[Most of] Our minds are our greatest defense, yet our weakest foundation.
It protects us by any means necessary for survival. "By any means necessary" paves the way for decisions to come.
A defense system, constantly under attack, will only evolve it's military. It's intel is based on solid war evidence - Things that can damage the self, and things that can destroy others.
A defense system, not needed and constantly protected, will only evolve a delusion. A world of no requirements - Too easy to accept, and incapable of evolving.
We cannot be ignorant towards the world around us. We cannot act on the assumption of a singular path. We cannot be a solid block - inyielding. We cannot be glue - accepting.
We must adjust to becoming the porous, yet solid, sponge that is capable of resisting and absorbing and rung out if necessary but maintaining a sliver of the past.
We must learn to evolve and evolve as a unit.
