What can be known of subtstance, if it is different form the visible aspects or "accidental" properties of a thing?
For instance we talk of material substance, or spiritual substance, but the concept we have of material or spiritual seems to come empirically ie through experience of accidental properties. For example the fluidity of blood.
Therefore, if the substantial is not to be equated with the empirical, or accidental, then we are left with an empty concept of either "material substance" or "spiritual substance". Except, I suppose, we can know that it has certain accidental properties at certain space-times. But nothing of substance as it is itself. Thats because all we know of them comes from the accidental, which is not valid appropriate source of knowing the substantial, as it is in itself.
At least thats how it seem's to me.
I am sure someone has grappled with this before and can help. Can anything be known of substance, except it's accidens?
