GENERAL REMARKS UPON THE FIVE CATEGORIES. 
1. The location of the principles active in producing legitimate 
discrepancy is an experimental process, of varying difficulty at its 
successive stages. The categories, in the order of location by the author, 
were: Ist, Whole and Part, or Rule and Exception; 2nd, Reopened 
Transactions; 3rd, Difference or Degree of Interest; 4th, Apparent 
Identity; and 5th, Coincident Transactions. The first and second, in 
the order named, were almost self-evident, the third was located with 
considerable ease, and the fourth with some difficulty. At this stage 
there remained several cases of discrepancy, legitimate indeed, yet 
not classified and apparently not classifiable. After a considerable 
interval, the discovery of Case 13, however, brought out clearly the 
principle of Coincident Transactions; and to this category the several 
cases, which previously had seemed to be erratic, were found to belong. 
All the cases of legitimate discrepancy found by the author since this 
stage of classification was reached, belonged to one or other of the 
five categories. The discovery of a case which does not belong to them 
should form a stage towards the location of a fresh category.1 There 
is, however, no virtue nor scientific gain in seeking to multiply unduly 
the number of categories by an over-refinement in analysis. 
2. In classifying a discrepancy, there may be a mixture of cate- 
gories, yet not of sufficient importance to require mention of more 
than one category. Thus, in Case 8, with respect to the question 
whether B had or had not read all the Bible, there is in B an element 
of Degree of Interest operating to the exclusion of such particulars as 
the few chapters at the opening of Chronicles, except where the attitude 
of the inquirer appeared to require a contrary course. The discrep- 
ancy is, however, sufficiently classified under the category of Whole 
and Part, or Rule and Exception alone. 
3. Difference of standpoint, a feature common to all the dis- 
crepancies in all the categories, should be distinguished sharply from 
the category of Difference or Degree of Interest. A difference of stand- 
point may produce various sorts of difference in interest; but only 
when there is an appreciable difference in the main interest of the - 
respective statements does the discrepancy belong to the category of 
Difference or Degree of Interest. Thus in Case 5, which is concerned 
with B’s usual place of dining on Sunday as opposed to other days of 
the week and is placed accordingly in the category of Whole and Part, 
or Rule and Exception, the difference in day involves a certain difference 
of interest, but the principal interest in both statements is in the usual 
! See Appendix A, p. 171.
