Cooper says that a formalist, with only formal constraints on his logic
(such as consistensy) is at the mercy of the formalism itself. Such a
formalism is allways a special case, but Cooper warns of the danger that
classical logic is not recognized as such. He calls for a relativistic
evolutionary logic where classical logic only would be justified for certain
special classes of problems. An evolutionary metatheory of logic would
recognize which those problems are.

If this is all that Cooper is talking about, I probably wouldn't have any
objection to it--but Lennart Nilsson seemed to be making much stronger
claims about the contingency of logic itself based on his interpretation of
Cooper.
