Since the previous is true, that knowledge leads to the understanding that 'anything is possible'. Not all things are 'probable, or plausible', that they are 'true', or will happen, but just about anything is 'possible'. In fact, if the stars were to start moving in funny patterns you would have to accept it, you could not deny it. There is a lot of debate, probably arising from the way our 'civilization' is structured, concerning many different things. Some of these debates are 'crucial' to increase 'happiness' and some are not.
Some debates lead to miscommunication, others to 'new angles' on old circumstances.
Some fights, others winners. With all the possibilities, we are each left with personal choices. What to debate, why we should and where this leads us. I am going to go the social 'norm' route and express some of what I believe to be important 'debates', based on my experience. The issue of 'income tax' is a major one.
