I should have pre faced my post was I don't agree with your OP.
What we do is soak up signal from our surroundings and then evolve whats been soakted in. We begin in the womb by soaking in our mothers' emotions and thoughts and actions, the father aslo has an input on the baby. So when the baby is born he/she is a collection of what they soaked up.
As in you do not agree that there is no such a thing as a Freethinker?
