We live in a time of uncertainty. But haven’t all times been uncertain times? We proceed with our everyday life being dependent on sensory perceptions that are incomplete and reveal, at best, only a fragment of reality. To be sure, we have an incomplete picture of the reality we live in since the input of data leaves huge areas out of the picture, so to speak. This makes us uncertain.
This uncertainty, if we don't think about it is, eventually, covered up by our imagination. It gives us a kind of virtual/fictional reality which can be pleasurable and comforting at times. Yes, too much uncertainty can be a problem as with too much certainty that, unbeknownst to us, is the result of the imagination filling-in the incompleteness.
Probably the worst way of dealing with uncertainty is by having too much reliance on the imagination which can lead to delusional disorders in which people cannot tell what is real from what is imagined. The dangerous side of this inevitably leads to political delusions that can be socially engineered by means of illogicality, that is, by spreading disorganized thought and communication.
Most of us are already caught in the net of political delusions from global warming to a borderless world. The power that religion once had has been taken away and handed over to the ideologues whose half baked ideas are infused with raw emotion so that they are unable to resonate with the truth.
During the late 60s the Zen that I eventually came to reject could be thought of as a halfway house for those who are in a kind of twilight zone, who would either see darkness or light. Zen when I left it had chosen to go down a path to attain darkness in the sense of resting enlightenment on the subjective and absence (non-findingness).
