if the narrow end of one were met than despite being biggest folly may not termed it so by them,rather may be treated as big achievement.
Therefore one of the biggest follies may appear that to judge it from limited angle/perspective,which is accentuated /aggravated by multiple fold of segregation based on geography,beliefs,boundaries,color,so ultimately bigger folly is that all analysis be based on common people plight,which is routinely evaded, despite being the most significant one.
The folly to qualify as folly in today’s environment of organisation and else need to qualify some ingredients as ,first of all these muse be clearly contrary to the self interest of the organisation or group pursuing them,its like digging ones own base, such action are taken when the door of wisdom are closed and the command passes to such forces.
