When one admits to continuing foolishness he is expressing a state of mind in a high reach of clarity.
Truth is an absolute abstraction.
A consciousness in a state of advanced maturation loses the necessity and even capacity for sequential thought.
It can no longer identify itself in cause and effect relationships.
Its actions become genuinely non-motivated.
The idea that the past has nothing reasonably to do with the present makes no sense to a linear space-time rationale.
In fact, a human definition of rank foolishness would be to find itself in a situation where it could not establish correlating antecedents of thought.
A natural man, then, eventually and inevitably will find a spiritual man foolish.
And finally nothing is more foolish to natural man than a complete commitment to Absolute Truth.
