"The reasonable man adapts himself to the world. The unreasonable man persists in trying to adapt the world to himself. All progress therefore depends on the unreasonable man." (George Bernard SHAW) So sometimes, our certainties, our freedoms in our life choices, accentuate and considerably aggravate the consequences of our actions. It's the same for our free will, our best alibi in the face of the disasters that dot our lives to the fantasy of our decisions, this "true false friend" sometimes cumbersome or even disabling, this invention of MEN intended to comfort us in our choices, become by force of events, the best friend of our Ego.
