Hinc raetuunt, cupiuntque, dolent, gaudentque ; nee auras 

 Rcfpiciunt, claufae tenebris et carcere caeco. 



I will add a demonftratlon of the Immortality of mind, taken from 

 Plato, the rather, that it is founded upon the definition which I have 

 given of miiid, and which, as 1 have fhown, is the fame with Plato's 

 definition, viz. that it is what tnoves^ whereas body is what is moved* 

 Whatever, fays he, is moved by any thing elfe, may ceafe to be moved \ 

 and then it ceafes to live, or to be animated : And this is the cafe of 

 body. But mind has a principle of motion in itfelf, and is, by its na- 

 ture, T^^^^zW. Therefore it can never ceafe to move and to a£t^ 

 fmce it cannot depart from itfelf, nor renounce its own nature. — Far- 

 ther, as it is the principle of movement difFufed all over the univerfe, 

 it can have no beginning ; for all things arife from a principle ; but 

 a principle has itfelf no beginning or origin : And, as it had no be- 

 ginning, fo it can have no end ; for, if it were to end, the heavens, and 

 all nature muft ftand ftill, nor could they be again fet in move*' 

 ment *. 



Thus, 



* The paflage of Plato is in the PhaedruSy p. I22i. edit. Ficini. and I will give the 

 reader Cicero's tranflation of it, together with his obfervations upon it — Quod Temper 

 moveter, id aeternum eft. Quod autem motum affert alicui, quodque ipfum agitatur 

 aliunde, quando finem habet motus, vivendi habeat necefle eft. Solum igitur quod 

 fc ipfum movet, quia numquam deferitur a fe, numquam ne moveri quidem definit. 

 Quinetiam caeteris quae moventur, hie fons, hoc principium eft movendi. Principii 

 autem nulla eft origo ; nam ex principio oriuntur omnia : Ipfum autem nulla ex re 

 alia nafcipoteft: Nee e-nim eflVt principium quod gigneretur aliunde. Quod fi nun- 

 quam oritur, ne occidit quidem unquam, Nam principium extindlum, nee ipfum ab 

 alio renafcetur, nee a fe aliud creabir ; fiquidtm necefle eft a principio oriri omnia. 

 Ita fit, ut motus principium ex eo fit, quod ipfum a fe movetur. Id autem nee nafci 

 poteft, nee mori : Vel concidat omne coelum, omnifque natura confiftat, neceffc^ eft, 

 nee vim ullam nancifcatur qua ut primo impulfu moveatur. Cum pateat igitur aeter- 

 num id cfl"e quod fe ipfum moveat, quis eft qui banc naturam animis efle tributam 



neget?
