Rigor

 Logic is the new magical thinking.
Our ancestors died when they have decided that certain things mean the end of it, its death. When you are sad to the core and kills the self for it, it is the end of it. When sickness hit you, the plague is unstoppable, it is the end of it. When war or raging higher up men, powers you, it is the end of it. Until a logic man comes up and tells all of it, this taxonomical life.

You are not sad, you have depression, it is just a fact and not the end of it. You are not sick to die, you have a sickness, it is just fact and not the end of it. You are not a soldier, it is just fact, and political boundaries can be changed by rigorous action, it is not the end of it. Logic is optimism at the not dying. It is just how we kept on living. It is how we increase the average age of living.
