“ Yet methinks it is not unreasonable to propose, that words standing 
for things which are known and distinguished by their outward shapes should 
be expressed by little draughts and prints made of them. . . . Naturalists, 
that treat of plants and animals, have found the benefit of this way : and he 
that has had occasion to consult them will have reason to confess that he 
has a clearer idea of apium or ibex, from a little print of that herb or beast 
than he could have from a long definition of the names of either of them.” — 
John Locke ( ob . 1704 ).
