>From Aristotle's "Categories", the first book of The Organon (trans. Harold P. Cook):
"When genera are co-ordinate and different, differentiae will differ in kind. Take the genera, animal and knowledge. 'Footed', 'two-footed', 'winged', 'aquatic' are among the differentiae of animal. But none will be found to distinguish a particular species of knowledge. No species of knowledge will differ from another in being 'two-footed'."
