Someone who knows himself is confused at the instant of time that he is confused, is really intelligent and educated. Someone who pretends to be well versed infact if he is confused, is not well educated. So, ............. Remember that 2 + 2 = not always 4 , but, its our perception. I consider when something is 4 then, the truth lies between 3.5+ to 4.5- .... this is how education matters. GP
