Kaplan considers the religious attitude rather than religion as an institution. He contrasts infantilism in religion with a number of deep basic attitudes which constitute a more mature religious attitude. Infantilism in religion is as prevalent as it is in politics, art, and love. Some persistent infantilisms are discussed, such as the belief that adequate submission to an external authority assures salvation; that God, priest, and savior are essential to religion; that there must be faith in the sense of accepting propositions without any evidence; that religion is an instrument of personal wish-fulfilment. Mature religion is rare and difficult to achieve. It expresses humility, seriousness of purpose, responsibility, joy, and gratitude for the world as it is, rather than dependency, anxiety, guilt, and fantasies of complete wish-fulfilment.
