To say that the glass is half-full or half-empty is the tactical ploy of a con-artist trying to sell you something. The perception that it is half-full or half-empty is an illusion. Moreover it is bone-dry unless one fills it oneself. In that way one controls the content of the glass. Furthermore to think that perception is reality, and consciousness is entirely a matter of selective perception is ludicrous. That does not take into account the source of causation. If you didn’t exist, the source would anyway. And the proof is the objectivity of Universal Law. Imagining one’s reality the precise way one wants it to be to showcase an idealized image of oneself is a fool’s errand. You simply are what you are. If you want to argue the fine points of ideology that’s your prerogative, but it gets you no closer to your goal. It’s the game plan of the Children of Belial to keep humanity distracted from uniting in a common cause. As far as their game plan is concerned, it will work to perfection until the realization dawns you’ve actually gained nothing but strife. Therefore you play the hand you are dealt. Whether you win or lose the hand depends upon the cards you hold, and how you play them.
