SYNOPSIS. 
In the interest of whoever may wish to read this writing by 
titles only, the table of contents should perhaps be supple¬ 
mented as follows. 
The assumption (page ii) that a factor of one thought may 
also be a factor of another thought, reappears (page 111) as the 
more special assumption, that a factor of one thought may also 
at the same time be a different kind of factor in another 
thought. This more special assumption, which leads to call¬ 
ing the word for such a factor a hybrid, is followed by some 
examination of the several possible pairs of factorships (111- 
112), attention to actual hybrids (113-116) being centered on 
verbal hybrids or words which in subordinate syntax operate 
as verbs, while in dominant syntax operating as other parts of 
speech. 
After some comment on the single thinking of what is a 
(common) factor of two thoughts (116-117), some endeavor to 
distinguish actual singleness from the mere identity of twice- 
thought ideas (117-118), and some emphasis of doubleness of 
factorship (118), an examination is made of the thoughts in 
which double factorship occurs (119-125), an effort being 
made to vindicate a point of view from which the speaker senses 
a complex total of thought as, part of it, more and, part of it, 
less the burden of his expressional effort—that is, as partly 
central, partly lateral (and often even partly sub-lateral) to 
his expressional purpose'—senses the complex total, that is, as 
what for convenience may be known as a centro-lateral thought. 
It is further argued (125-134) that the central part of such 
a complex total must consist of three terms only, and that the 
lateral part cannot, without the loss of detailed existence as a 
thought, be operative as a term of central thought (134-139). 
The obvious oneness of the centro-lateral total is explained by 
the interlocking operation of a once-thought factor common to 
both central and lateral parts, and styled the centro-lateral 
factor (140-141), the word expressing which may be a verbal 
noun, a verbal adjective or a verbal adverb. 
In the second chapter, an effort to clear away the embarrass¬ 
ing conception of the infinitive subject as per force accusative
