The last decades have witnessed an increasing interest in a global ethic, which proposes general guidelines of behavior applicable to all cultures, and amends those spiritual interpretations and educational practices that are detrimental to personal and collective wellbeing. These lecture notes are an educational resource for spiritual education, moral education, and counselling, for secondary and university levels, as well as for adult education and teacher training, all within a worldwide, multicultural framework. Drawing from the ethical and spiritual treasure of humanity, the book should help readers realize that the most idealistic and humanistic of moral codes is also the most pragmatic and profitable for each individual who lives by it.
