 As was also mentioned earlier, How Philosophy Can Become mainly emphasizes certain forms of education and an emotive type of preaching in this connection—both activities that Herder went on to theorize about at greater length elsewhere. But these are only two parts of a much broader theory and practice of moral pedagogy, or cultivation of the moral sentiments, that he developed over the course of his career, in what became one of his most central, distinctive, and consuming projects. The additional causal mechanisms that he identified and supported included the influence of morally exemplary individuals, the law, and literature (together with the other arts).
