Owen—Interrogative Thought—Means of Its Expression. 383 
expressed by “to lead/’ and also all that might be expressed by 
“I believe” (or say “I know”). 
It is obvious that, by further loading sueh a word as “leads,” 
a sentence might, without increasing its bulk, be made to express 
an even larger volume of thought. Indeed, as I believe, it is 
by exactly such an increase of the single word’s expressional 
burden, that the question-forms of speech have been developed. 
To me then obviously the study of interrogative expressions is— 
to imitate the agriculturalist’s “intensive farming”—a study of 
intensive symbolism. 
How symbolism of this order has, in question-forms, attained 
perhaps its: highest development. It can best be understood 
after examining those other grades of symbolism, of which it 
forms the climax. Such examination should be based, I think, 
upon a comparative study of thoughts expressed, to which ac¬ 
cordingly I pass in the following chapter.
