Humans are not inherently bad beings, but the sharp increase in various problems in the social life of the modern world can very well make the rules of life more selfish and cruel. Only the elevating power of enlightenment can prevent this.
While every individual may not assume the role of a teacher, it is incumbent upon each one to embrace the role of an educator in matters of moral education, given its paramount importance.
Modern enlighteners, especially those illuminating ethics and personality psychology, must not only qualitatively and accessibly present the essence of a "full-fledged life" but also, by inspiring, motivate towards it.
