_LIMITS OF THE HUMAN MIND_
Someone asked Newton one day why he walked when he wanted to, and how
his arm and his hand moved at his will. He answered manfully that he had
no idea. "But at least," his interlocutor said to him, "you who
understand so well the gravitation of the planets will tell me why they
turn in one direction rather than in another!" And he again confessed
that he had no idea.
Those who taught that the ocean was salt for fear that it might become
putrid, and that the tides were made to bring our ships into port (The
Abbe Pluche in "The Spectacle of Nature"), were somewhat ashamed when
the reply was made to them that the Mediterranean has ports and no ebb.
Musschenbroeck himself fell into this inadvertence.
Has anyone ever been able to say precisely how a log is changed on the
hearth into burning carbon, and by what mechanism lime is kindled by
fresh water?
Is the first principle of the movement of the heart in animals properly

seek the limits of your mind. They are at the end of your nose.
_LOCAL CRIMES_
Traverse the whole earth, you will find that theft, murder, adultery,
calumny are regarded as crimes which society condemns and curbs; but
should what is approved in England, and condemned in Italy, be punished
in Italy as an outrage against the whole of humanity? That is what I
call a local crime. Does not that which is criminal only in the
enclosure of some mountains, or between two rivers, demand of judges
more indulgence than those outrages which are held in horror in all
countries? Should not the judge say to himself: "I should not dare
punish at Ragusa what I punish at Loretto"? S
