A belief that will make one person happy will make another miserable. Look at any religious society and you will find that the individuals cannot agree in belief. So those who cannot agree are slaves to those whose authority they admit as their rulers. The cause of man's misery and trouble lies in our false reasoning. It always has and it always will be so till man is convinced that his happiness depends on Wisdom, and his misery on belief.
People never seem to have thought that they are responsible for their belief.
To analyze their beliefs is to know themselves, which is the greatest study of man. All theories for the happiness of man contain more misery than happiness, either directly or indirectly. Our opinions are the foundation of our misery, while our happiness is in the knowledge that follows solving the problem of error. To illustrate, when solving a problem you have an opinion, and are in trouble about it. But when the answer comes the happiness accompanies it.
