Forms of speech are either ****** or composite.Examples of the latter are such expressions as 'the man runs', 'the man wins'; of the former 'man', 'ox', 'runs', 'wins'.
Of things themselves some are predicable of a subject, and are never present in a subject.Thus 'man' is predicable of the individual man, and is never present in a subject.
By being 'present in a subject' I do not mean present as parts are present in a whole, but being incapable of existence apart from the saidsubject.
Some things, again, are present in a subject, but are never predicable of a subject.For instance, a certain point of grammatical knowledge is present in the mind, but is not predicable of any subject; or again, a certain whiteness may be present in the body (for colour requires a material basis), yet it is never predicable of anything.
Other things, again, are both predicable of a subject and present in a subject.Thus while knowledge is present in the human mind, it is predicable of grammar.
There is, lastly, a class of things which are neither present in a subject nor predicable of a subject, such as the individual man or the individual horse.But, to speak more generally, that which is individual and has the character of a unit is never predicable of a subject.Yet in some cases there is nothing to prevent such being present in a subject.Thus a certain point of grammatical knowledge is present in a subject.
