Part 2
Whoever is to acquire a competent knowledge of medicine, ought to
be possessed of the following advantages: a natural disposition; instruction;
a favorable position for the study; early tuition; love of labor;
leisure. First of all, a natural talent is required; for, when Nature
opposes, everything else is in vain; but when Nature leads the way
to what is most excellent, instruction in the art takes place, which
the student must try to appropriate to himself by reflection, becoming
an early pupil in a place well adapted for instruction. He must also
bring to the task a love of labor and perseverance, so that the instruction
taking root may bring forth proper and abundant fruits.
