I am trying to understand this quote from Philo
But he asserts that the formation of the individual man, perceptible by the external senses is a composition of earthy substance, and divine spirit. For that the body was created by the Creator taking a lump of clay, and fashioning the human form out of it; but that the soul proceeds from no created thing at all, but from the Father and Ruler of all things. For when he uses the expression, “he breathed into,” etc., he means nothing else than the divine spirit proceeding form that happy and blessed nature, sent to take up its habitation here on earth, for the advantage of our race, in order that, even if man is mortal according to that portion of him which is visible, he may at all events be immortal according to that portion which is invisible; and for this reason, one may properly say that man is on the boundaries of a better and an immortal nature, partaking of each as far as it is necessary for him; and that he was born at the same time, both mortal and the immortal. Mortal as to his body, but immortal as to his intellect.
