We think reality into being, using the stuff of existence (which, of itself, has no meaning).
This is now obvious in the sense that facts and evidence clearly don't matter - only the power to impose ideology... which is the power to impose interpretations.
Thus reality depends on thinking. For a Christian; free will or human agency is a truth - so our thinking is chosen; for Modern Man that choice must be conscious.
If instead we choose to believe that reality is unchosen, that reality is that which is forced upon us; then we will believe that The System is reality.
Therefore, the mass majority who are passive, unchosen, unconscious; who receive reality - do not think, but are thought-by The System.
All the time.
Their thinking is a Product of ideology interpretation, applied to controlled perceptions/ manipulated emotions and memories of perceptions and emotions.
It is that first decision not to think From oneself that leads inexorably to being-thought by The System.
And The System is evil.
