belief, but also I do not, to my knowledge, even think of be¬ 
lief as part of what I wish to express, that utterance being 
accordingly the faithful indicator of my meaning. 
But in non-poetical speech, as indicated, minimal thought 
of necessity includes belief. The double possibility of includ¬ 
ing, and omitting belief, will not accordingly be found except 
in extended thought, or thought consisting, in other words, of 
two or more constituent minimal thoughts. Confining atten¬ 
tion, as in previous cases, to centro-lateral thought, of which a 
single constituent must—and no other may—contain belief,, 
I note the possibility of making either constituent central— 
the other being lateral—and the corollary possibility of includ¬ 
ing belief in either constituent. 
To illustrate, “It is possible that your son be delayed” ex¬ 
presses an extended thought consisting of two interlocking 
thoughts, which, developed into judgments, may be expressed 
by “Your son is delayed” and “Being delayed is possible.’* 
How, in the extended thought, the once-to-be-expressed belief 
may associate itself with either constituent thought. That is y 
the extended thought may take on either the already noted 
form, expressed by “It is possible that your son be delayed,’* 
or the different form expressible by “Your son is possibly de¬ 
layed.” 
This choice of belief-location is plainly, for the total extended 
thought, a choice of arrangement or architecture—a choice, in 
other words, of structure. Bor each constituent thought, how¬ 
ever, it may be regarded as a choice of materials—that is, an 
election of thought-content, its influence in determining verbal 
forms-to-be-employed being therefore rankable under the pres¬ 
ent title, as an influence of thought-content. 
In linguistic practice, so far as known to me, it has so hap¬ 
pened that only verbal forms possess the power of expressing be¬ 
lief, and, of the verbal forms, those only which are known as 
assertive. Accordingly the presence of belief, in thought to 
be expressed, determines the use of an assertive form of the 
verb. Per contra, the absence of belief restricts the use of
