| The logical term 'subjectal abstraction' here requires a
| word of explanation;  for there are few treatises on logic
| which notice subjectal abstraction under any name, except so
| far as to confuse it with precisive abstraction which is an
| entirely different logical function.  When we say that the
| Columbia library building is 'large', this remark is a result
| of precisive abstraction by which the man who makes the remark
| leaves out of account all the other features of his image of
| the building, and takes the word "large" which is entirely
| unlike that image -- and when I say the word is unlike the
| image, I mean that the general signification of the word is
| utterly disparate from the image, which involves no predicates
| at all.  Such is 'precisive abstraction'.  But now if this man
| goes on to remark that the largeness of the building is very
| impressive, he converts the applicability of that predicate
| from being a way of thinking about the building to being
| itself a subject of thought, and that operation is
| 'subjectal abstraction'.
