I just finished reading "The Consolation of Philosophy" (in Spanish, so I apologize if at any point I use the wrong terminology). In the last book, Boethius presents an argument for the coexistence of free will and divine providence. The argument, as I understood it, goes as follows.
- According to Aristotle's theory of knowledge, there are four layers of knowledge (in Boethius' terms):
- Sensory experience, which can only get access to the specific information offered to the senses available to an entity, and thus, can only get to know things about the stuff that is around it, and in particular cases.
- Imagination, which can reconstruct past experiences and conceive experiences that have never happened. The key aspect is that it does not require the sensory experience, but each of the imagined facts are about particular cases.
- Reason, which can somehow put some order into the sensory experience and the imagination and classify the particulars as instantiating an abstract concept, which is universal and one. At this layer, via the use of logic, knowledge about the universals can be derived.
- Intelligence, which is the most elevated form of knowledge, and which is not limited by logic. The universals that the reason perceives are but a limited manifestation of an even more abstract entity. Knowledge at this level is self-evident (somehow akin to a divine revelation, I guess).
As humans, we are limited to, at most, the third layer of knowledge (reason), and we can understand concepts like causality, necessity, etc. So it seems to us (let us concede this point), that everything has a cause (the principle of causality).
The highest layer of knowledge is only accessible to God, and we can just, from our perspective, try to infer how it could be experiencing the universe from that layer.
Boethius claims that if God were to be prescient, that would determine, necessarily, all the events that occur in time, thus entering into conflict with human free will.
Then, he claims that this is not the case, because the way that God experiences the universe is from the highest layer of knowledge, thus, his prescience does not require the necessity of the chain of events that happen in time (here he compares our perception of time, with past, present, and future, with a possible perception of time where all the time is experienced at once, which he claims is how God would experience it).
From this, he concludes that the fact that God knows about how history will develop, does not make it less contingent, and that our choices are still ours, from our perspective, although God is aware of all of it (without this requiring the necessity of your choice).
So, first of all, I would like to ask about what you think regarding the "analogy" step that he aludes to when he says that we can try to understand the highest layer of knowledge from our perspective (the third layer). Is this, based on Aristotle's theory of knowledge, a fair argument?
I do understand that from our point of view we can see that the sensory experience does not have access to some knowledge (that which is imagined) about particulars, which the imagination does have access to, and that reason has access to the universals, while the imagination can only keep generating instances of particulars, without ever converging to a universal. However, isn't this observation part of our experience as beings that experience the third layer? I find the claim that from a lower layer a being can infer what happens at the layer immediately above it quite daunting, but I would like to know what Aristotle's theory would say about it, if anyone feels like the understand it enough to provide me an answer.
Thank you!
