Preamble
--------

A clue to the forerunners of category theory is supplied by this recap from Saunders Mac Lane:

[[ Now the discovery of ideas as general as these is chiefly the willingness to make a brash or
speculative abstraction, in this case supported by the pleasure of purloining words from the
philosophers:  “Category” from Aristotle and Kant, “Functor” from Carnap (''Logische Syntax der
Sprache''), and “natural transformation” from then current informal parlance. ]]

— Saunders Mac Lane, ''Categories for the Working Mathematician'', 29–30.
