If a person didn’t have any knowledge of Metaphysics, and was a scientist, and if you asked him what is universally common to all matter, what do you think he would answer. Would it perhaps be 3D dimension, weight, size, shape, density, color, occupies space, temperature, movement, things common to all physical matter. His observation is in the realm of the physical, do you think he would be in the same place that empirical scientists are today? And is empiricism totally wrong? I just find they would be very limited by not transcending to the spiritual level, not that they were totally, or even wrong in their discoveries in the place they find themselves. Some think that atoms are the physical, material elements that is the common material element to all matter. Do you think they are totally wrong. To deal with the nature of a thing, isn’t that part of Metaphysics, abstract, the intelligible species. Universals on the material level, are material, Universals on the intelligible level are Metaphysical. This is what you are using. Could you design a computer with this knowledge alone? I am using the common meaning of universals, not the Metaphysical.I’m not sure exactly what you mean or trying to convey by the phrase “material universals”, but I believe this phrase would be foreign to the scholastics and I don’t believe I’ve come across it in Aquinas’ works. In Aquinas’ doctrine, a 'material universal" would in a sense be a contradiction. For matter is the principle of individuation and whatever is composed out of matter is some particular material thing such as a particular atom, rock, plant, or horse.
A universal concept comes not from the matter of some thing but from its form. It is the form which places some thing into a class of things, for example lions, and through which a thing has some specific nature. The form determines the matter. The form is also a principle of knowledge. Matter in and of itself, prime matter, is unintelligible. The intellect abstracts the form of some thing from all the material individuating characteristics and thus we can understand the essence and substance of a thing. This abstraction gives us the idea of the essences and natures of things such as humanity, horseness, etc. This is the universal which is the object of scientific knowledge. The essence of a material substance considered as a universal includes matter, however, not individual matter such as these bones and this flesh, but common matter as Aquinas calls it. For man cannot be conceived without flesh and bones but the universal “humanity” does not include individual flesh and bones such as the flesh and bones of Socrates, but flesh and bones in general. The universal concept known by the intellect is immaterial even though it may include common matter because you can’t imagine it, if you tried to imagine it you would be imagining some particular thing such as a particular man, it is something known only by the intellect. The universal cannot be imagined.
You say that a universal does not come from the matter of a thing…are you not thinking about the intelligent species as regards matter? I am speaking of the sensible species.Are you saying that there is nothing physical that is common to all physical things?
