Quote from ‘Chap. XI. On Logical Breadth and Depth’
Two of the most important characters of general terms are their logical breadth and depth. The breadth of a term in general is that of which the term can be predicated. [—] The breadth therefore may be considered as a collection of objects – real things – though it can also be considered as consisting of the terms which may be made subject of a true proposition of which the given term is the predicate.
