You know, my boy, he said, it's impossible to love men such as they are. And yet we must. So try to do good to men by doing violence to your feelings, holding your nose, and shutting your eyes, especially shutting your eyes. Endure their villainy without anger, as much as possible; try to remember that you're a man too. For, if you're even a little above average intelligence, you'll have the propensity to judge people severely. Men are vile by nature and they'd rather love out of fear. Don't give in to such love: despise it always.
Capital punishment has probably been responsible for a good deal of human progress. The overwhelming majority of those executed were of the sort whose departures for bliss eternal improved the average intelligence and decency of the race.
I would be the last to deny that the greatest scientific pioneers belonged to an aristocracy of the spirit and were exceptionally intelligent, something that we as modest investigators will never attain, no matter how much we exert ourselves. Nevertheless … I continue to believe that there is always room for anyone with average intelligence … to utilize his energy and … any man could, if he were so inclined, be the sculptor of his own brain, and that even the least gifted may, like the poorest land that has been well-cultivated and fertilized, produce an abundant harvest..
I haven't seen much correlation between good trading and intelligence. Some outstanding traders are quite intelligent, but a few aren't. Many outstanding intelligent people are horrible traders. Average intelligence is enough. Beyond that, emotional makeup is more important.
People are what you make them. A scornful look turns into a complete fool a man of average intelligence. A contemptuous indifference turns into an enemy a woman who, well treated, might have been an angel.
The theory of democratic government is not that the will of the people is always right, but rather that normal human beings of average intelligence will, if given a chance, learn the right and best course by bitter experience.
