This reminds me of a quote in Sowa's book Knowledge Representation, 
introducing the chapter on Ontology:

"... We must philosophize, said the great naturalist Aristotle -- if only 
to avoid philosophizing. ..."  [and more] (Quoted from Charles Sanders Peirce.)

I took this, in part, to be a caution against trying to regard logic, etc., 
as a mere formal abstraction -- that is must in some way be grounded in or 
related to the things that affect us as people.
