434 THE PHILOSOPHY 



ftrong averfion to one another, man could not derive fo many ad- 

 vantages from them. Horfes, oxen, fheep, &c. by browfing pro- 

 mifcuoufly together, augment and meliorate the common pafture. 

 By living under the fame roof, and feeding in common, this aflbci- 

 ating principle is ftrengthened and modified by habit, which often 

 commences immediately after birth. A fingle horfe confined in an 

 inclofure, difcovers every mark of uneafinefs. He becomes reftlefs, 

 neglefts his food, and breaks through every fence in order to join 

 his companions in a neighbouring field. Oxen and cows will not 

 fatten in the fineft pafture, if they are deprived of fociety. 



From the fafts and remarks contained in this chapter, it feems to 

 be evident, that the principle of affociation in man, as well as in 

 many other animals, is purely inftindtive ; and that this principle 

 may be ftrengthened and modified by the numberlefs advantages de- 

 rived from it, by imitation, by habit, and by many other circuia- 

 ftances.
