Nel Noddings (1993), consistently arguing for introducing matters of religious and secular ethics in the classroom – "belief or unbelief" alike – insisted that education should aim for an intelligent approach to existential, metaphysical and spiritual questions and, as such, would allow us to make a connection to the spiritual realm. She refers to naturalistic ethics, which attempts to demonstrate that "the results of behaving in a certain pattern are objectively better than results obtained by other patterns of behavior" (Noddings, 1993, p. 121). Still, morality is considered a fundamentally subjective enterprise, such a stance implying that there is no foundation for moral knowledge.
