that the Animal Life is a Mind, as well as the Intelic<5lual, being 

 a Snbftance Immaterial, diftind from Body, operating by it- 

 felf, as the Intelledual Mind does, and particularly in Dreams, 

 although being fo intimately united with Body, its operations mud 

 be much ailcdted by the habit of the Body, not lefs, but, I believe, 

 more, than the operations of our Intellect. Acknowledging, there- 

 fore, this influence, I account for its operations, as I do for thofe of 

 Intelledl, from its own Nature, and not from the Vapours and Ex- 

 halations of Body, which may difturb and diftort its productions, 

 but never can be the caitj'e of any of them. 



And here our Materialifts may obferve, with fome triumph, that 

 Ariftotle has been as unfuccefsful as they in accounting for the ope- 

 rations of Mind by Matter and Mechanifm. It may likewife give 

 them fome fatisfa£tion to think, that, in the illuftration, above men- 

 tioned, of his hypothefis of Dreams, he has accounted, as lamely as 

 they do, for the continuation of the Motion of Projedilcs, which, 

 he fays, is caufed by external impulfe ; not, indeed, by the origi- 

 nal impulfe, after it has ceafed, (for of that he does not appear to 

 have had the leaft idea), but by the trufion of the air, one body of 

 air impelling another and fo continuing the Motion ; whereas, if 

 he had ftuck to the Principle of Motion, that, he fays, is in all 

 Phyfical Bodies, which I call the Elementary Mind, and which, he 

 fays, is a fpecies of Mind, and dignifies with the name of Nu' 

 ture, he could very eafily have accounted for the Motion of 

 Projediles, by fhowing that this Mind moves Body in various 

 ways, and not conftantly, but occafionally, as, in this cafe, up- 

 on occafion of the Body. being impelled by another Body ; and 

 in many other inftances, which ek^ive attrnclion^ as the chy- 

 mifts call it, exhibits to us : And this may fcrve to fhow us how 

 true Ariftotle's notion is of the internal Principle of Motion 

 in Bodies, which he has made the foundation of his whole
