James stop. Your debate with Imp is completely devoid of the potential for progress. Not only are you speaking completely different languages, but you are speaking those different languages from completely different spheres of thought. Consider the citation of Hume in this debate:
Humean epistemological thought, when disentangled reveals itself to be a kind of solipsism, or even nihilism. Hume believed that there is no way for the mind to get beyond it’s sensory ‘impressions’ and the ‘ideas’ that they produce, and so, he believed that there is no rational reason to believe that an external world exists apart from our subjective experience of it.
How does one disprove such a position? How does one get beyond oneself and ones experience of the world so as to prove that the world exists? It is impossible to disprove a negative, and so the very merit of the debate is dubious. Why do we feel compelled to pay any mind to such positions and, in paying them mind, validate them? Let them sit and eat at their empty banquet of solipsism and their nihilism; we shall feast upon knowledge and enjoy the fruits of knowledge. No mean skepticism launched us into space, exploded the power of the sun, or spun a web of thought around this celestial sphere.
The world and we are one; the ocean that surrounds us splits into streams and flow through us, and we flow into that self same ocean. Yes, yes, this all may be a dream, but does this reveal philosophy in oneself or betray a penchant for idle speculation and petty disputing?
X happens and then Y happens… every time… and from that you conclude that X is a necessary condition of Y?
Let’s replace X with “throwing a rock in the air” and Y with “gravity pulls the rock towards the ground” and see how that holds up…
it becomes… “Thorwing a rock in the air is a necessary condition for gravity to pull the rock towards the ground”
is it me or does that seem a bit off?
so far as I know gravity works independently of us throwing rocks… they are constantly pulled towards the ground whether we throw them or not… so it seems your reasoning is flawed somehow…
IF X then Y (is what we observe)
If Y then X (is what you conclude)
this is not valid…
or perhaps I have misunderstood you?
furthermore… from your examples of physicle reality effecting the mind you seem to conclude that ONLY physicle things can effect the mind… for which you have no basis… all you have is thaty physicle reality can effect the mind… not exclude other things from effecting it as well.
