It will, therefore, be unnecessary to go into any 

 detail respecting the history of the school philo- 

 sophy of the thirteenth, fourteenth, and fifteenth 

 centuries. We may suppose it to have been, during 

 the intermediate time, such as it was at first and at

 et ipsi urgebantur." &c. Metalogicus, lib. ii. cap. 10.
