Each individual arises not from the exact same set of causes repeating itself, because, perhaps like a flowing river, causative factors can never remain static. The human gene pool at any given time, and in different eras, has been definably different than it is now. Add in environmental and epigenetic factors that will alter gene transcription, and you can never reproduce that situation that lead specifically to the reproductive event that gave rise to you.
How do we know ourselves? How do we know who we are?
I am a unique snowflake. Indeed, but there was a set of factors that let you come into existence, and they have persisted and will persist after the event that is you transforms beyond its currently recognizable state. Yet we do perceive ourselves to exist, yes?
We mistakenly localize the self around a center that in and of itself doesn’t exist. If you visualize a vortex, like a chakra, a whirling collection of energy, having a definable form and observable behavior, can you find it’s center? Is there an object there?
The center is the absence of wind. The absence of energy. We perceive absences because we primarily perceive things as being material, but in fact, all the matter we experience has the same set of principles behind its own origination. The same thing that lets us perceive matter, as existing, is the reason it exists.
Its center could be anywhere away from that collection of energy? Its center is the omnipresent sea. If you look at a whirlpool in the ocean, you would have to trace every exchange of energy in that ocean, every surrounding tide, and every tide linking to that, and would you find one cause? One tide that started that whirlpool?
The sea? The sea is being, but we have events. We have objects in this field of universal being.
But it is the being of the sea that allows the events? Yes, allows rather than forces, permission and not mandate.
