552 APPENDIX.. Chap. IIL 



If it be afkied, what tliis principle of life and motion in the Brute 

 is, which does fuch wonderful things ? my anfwcr is, that it is In- 

 ftind. If it be further afked, what Inftin£l is ? I muft have recourfe 

 again to my antient books ; for I don't know that there is any thing 

 in our modern philofophy which teaches us what Inftintt is, any 

 more than what Intelligence is. But Ariftotle informs me that it is 

 Mind aQing in Bodies organized or unorganized, but without In- 

 telligence. To this principle he gives the name of Nature^ diftin- 

 guifhing it both from God and Man, as I have elfewhere obferved *. 



If a more particular definition of Inftincl is defued, I fay it is a 

 determination given by Almighty Wifdom to the Mind of the Brute, 

 to a£l in fuch or fuch a way, upon fuch or fuch an occafion, without 

 Intelligence, without knowledge of Good or ill, and without know- 

 ing for what end or purpofe he ads. Nor fhould this way of ail- 

 ing appear extraordinary even to a man who is not a philofopher, 

 as we fee exam.ples of it daily in our own fpecies : For a Man, under 

 Hie diredion of another of fuperior underftanding, will ufe means ta 

 aceomplifli an end, without having any idea of either j and, indeed, 



in 



can do bv ovx InttWcCi or Reafon. Many more might be given, particularly with re- 

 fT)e<ft to its direfting the Animal to find out remedies for any difeafes it may have. 

 Upon this fubie<5t, there is an antient treatife publifhed by Fabricius, in his Bibliotheca 

 Graeca^ Vol. iv. p. 296. It is entitled, 5rj^; tiwv xjeT«« «»T<a-«5««5» >cjs« c-vtcvxieiec-^. it is 

 the work of Anatolius, a philofopher of the Alexandrian School, and a cotempovary 

 of Porphyry. There he has collected a furprifing number of inftances of animals 

 finding out their own cures, as we fee the dog does among us. This treatife is com- 

 mented upon by a learned German, one Rendorphius, whofe work Fabricius has 



alfo publifhed. ^The Indians of North America know the virtues of many fimplcs 



that we are ignorant of; and it is certain that they can cure difeafes that we cannot 

 cure. Ncrvv, this knowledge they have got, as I have been well inlormed, chiefly 

 by obferving the inftin£t of Brutes..
