238 ANTIENT METAPHYSICS. Book III. 



raid, it appears that this difeafe of enniii is univerfal among men, 

 and therefore muft proceed from fome caufe that is congenial or ef- 

 fential to the fpecies ; And the queftion is, what that ca»fe is. One 

 thin"- is evident, that the caufe muft be in the mind ; for it is a dif- 

 eafe not of the body, but of the mind. The reader, therefore, muft 

 attend to the diftindlion which I have made in other parts of this 

 work betwixt mind and body. Mind, I have faid, is the only ac- 

 tive being in this earth or in the univerfe ; and body is only paflive, 

 that is, a fubjed upon which mind adts ; and it is altogether inadive, 

 the vis inertiae^ as it is called, being eflential to it. Mind I have di- 

 vided into two fpeciefes ; that which thinks and reafons, and that 

 which moves body and produces all thofe motions by which the bufi- 

 nefs of nature is carried on. I fay, therefore, that as body by its 

 nature is paflive, fo mind is by its nature adive : Nor can we con- 

 ceive mind to exift without ading ; whereas we can conceive 

 body perfedly at reft, if it be not moved internally by mind 

 or externally by the impulfe of other bodies. In our little world 

 there are three minds, the animal, vegetable, and intelledlual. The 

 animal carries on all thofe operations in our body, which are necef- 

 fary for its economy and prefervation, by moving the fluids that are 

 in it, and performing the other motions which are neceflary to enable 

 man to anfwer all the purpofes for which he is deftined in this life : 

 The vegetable mind concods and digcfts our viduals, and in that 

 way nourifties us and makes us grow : Our intelledual mind diredts, 

 and as it were fuperintends the operations of the other two minds, 

 and fees that they are properly carried on, and, where there is any 

 thing wrong in thofe operations, corredls and amends it. And not 

 only does it in this way dired the operations of our other two minds, 

 but it conduifts other operations in nature, fuch as are neceffary for 

 the fupport of our animal life ; by which I mean the neceflary arts 

 of life, as agriculture, metallurgy, and building, arts too of conve- 

 nience, eafe, and pleafure : It condads alfo the motions of bodies 

 by which the fine arts are produced ; and in fhort there is no mo- 

 tion
