I don’t see how even the most materialistic monist could get through life without some kind of notion of universals. I mean she looks up at night and sees points of light and calls them all stars, thus recognizing they have some general characteristics (up in the sky, point-like, bright), which she might label as universals. She might recognize that those characteristics are not strictly speaking objectively true, since “up” is relative to her; stars are not points but just a long way off; and some are brighter than others.Indeed, I made some important assumptions (which I regarded inevitable at the moment), but not the ones you have mentioned. If I am going to explain logic, it will be inevitable to use two different approaches simultaneously: observation and introspection, because it is my purpose (as a hypothetical materialistic monist) to show how my mind emerges from matter. For that, all my analysis needs to be based on current facts, and even if I need to study my memory, it will be necessary to consider some of my current acts of memory. So, I was not assuming that my concepts were built in at birth (that would be an assumption which I would never make). I was just considering certain concepts that I already have (without asking when nor how they were formed) and I was formulating a hypothesis on why I can’t think them simultaneously (because it is my personal experience that when I am thinking one of them I cannot think the other. I can think them successively, but not simultaneously; so, I don’t say that my mind stops when I try to think contradictory notions simultaneously). Now, it is not necessary to believe in “universals” to have the notion of them, and of course a materialistic monist is one of those guys who doesn’t believe in “universals”, because “matter” is always “this matter”.
I will try to continue tomorrow.
And of course, science is built on recognizing what metaphysics may or may not call “objective universals” - as Newton wrote, “In this philosophy particular propositions are inferred from the phenomena, and afterwards rendered general by induction”.
But also, we’re not conscious of most of our mind, and I think philosophers of mind have proven repeatedly, by later being proved wrong, that introspection is not a useful tool here. No amount of introspection will tell us how we recognize the face of a friend so quickly and effortlessly.
