the six senses
Note by H Craik to chapter 11 of Tale of a Tub

And note Including Scaliger's. This refers to the elder Scaliger, who speaks of the sextus sensus in his book De Subtilitate addressed ad Hieronymum Cardanum (see Exercitatio 286, 3). The allusion is to the sexual passion. This somewhat sarcastic reference was doubtless suggested by the frequent mention, throughout the controversy, of the younger Scaliger, who had been attacked by young Boyle in his Phalaris , and whose name had been mentioned with respect by Bentley — the only Englishman of the day who could really appreciate the range and grasp of the Scaligers' scholarship. The current estimate of the day in England rated the Scaligers as whimsical pedants. Butler, in Hudibras, refers with something of a sneer to the younger Scaliger's labours in chronology (P. II, c. iii. 1. 881). There is a touch of bitter sarcasm in the Battle of the Books, where Swift makes Scaliger, even though fighting, like Bentley, on the Modern side, yet turn upon Bentley with the most contemptuous abuse (p. 223).
