it's true that he's not what would be the "father of nihilism" per se, but he is known today as one of the contributors of that "side" of existence. Yet he warned against it, much like Karl Marx said "I would not be a communist" after writing his book, lol.
Anyway... Count you sound a lot like myself in some respects. The insomnia and the at times dissociated ramblings which is probably a direct effect of the insomnia. However you really should question your views/beliefs/morals whatever you want to call it. There are no truths in this world. There are no laws. Socrates said something along the lines of "Most people believe they know everything. I am smarter because I know that I know nothing," Though I'm just pulling from memory and obviously it was from Plato's account of Socrates not a direct quote or writing of his... Though at times I wonder if Socrates was real.
Anyway I hope you can find some relief for your insomnia... mine at times is hardly there and at other points kills me. I think the longest I have ever gone without sleep and without any drugs was 5 days/nights. For me I discovered I had ADHD when I turned 30 this January and even though a side effect of the stimulant medication I take is lack of sleep it actually helped with my insomnia.
The longest I've gone is 4 days/nights (and then I collapsed).
I posted these stories as Night #, to tell of my nocturnal nature, I do get some sleep when I'm tired and passing out, lol.
I had an ex-gf who said I channel the energy of the moonlight,
(and when I couldn't sleep, she couldn't sleep.)
Ahem.. lately, I've been sleeping at 4 am, which is past the witching hour (3 am). I tire myself out by running the treadmill and using the gym in the garage.
I think I might have ADHD though, but it's not always there.. sometimes I can focus intensely, other times I'm really scattered. I blame it on the Gemini influence in my birth chart, lol, it's a very bipolar volatile sign. Yet my ability to paint pictures with words, comes from having Mercury and Mars both in Gemini, it's like a gift and a curse.
I'll look more into philosophy, I'm taking a class on it actually.
my own philosophy is astrology and occult based, also from personal observations, which might or might not align with what the ancient heroes taught. People say life is a constant struggle between good and evil, and I do, suffer that conflict.
I think nocturnal/insomnia is actually a blessing in disguise, it's a call for us to embrace self-discovery. As far as if Socrates was real or not, is kind of like some people say Shakespeare was not real, but only a pen name for someone now unknown.
Yet the name is immortalized, and through the names, we get certain feelings and memories evoked from us.. just like Achilles, Socrates, or maybe even.. CountFury. ;)
