Life does not exist in a vacuum. Every living organism is the product of complex chemical and biological mechanisms that we are just beginning to truly understand.
Minds, likewise, do not exist in a vacuum. Our days do not unfold in a vacuum: they are not sequences of events disconnected and disengaged from each other.
Yet we live, for the most part, like our actions do not connect to reality. We pretend that the events that unfold around us are something that we have no control over.
We pretend that we have no history and no past, because it lets us shape our future according to our whims and our fantasies.
