Origin
In medieval natural philosophy, degrees were the successive stages of intensity in which the elementary qualities of bodies (hot, cold, moist, dry) were described. The third degree, out of a normal total of four, was very intense; Shakespeare humorously describes one of his characters as lying 'in the third degree of drink'.

The terminology survives in third degree burns (the deepest variety) and in the (originally American) idea of third degree interrogation, though this may owe something to Masonic ritual. There are three degrees of seniority in Masonic lodges; to become a Master Mason, the highest rank, the candidate must attend an interview which is very hard, frightening and unpleasant. The third degree then, is the interview a man must have before he can become a Master Mason.
