Igitur in hac re Pythius errasse videtur, quod non animadvertit ex duabus rebus singulas artes esse compositas, ex opere et eius ratiocinatione, ex his autem unum proprium esse eorum qui singulis rebus sunt exercitati, id est operis effectus, alterum commune cum omnibus doctis, id est rationem, uti medicis et musicis et de venarum rythmo ad pedem motus, ut si vulnus mederi aut aegrum eripere de periculo oportuerit, non accedet musicus, sed id opus proprium erit medici;
Therefore in this matter Pythius seems to have erred because he failed to perceive that the several arts are composed of two things'craftsmanship and the theory of it. Of these the one, craftsmanship, is proper to those who are trained in the several arts, namely, the execution of the work; the other, namely, theory, is shared with educated persons. Physician and musician alike deal with the rhythm of the pulse and the movement of the feet. For example, if a man has to heal a wound or to rescue a sick man out of danger, it is not the musician who will come, but it will be the special work of a physician.
