Scotus.....
- Agrees with Abelard that Unity is transcendental.
- Denies whatever is 'one' is an individual.
- Asserts that there is a kind of Unity that is 'less than numerical'.
- Asserts that 'common natures' have a 'degree' of reality (or being), BUT he strenuously denies that universals exist. Universality is a feature of our mental life (due to abstraction).
- Walks a line of thinking that falls between Plato and Aristotle.
- Against nominalists' claims that common natures are real.
- Against realists' claims that common natures are not universal.
- Accounts for causation in this 'degree of less than numerical'. (Experience and events provide this 'degree' of influential causation. Think about what science is now discovering about epigenetic/environmental/experiential influences.)
- Agrees with some of the Islamic polymath, Avicenna, views on common natures.
- Disagrees with Aquinas' views on common natures/species.
What constitutes an individual's essence is its 'difference' from another. We cannot grasp the lesser degree of common nature ( I would add consciousness here as well) because of our dependence on embodied physical sensation. (Again, think about epigenetics. We cannot know what influences our experiences and environment are currently having on what we will pass to our offspring because we are limited in space, time, and embodiment. We can only study what has happened in the past and the change between then and now.). Singular essences are unknowable to us, even though they ARE real. We refer to their reality indirectly by recognizing and differentiating what it is not. Example: Humans develop and recognize 'self' only in relation to that which is 'not' self.
The nominalists gleaned from Scotus what would fit their stance, and the realists gleaned from Scotus what would fit their stance. They have also done this with Peirce's work. The nominalists and realists were and are both misguided.
Moving forward from Scotus into the future of this misunderstanding.....
Ockham took the nominalist vein and ran with it, later influencing Martin Luther and Rene Descartes. Eventually becoming the protestant evangelical and scientism thinking we have today. They both still battle the realist perspective. But again, the nominalists and the realists are still both misguided. So we have all of these 'camps' of thought going round and round on this merry-go-round, and never getting off.
Physician Henry Stubbe (1632-1676) was considered to be the most noted Latin and Greek scholar of his age, as well as a great mathematician and historian. He was the first person to use the term 'semiotics'. Stubbe studied all of this in great depth, and actually tried to get the Christian community to acquire a better understanding of Islam because he too saw where the thinking split. Not that he was a proponent of Islam. He just understood what happened and was frustrated at the ignorance. Stubbe also understood that nominalism and realism were both misguided. The nominalist drive was just too popular, due to the promotion of ontological individualism. Everyone wanted respect for their own, personal, cognitive maps (their fixations of beliefs).
Even when John Locke wrote 'An Essay Concerning Human Understanding' (the second time the word 'semiotics' was used), he was leaning to the nominalist view. He broke human understanding into three categories; Physics, Pragmatism, and Semiotics. However, 'semiotics' was kind of an afterthought of the time, and never held in high enough importance due to the popularity of nominalism and the new science frenzy choosing not to include it as a relative feature.
So, here we are today, dealing with a western culture steeped in ontological individualism, evangelical Christianity, scientism, etc., (Ilya Prigogine referred to the western schizophrenia) thinking that if they just keep insisting that the Muslims have a skewed perspective that one day the 'barbarians' will wake up. Well, I've got news for everyone. We all need to wake up!
The only way to make any difference in what has happened is to try and teach the general public how human beings actually develop and how life interacts with each other. If we only recognize ourselves and our 'medium' by what it is not, then we have to realize that the only way to learn and reach a shared understanding is through dialogue with others who have a different perspective.
THIS is my reason for being here, and what motivates me to do what I do.
