TH E word aflbciation was, I believe, firft ufed 

 in this fenfe by Mr. Locke ; the doctrine is not- 

 withftanding very ancient. Plato and Ariftotle in 

 many of their writings, evidently allude to this con- 

 nexion of ideas. Some of the Stoics remark its 

 effects in fpeaking of cuftom, opinion, &c. and Anto- 

 ninus is very dear upon the topic *. Hobbes has a 

 whole chapter upon the train of ideas f , and makes 

 confiderable life of the doctrine through the whole of 

 his work.

 f ould feem more impertinent than to a(k, as one did, what was the 

 value of a Roman penny ? Yet to me the coherence was manifeffc 

 enough. For the thought of the war introduced the thought of 

 the delivering up the King to his enemies ; the thought of that* 

 .brought the thought of the delivering up of Chrift; and that again 

 the thought of the thirty pence, which was the price ofthattrea- 

 fon: and thence eafily followed that malicious queftion; and all 

 this in a moment of time ; for thought is quick." Leviathan,
