(no subject)

[timelets]

..the criterion or test of an hypothesis is 

the intelligibility 
                   of the received 
principle of explanation,
                          or its 
unity

(without help from any subsidiary hypothesis)

— the truth 
            of our deductions 
                                from it 
(consistency with each other 
                         and with experience)
— and lastly, 
                   the completeness 
of the principle of 
                    the explanation 
of these deductions, 
               which refer to                              
neither more 
                          nor less 
than what was admitted 
                      in the hypothesis, 

restoring analytically 
                      and a posteriori, 
what was cogitated 
               synthetically 
                           and a priori.
