Context

“Whether It Is More Grievous to Sin Through Certain Malice Than Through Passion? Objection 1: It would seem that it is not more grievous to sin through certain malice than through passion. Because ignorance excuses from sin either altogether or in part. Now ignorance is greater in one who sins through certain malice, than in one who sins through passion; since he that sins through certain malice suffers from the worst form of ignorance, which according to the Philosopher (Ethic. vii, 8) is ignorance of principle, for he has a false estimation of the end, which is the principle in matters of action.” source
