Our knowledge is a receding mirage in an expanding desert of ignorance.

In progressive societies the concentration[of wealth] may reach a point where the strength of number in the many poor rivals the strength of ability in the few rich; then the unstable equilibrium generates a critical situation, which history has diversely met by legislation redistributing wealth or by revolution distributing poverty.

Progress is the domination of chaos by mind and purpose, of matter by form and will. It need not be continuous to be real.

Historically the belief in heaven and the belief in utopia are like compensatory buckets in a well: when one goes down the other comes up. When the classic religions decayed, communistic agitation rose in Athens (430 B.C.), and revolution began in Rome (133 B.C.); when these movements failed, resurrection faiths succeeded, culminating in Christianity; when, in our eighteenth century, Christian belief weakened, communism reappeared. In this perspective the future of religion is secure.

Even when repressed, inequality grows; only the man who is below the average in economic ability desires equality; those who are conscious of superior ability desire freedom, and in the end superior ability has its way.
