Proposing to discuss the means of suck a helping in the fol¬ 
lowing chapter, for the moment I describe the telling and what 
is to be told, as another person’s making a conception s uffi cient, 
by linguistic means. Accordingly, as the essential content of 
an interrogative judgment, I rather vaguely nominate “belief 
in truth of desire that by linguistic means another make a con¬ 
ception sufficient.” 
Its distinctive. 
The forms of thought thus far compared—conception, ordi¬ 
nary judgment and imperative—have constituted a crescendo, 
each except, the first containing an element foreign to the form 
preceding. Expecting now, as indicated in my second sentence 
(on p. 354) to find another term for this crescendo, I compare the 
essential content of (1) interrogative with that of (2) impera¬ 
tive. Accordingly, 
(1) “belief in truth of desiring that by linguistic means an¬ 
other make a conception sufficient.” 
(2) “belief in truth of desiring (what is conceived, or say) a 
conception.” 
Subtracting (2) from (1), I obtain as a remainder, “that by 
linguistic means another make sufficient,” or say “another’s 
making sufficient by linguistic means.” This remaining ele¬ 
ment of thought being, as I must believe, in every case an element 
of the interrogative judgment, and never of the imperative or 
any other uninterrogative form of thought, I nominate it as 
distinctive of the interrogative judgment. 
The interrogative accordingly is merely an imperative in¬ 
creased a trifle in complexity—in other words, a pregnant im¬ 
perative. 
Its genera. 
These are naturally based upon the different kinds of insuf¬ 
ficiency which may exist, in a prior conception. 
These kinds of insufficiency—-impedimenta necessary to a 
line of mental march which thus far has been single—it has been 
convenient hitherto to carry in a single' bundle. Henceforth 
lines of reasoning on which I need them are divergent. Let then 
the contents of the bundle be divided. 
These contents, or these kinds of insufficiency, are two. A 
conception may be insufficient because it lacks a conception-
