and, idly* When two trains of ideas occur, directing 

 the attention to one in preference to the other. The 

 order of time, place, &c. have great influence in re* 

 collection. 



In recollecting a company, we are obliged to have 

 refpect to the order of place, to the courfe .of.conver- 

 fation, or fome other of the common relations. > Re- 

 collection in order of time happens from Ib'me part of 

 two ideas becoming entangled with each other, as the 

 inind, when waking, is feldom without ibme idea, fb 

 no one is perfectly gone before the introduction of ano- 

 ther. Recollection from place happens by the tranfi- 

 tion which the mind makes from the firft idea to the 

 place, and from the place to the fecond idea it is 

 the fame in recollection from refemblance. Recol- 

 lection from caufe and effect is the fame as recollection 

 in order of time 3 only it is to be remarked, that we 

 look upon every thing as being both a caufc and effect 

 of fome other thing, though of what, or in what man* 

 ner, we may be ignorant ; and this is the refuk of ex- 

 perience. 



An idea frequently recollected becomes aftbciated 

 with a number of other ideas in the different repetitions 

 of it ; it will therefore be more predominant, and more 

 apt to be recalled on future occafions ; and this con- 

 ftitutes the power of habit over our turn of thinking, 

 which may be acquired from reading frequently the 

 fame book, orconverfing much with the fame pedbn. 



Diftinct memory thus depending on affociation, the 

 fimple ideas are often found to remain, while the cir- 

 cumftances firft connected with them are utterly Lft. 

 Thefe the mind forming into new combinations, we 

 call invention. 



As memory is fo much dependant on aflbciation, k 



is evident, that what influences the latter will have
