I am older than you. Believe me, there is no other way to live on earth. Men are not open to truth or reason. They cannot be reached by a rational argument. The mind is powerless against them. Yet we have to deal with them. If we want to accomplish anything, we have to deceive them into letting us accomplish it. Or force them. They understand nothing else. We cannot expect their support for any endeavor of the intellect, for any goal of the spirit. They are nothing but vicious animals. They are greedy, self-indulgent, predatory dollar-chasers
