the other out. In both cases, then, the thought-result is the 
same. The terminology of the first view being simpler, that 
view will be used in this investigation, as a working hypothesis. 
That is, every thought-connective will be treated as not merely 
necessitating, but as accomplishing of itself the reinstatement 
of a former thought. 
PART II. APPLICATION OP THEORY. 
The remainder of this investigation endeavors (I) to general¬ 
ize, for the single thought-relations expressed by the English 
language, the opinion derived from the examination of the word 
“ therefore;” (II) to exhibit the use of the connective in the expres¬ 
sion of multiple relations; (III) to apply the present view to 
the serial relations which occur in what is known as continued 
reasoning. It takes into consideration the connectives listed on 
page 178 of Prof. E. H. Lewis’ “History of the English Para¬ 
graph. ” Prom this list, however, there have been omitted the 
following as of doubtful connective value: yea, nay, first, add to , 
so far, hitherto, thus far, once more, it is true, at least, finally, at 
last, at length, well. On the other hand, a few have been added 
which seem not to have occurred in the texts examined by Prof. 
Lewis. 
I. SINGLE RELATIONS BETWEEN THOUGHTS. 
It is preliminarily assumed that in all cases the function of 
the thought-connective is to exhibit relation between the thought 
of the moment and a preceding thought. This is but saying 
that the connective aims to show what, in popular parlance, two 
thoughts have to do with each other. This being admitted, it 
is obvious that the study of connectives is first of all a study of 
relations. To simplify this study it is desirable to classify such 
relations as are presented by thought-connectives. The diffi¬ 
culty of such classification may be inferred from Lloyd Morgan’s 
belief that the ability to fasten the attention directly upon rela¬ 
tions is the one power which distinguishes the minds of men 
from the minds of other animals. With man himself the power
