I have a very existentialist and zen absurdist philosophy most can't understand.
Basically "existence preceeds essence".
I don't worry about metaphysical things mostly. I get a sense of awe from nature and aesthetics in a direct way without "spiritual overlords". The Japanese word "Yugen" most aligns to my thinking.
About ethics...People can think they have a framework of ethics but randomness and circumstances beat ethics every time. All that matters is what you do, not what you think you'd do.
Thanks for the question.
