Nothing means anything or matters. Something meaning anything or mattering is an emotion, it isnt real outside your head. Negating your subjective experience is pointless(assigning meaning to meaninglessness is moronic), but that doesnt change the fact that its not real. I cant even think of any coherent way to define "meaning." I understand what it is intiutively, but I cant define it, because thats what it is, a feeling.
Nihilism is fact.
