SORITES, 2a>pEiT>i?, formed from o-^.p©-, cumulus, heap, 

 in Rhetoric, &c. a kind of argument, in which feveral middle 

 terms are chofen to conneft one another fiicceffively in feve- 

 ral propofitions, till the lalt propofition connects its predi- 

 cate with the firft fubjeft. Whence Cicero calls \t fyllogifmus 

 acervatus, an accumulative fyllogifm. 



Such was that merry argument of Themiftocles, to prove, 

 that his little fon, under ten years old, governed the whole 

 world. Thus : " My fon governs his mother ; his mother 

 me; I the Athenians; the Athenians the Greeks ; Greece 

 commands Europe ; Europe the whole world : therefore 

 my fon commands the whole world." 



This method of difputing prevailed much among the 

 Stoics ; efpecially with Zeno and Chryfippus ; but it is very 

 fophiflical.
