A sort of existential agnosticism. At least on the surface. More inarticulate than enigmatic. I find its protestations regarding good and bad to be more revealing of our inherent lack of prescience than an inherent lack of moral conscience. Taoism was so wanting for utility that it gave rose to Confucianism.
But definitionally, absurdism holds that meaning can be authored by the individual, for the individual. Nihilism by definition is not that. When we refuse to accept a common definition of the words we use to communicate, meaning truly is limited to the absurdist rendition of such.
Not only is reality shaped by personal perception, in some cases is it literally defined by personal perception. Usually on the quantum level, but that's a real as anything. Maybe moreso.
