The opposite of existentialism

Existentialism says, according to Alexander Bard, we are what we think, what we say and how we act, we identify with all those things and it is not the other way round, nature does not force us to act in any particular way.

I believe just the opposite. Nature in fact causes us to behave in a certain way and our minds are part of nature. Does this place essence before existence? If nature is defined as essence, yes.

Then there is the matter of the Activation Within, or Tirips, which is activating life to evolve eventually to ascending levels of Godhood. This too is part of nature. We have freedom or free will within the determined paths of life and evolution, just a little freer than a boulder rolling down a mountain. We evolve toward more efficient forms, more complex forms, with starts and stops and backward goings along the way, heading up the mountain toward Godhood at the zenith of evolution.
