Yeah but thats the exact reason it doesn't hold much water for me ! We can't give them meaning or purpose or definition or anything of the sort; men much greater than you & I have tried to define 'good' & 'bad' & have utterly failed throughout recorded history & then there are those who went one step further & tried to define the very building blocks of thought & knowledge & couldn't define them !
Any definition or even any attempt to define these things entails invariably conceptualizing the definition in terms that we can relate to whether in terms of our observations (scientific or otherwise), our subconscious urges or even pure make-belief ! And this would be because we'd be using the same undefinable building blocks of thought & knowledge to define the building blocks of thoughts & knowledge; a rather cyclical & counterproductive exercise. Unless there is something that transcends these limitations in terms of both time & space, I can't imagine how anyone can define any of these things & without defining them - Theres nothing there !

Dude, the very notion of feeling and experience is personal. It is, by its very definition not supposed to have a uniform definition that will resonate with all. What I'm saying is the whole premise is wrong, just because it is impossible to have some sort of consensus, does not mean that the feelings we have or experiences we go through are meaningless.
