Montessori Quote
If the different individuals have to live harmoniously in one society, with a common aim there must be a set of rules which we call morality. Therefore, we can consider morality as a form of adaptation to a common life for the achievement of a common aim. Morality, which is usually considered as an abstraction, we wish to consider as a technique which allows us to live together harmoniously.
Maria Montessori, Citizen of the World, p. 26
