Group 'activenny'

I have recently been wandering through the untrodden fields of never afore perceived thoughts traveling along the train which is intended for the conveyance of such neurological frequencies. My thoughts speed incessantly towards one so prominent in history as to uplift the loftiest poet, yet shame, by his character, all those who are in association with his very name, who have wit enough to see his fault[s].

Guess to whom I refer, if you dare condemn one to such a title.
