"O Cormac Mac Art, of Wisdom exceeding,
What is the evilest way of pleading?"
Said Cormac: "Not hard to tell!
Against knowledge contending;
Without proofs, pretending;
In bad language escaping;
A style stiff and scraping;
Speech mean and muttering,
Hair-splitting and stuttering;
Uncertain proofs devising;
Authorities despising;
Scorning custom's reading;
Confusing all your pleading;
To madness a mob to be leading;
With the shout of a strumpet
Blowing one's own trumpet."
