ITS EXPRESSION.

WORDS OR IDEA-SYMBOLS. 
Words express ideas versus things. 
When, as often happens, an idea is the mental counterpart of 
a thing, it is true that the sign of the idea is also, indirectly, the 
sign of the thing., Bint it is more accurate and, in close exami¬ 
nation of language, quite essential, to recognize in words the 
immediate signs of what is mental only. 
A word mag express one idea. 
As to what constitutes a single idea, opinion may vary. But 
presumably the idea suggested by “blue” or “blueness” will be 
accepted as single. Its presentation by a single word may be 
described as Integral symbolization. 
A word may express more than one idea. 
Bor instance “ate” expresses not only the idea of eating, but 
also a time idea, and quite as effectively as the phrase “in past 
time.” Such symbolization may be known as Multiple. 
A word may express less than one idea. 
That is, in particular, it may co-operate with another word in 
expressing one idea. Thus in French the symbols “ne” and 
“pas” accomplish together no more than the English “not.” 
The symbolization of each may be distinguished as Fractional.
