Everything in nature runs toward one thing: procreation.
Every living system exists to reproduce itself.
That is why in humans and other mammals, orgasm exists as a reward for mating.
In animals, the cycle is simple.
The female goes into season.
The males circle, fight, and one mates.
In humans, it is not so raw.
Because humans have language.
With language comes meaning.
With meaning comes choice.
With choice comes agency.
With agency comes responsibility.
With responsibility comes authorship.
