I never claimed to be a genius.
I never denied it either but I think they exist and I believe they have existed in the past. One such example that is hard to doubt is Nietzsche. How about I draw on what he said in one of his books, say “Twilight of the Idols”?
You are asking me to show you that we already found something that doesn’t need a hypothetical about a trillion years into the future. This “something” related to a doubt of Platonic forms that philosophers have already raised, such as Nietzsche. I have already shown you doubts from my own thoughts that you’ve not even addressed, but you’re still asking to be shown, so maybe he will help? It’s a real struggle to extract any sense from you about both your own explanations or even your requirements for proof, so all I can do is add to the pile of what I’ve already offered with the following.
Right at the beginning of the fore-mentioned book, in “The Problem of Socrates” Nietzsche writes that he “recognized Socrates and Plato as symptoms of decay” standing “in the same negative relation to life”: “It was he who handed himself the poison cup”. This continues to be advanced shortly later in “The Four Great Errors” that begins with “There is no more dangerous error than that of mistaking the consequence for the cause”. An example of this error is mentioned just before in “‘Reason’ in Philosophy”: “The ‘apparent’ world is the only one: the ‘real’ world has only been lyingly added…” as he draws from Heraclitus. Plato inverts this, mistaking the consequence of seeing similar “forms” caused by “the apparent” as “Platonic forms” that cause “the apparent”. In true Nietzschean style, he is merely diagnosing sickness and decadence in the kind of intellect that demotes the real to mere illusion that is “in fact” caused by a “more real reality” that lurks beneath - which they aspire to reach in just the same way as the Christian does. Back to “The Problem of Socrates”: “To have to combat one’s instincts - that is the formula for décadence”.
He goes on to sum up the mechanism by which the “monstrum in fronte, monstrum in animo” turn away from life in “How the ‘Real World’ at last Became a Myth”.
This is just the beginning of one book by one more recent philosopher - I only stick to Nietzsche because it’s him that I know best. There are plenty of others to pick from, just pick one and go from there. I may attack your ideas, but I am not your enemy, I am trying to help.
I’m not vitriolic or hating, though I am uncompromising in the expression of my frustration with characters such as yourself who present themselves as having easy answers like some kind of prophet or saviour whilst having little to no real substance to back it up - as elucidated by the kind of rigorous deconstruction that I admittedly take joy in providing. It’s hard not to develop an ego when you have put a lot of time and energy into getting particularly good at doing this, but I genuinely try to hold it back as much as I can - my apologies if it slips through.
