Madness is not a consequence of uncertainty but of certainty.

To err is nature, to rectify error is glory.

Consequence is no coincidence.

A mistake is only an error, it becomes a mistake when you fail to correct it.

Blessed are the forgetful: for they get the better even of their blunders.

The consequences of our actions take hold of us, quite indifferent to our claim that meanwhile we have 'improved.'
