A TREATISE 



theonemakethfcience, in the other caufeth naturall trtnfmu- 

 tations. 



Another reflexion, which will be fit for us to make upon thefc 

 long difceurfes, is this, that of neceflity there muft be a joyning 

 of feme things now aftually in our knowledge, unto other things 

 we think not of; for it is mamfeft, that wee cannot at the fame 

 timeaftually think of a whole book of Euclide, and yet to the 

 due knowledge of feme of the lair. Proportions, the knowledge of 

 almoft all the former is required: likewife it is impoffible we 

 fliould at the fame time think of all the multitude of rules belong- 

 ing to any art, as of Grammar, of Metering, of Architecture; and 

 yet when we write in Latine, make a Poemc , or lay the defign 

 of a hoafe, wepraftife them whiles we think not of them 3 and 

 areafliired we goe not againft them, however wee remember 

 them not. 



Nay, even before we know a thing, we feem to know it; for 

 fincc we can have a defireof nothing, but of what weknow,how 

 could we defire to know fuch or fuch a thing , unlefle wee know 

 both it, and the knowledge of it ? And for the moft part we fee 

 a horle, or man, or herbr, or workmanfhip, and by our fenfe have 

 knowledge that fucfy a thing it is, before we know what, or : who, 

 or how, it is: that groweth afterwards out of the diligent obfer- 

 vationofwhatwefee; which is that, whereby learned men dif- 

 fer from the anlearned, for what ftriketh the fenfe , is knowne a- 

 like by them both; but then here is the difference betweene them, 

 the latter fort fitttth ftill with thofe notions, that are made at 

 the firfr, by the beating of our fenfe upon us, without driving 

 them any further : and thofe that are learned doe refolvc 

 fuch com pounded notions , into others made by more common 

 beatings, and therefore more fimple : and this is all the odd es 

 in regard of knowledge, that a Scholler hath of an unlettered 

 man. 



One obfervation more wee will draw out of what wee have 

 faid, and then end this Chapter : it is,how a man doth oftentimes 

 enquire among his owne thoughts, and turncth up and down the 

 itBtges hee hath in his head , and beateth his brains , to call fuch 

 thipgs into his mind, as are ufefull unto him, and are for the pre- 

 fent out of hij memory : which^as we fee it fo necefliry,that with- 

 out it no matter of importince can bee performed in the way
