| Chapter 11.  On Logical Breadth and Depth (concl.)
|
| If two terms have the same essential breadth or the same essential depth
| logic recognizes no distinction between them.  They are synonimous.  They
| may differ rhetorically.  One of these words may be associated in our minds
| with certain feelings with which the other is not associated but logic has
| nothing to do with such distinctions.  But two terms may be indistinctly
| conceived so that it is not known whether they have the same essential
| breadth and depth or not and in this case the distinction must be
| admitted even in logic.
|
| We now come to the "substantial breadth and depth".
| The substantial breadth is the aggregate of real
| substance of which alone a term is predicable
| with absolute truth.  Substantial depth is
| the real character as it exists in the
| object, which belongs to every thing
| of which a term is predicable with
| absolute truth.
