I don't understand why, if you are trying to keep your mind from any kind of limiting conceptual framework, you conclude so concretely that the body is for reproduction...
Obviously that is not correct. What about when I was 8? Did my body have no reason for being?
"Ah, those endless forests, and their horror-haunted gloom! For what eternities have I wandered through them, a timid, hunted creature, starting at the least sound, frightened of my own shadow, keyed-up, ever alert and vigilant, ready on the instant to dash away in mad flight for my life. For I was the prey of all manner of fierce life that dwelt in the forest, and it was in ecstasies of fear that I fled before the hunting monsters."
Jack london, "Before Adam"
