I was always taught that, in this context, "philosophy" means philosophia naturalis that's to say, science of the natural world, as then pertaining.
On the subject of ghosts, there were many ideas in the Greek science that Renaissance science grew on (as with maggots breeding in a dead dog...).
Plato says: “... if the soul is polluted and impure when it leaves the body, having always been associated with it and served it, bewitched by physical desires and pleasures to the point at which nothing seems to exist for it but the physical, which one can touch and see or eat and drink or make use of for sexual enjoyment… this bodily element is heavy, ponderous, earthly, and visible. Through it, such a soul has become heavy and is dragged back to the visible region in fear of the unseen and of Hades. It wanders, we are told, around graves and monuments, where shadowy phantoms, images that such souls produce, have been seen, souls that have not been freed and purified but share in the visible, and are therefore seen.”
