any external force ; for every Body muft be moved, cither exter- 

 nally or internally : And, as our Bodies are not moved externally, 

 they muft be moved by fome internal principle ; and that principle I 

 call Mind : And it is in this way, and this way only, that we form, 

 or can form, the idea of Mind moving Body. And by applying this 

 idea to the fcveral motions of the univcrfe, we fhall difcover, with as 

 great certainty as the nature of the thing is capable of, that unorga- 

 zed Bodies are moved by the fame internal principle. And I pro- 

 ceed thus. 



In the //J/? place, I know, by the moft certain of all knowledge, 

 I mean Confcioufnefs, that my Body is moved by this internal prin- 

 ciple. From myfelf I proceed to other men ; and by analogy I con- 

 clude, that their bodies are moved in the. fame manner. By the fame 

 analogy I difcover that the bodies of other animals are moved likewife 

 in that way : And from thence I proceed to the vegetable, whofe 

 motions can no more be accounted for from external impulfe than 

 thofe of the animal : I therefore conclude that they are alfo produ- 

 ced by an internal principle. Nor can I ftop at the vegetable ; but 

 the fame analogical reafoning muft make me conclude, that unorga- 

 nized bodies are moved alfo by an internal principle, fmce their mo- 

 tions cannot be accounted for, any more than thofe of the vegetable, 

 from external impulfe. 



Thus, far, therefore, I think it is proved, by a clear analogy, that 

 unorganized Bodies are moved by Alind ; and, as Mind can move 

 only internally, not externally, or by application of furface to fur- 

 face, as Body moves Body, it is alfo proved, that thofe Bodies are 

 moved by Mind internally. And a like analogy further proves, 

 what I have before endeavoured to eftablifli, that it is not the Uni- 

 verfal Mind that moves thefe Bodies, but a particular Mind ; for it 

 will be allowed by every Body, that it is a particular Mind that
