Our former discussion was about the meaning of the historical or social evolution of man in the past. We-examined the question whether the processes which man and his society have undergone may be called evolution or at least progress, or whether there is a third alternative explanation that in some aspects of social life considerable progress has been made, while in other aspects there has been no progress or evolution. Or we may, at least, say that if there has been progress it has been very slow and out of harmony with the rate of progress in technical matters and evolution of social structure. The dimension in which man has not been able to make proportionate advance is the human dimension of social life.

If we liken man's social life to an individual human being, technical progress and social development may be thought of as the body of society, while the human aspect of social life is the ethos of the individual. We may conclude, therefore, that humanity has physically overgrown, while its spirit and human ethos have made very little headway. The divergence between various views concerning the future is rooted in this matter.
