In the first two letters to Aenesidemus, Philaletes challenges Aenesidemus’ philosophy, going through Aenesidemus’ arguments step by step. Although they are both trying to lay the grounds for skepticism, Philaletes claims that that is the only thing that they have in common. Additionally, Reinhold, Hume, and Kant are also the victim of Philaletes critiques.
A main argument that Philaletes brings to the table is the topic of what representations are, and how we come to have them. He disagrees with critical philosophy, which follows that representations are “ideas of reason that are grounded in its nature” and instead puts forth his own view that representations are “grounded only in the nature of the imagination” (161). Where and if reason comes into Philaletes philosophy, I am not sure.
In Philaletes’ argument on representations, the principle of contradiction and the principle of consciousness are important. If I understand correctly, Philaletes claims that the principle of contradiction is the superior principle. However, I am unclear in his explanation because Reinhold contrarily believes the principle of consciousness to be higher because it includes the more important functions, like the thinking and representing of objects, while the principle of contradictions only relates to thought (164). Regardless, Philaletes agrees that the principle of consciousness may depend on the principle of contradiction (because the possibility has to be established first), but disagrees with Aenesidemus that it is determined by it (163).
The principle of consciousness cannot become necessary or a universal law because “it can…mean something different for anybody” (167). We cannot even know that others have a consciousness, or if they do, if it is the same as ours. Each of our own consciousnesses apparently is a unique constant presence in our daily lives and affects how we each perceive objects.
When we perceive an object, we are only forming what Philaletes calls a “partial representation” because the representation of the perceived object has been reproduced in our mind by the imagination, using our memory to recreate the object (169). Our representation of an object is our consciousness’ best attempt to recreate the original object that we had initially perceived through our senses.
I like Philaletes’ discussion on how the “original sensible perception [i.e. the actual chair, not the chair reproduced in your mind through the imagination] does not represent anything besides itself – and this means that in fact it does not represent anything at all” (169). What! But it makes sense that what I’m calling the original objects are not representations in themselves, and therefore do not represent themselves, or anything. They just are.
However, we never call anything something in itself, we only call things representations. When I look at a chair, I don’t think that I’m looking at the actual thing in itself. I’m perceiving what I recreate through my faculties and consciousness as a chair. Possibly because that’s how we perceive everything. We only ever ‘see’ objects as representations in our minds, thanks to our memory and imagination. Philaletes says that this is an “illusion of the imagination” (169). Unlike Reinhold, we must remember that “every perception refers to a thing-in-itself” (170). Got it.
