Leonardo da Bitchy

(that title was fun)

Here’s Leonardo lamenting stupid people:
It seems to me that men of coarse and clumsy habits and of small
knowledge do not deserve such fine instruments nor so great a
variety of natural mechanism as men of speculation and of great
knowledge; but merely a sack in which their food may be stowed and
whence it may issue, since they cannot be judged to be any thing
else than vehicles for food; for it seems to me they have nothing
about them of the human species but the voice and the figure, and
for all the rest are much below beasts.

and just the other day he said this about studying things you don’t like:
Just as eating against one's will is injurious to health, so study
without a liking for it spoils the memory, and it retains nothing it
takes in.
