Two Physical Treatises: On the Imposture of Healing Wounds by the Weapon Salve and On the Bleeding of Corpses

14. To this end, so that it may conserve present health and restore it when collapsed by its own efforts.
15. For us, it is not praxis practical action, but episteme knowledge/science that is proposed.
16. Nor, if the physician uses certain physical terms and differs, does he fail to act as a physician.
17. Nor do we, if we use certain terms and medical vocabulary, depart from physics.
18. For vocabulary does not constitute the distinction between arts.
19. But the reason for each, and its proper end (although the rigor of the law kath' hauto in itself/by its own nature demanded that as well).
20. We think, however, it is granted to us to use certain terms of the physicians.
21. For we know that art is related to physics.
22. Nor in a matter commonly called by such a name is it necessary to struggle for a different one.
23. Nor does the Coryphaeus leader/master of physicians, Galen, think otherwise.
24. Thus, therefore, let us begin. It is natural that what is apt to be moved toward health is healable.
25. On the contrary, therefore, it progresses when it is moved.
26. But it cannot be moved by itself.
