{BowMaAn] FUNDAMENTAL PROCESSES IN HISTORICAL SCIENCE 151 
Upon examination it will be found that these five processes are, 
according to the third fundamental principle of science, correct processes 
for formulating trustworthy statements. For it is clear that if a person, 
in formulating a statement, can apply these processes in perfect har- 
mony with their own requirements, so that there will be on his part 
(1) perfect discernment and perfect clarity in his statement, (2) perfect 
success in a serious effort to inform the hearer according to the hearer’s 
interest, (3) perfect impartiality, (4) perfect poise and (5) perfect 
exclusion of all conclusions which he himself can see are unnecessary, 
then such statement will necessarily be absolutely and perfectly correct. 
If he in such an effort to formulate a trustworthy statement fails to 
attain to absolute and perfect correctness, this can only be because he 
as operator, by deviating inadvertently from the requirements of these 
processes, introduced an error into his results. In the processes. them- 
selves, apart from such deviation, there is no room for error. 
Accordingly, on the following two grounds, the one based on the 
example and practice found in actual intercourse and experience and 
the other on a fundamental principle of science, and either of them 
conclusive, these five processes are shown to be correct processes for 
formulating trustworthy statements :— 
1. Because they exemplify the requisites for trustworthiness 
in individuals which, as shown by the experimental test described 
in Section III, are enforced in actual intercourse and experience. 
2. Because they satisfy the requirement of the 3d funda- 
mental principle of science that a correct process is one that rightly 
followed leads necessarily to correct results. 
The function of historical science (Section I) is to formulate state- 
ments that are worthy of belief. These five processes have been shown 
to be correct processes for formulating trustworthy statements, 7.e., for 
formulating statements that are worthy of (trust=) belief. Therefore 
these five processes are shown to be correct processes of historical 
science; and for convenient identification henceforth in this paper they 
will be designated collectively as the five processes of historical science 
and severally as the first, second, third, fourth and fifth process 
respectively. 
(b) THE Four APPLICATIVE PRINCIPLES OF HiISTORICAL SCIENCE. 
For convenient identification henceforth in this paper the four 
principles below enunciated and discussed, relating to the results and 
conclusions that necessarily follow from the exemplification or appli-
