Religion belonged to the infancy of humanity. Now that humanity had come of age, it should be left behind.

One... gets an impression that civilization is something which was imposed on a resisting majority by a minority which understood how to obtain possession of the means to power and coercion. It is, of course, natural to assume that these difficulties are not inherent in the nature of civilization itself but are determined by the imperfections of the cultural forms which have so far been developed.

What a distressing contrast there is between the radiant intelligence of the child and the feeble mentality of the average adult.

Intelligence will be used in the service of the neurosis.
