Author's Notes: This story starts with section 6. This is not a mistake. I have my own subtle reasoning. So, just read, and enjoy.
Isaac AsimovOld men tend to forget what thought was like in their youth; they forget the quickness of the mental jump, the daring of the youthful intuition, the agility of the fresh insight. They become accustomed to the more plodding varieties of reason, and because this is more than made up by the accumulation of experience, old men think themselves wiser than the young.
Isaac AsimovWhen, however, the lay public rallies round an idea that is denounced by distinguished but elderly scientists and supports that idea with great fervor and emotion - the distinguished but elderly scientists are then, after all, probably right.
Isaac AsimovTo me it seems to be important to believe people to be good even if they tend to be bad, because your own joy and happiness in life is increased that way, and the pleasures of the belief outweigh the occasional disappointments. To be a cynic about people works just the other way around and makes you incapable about enjoying the good things.
