Lactantius

“ But because they did not comprehend the nature of the soul, which is so subtle that it escapes the eyes of the human mind, they said that it perishes. What of Aristoxenus, who denied that there is any soul at all, even while it lives in the body? But as on the lyre harmonious sound, and the strain which musicians call harmony, is produced by the tightening of the strings, so he thought that the power of perception existed in bodies from the joining together of the vitals, and from the vigour of the limbs; than which nothing can be said more senseless. ”

“ As long as the soul is bound by fetters to the body, perceiving corruptible sufferings, it yields to mortal pains; but when, after the wasting of the body, it has found a very swift dissolution of mortality, it is altogether borne into the air, never growing old, and it remains always uninjured ”

“ But this has happened to many philosophers, that they did not believe in the existence of any object which is not apparent to the eyes; whereas the sight of the mind ought to be much clearer than that of the body, for perceiving those things the force and nature of which are rather felt than seen. ”
