Ne supra crepidam sutor iudicaret. Let the cobbler
stick to his last. Apelles 4c Quoted in Pliny
Naturalis Historia, 35.36.85. A cobbler who had criticized Apelles'
way of rendering a sandal in one of his paintings, proceeded
to criticize the rest of the painting as well. The expression
thesoul of a prince enterand informthebody of a cobbler, as
soon as deserted by his own soul, everyone sees he
would be the same person with the prince, accountable
only for the prince's actions; but who would say it
was the same man? John Locke Essay Concerning Human Understanding, bk.2, pt.27, section15.
