When principles 
                which are 
                           really regulative 
are regarded 
                  as 
                            constitutive, 
and employed 
                  as 
                           objective principles,
contradictions 
                 must 
                           arise; 


but if they are 
                  considered as 
                                 mere maxims,  
there is no room 
                  for contradictions 
                                      of any kind, 

as they then merely 
                  indicate the different 
                                      interests of reason, 
which occasion 
                   differences 
                                in the mode of thought. 


In effect, 
             Reason has only one 
                                   single interest, 
and the 
           seeming 
                   contradiction 
                                  existing between
her maxims 
              merely indicates 
                                 a difference in, 
and a reciprocal 
                limitation of, 
                                   the methods 
by which 
            this 
                   interest 
                                 is satisfied.”

This reasoner has at heart the interest of diversity — in accordance with the principle of specification; another, the interest of unity — in accordance with the principle of aggregation. Each believes**** that his judgement rests upon a thorough insight into the subject he is examining, and yet it has been influenced solely by a greater or less degree of adherence to some one of the two principles, neither of which are objective, but originate solely from the interest of reason, and on this account to be termed maxims rather than principles.

---Immanuel Kant, “The Critique of Pure Reason.”

**** The two thinkers use different methods of aggregation; therefore, they come up with different classes of equivalence, and as the result their logics are necessarily different.
