This book is dedicated to analyzing and comparing the most important philosophical ethical traditions in order to see what values and principles they share in common, as well as the possibilities of reaching a agreement on universal ethical principles. We will also seek to harmonize ethical traditions based on the good and happiness with ethical traditions based on duty and moral norms, as well as show the current need to reach a global consensus on a broad core values through an interdisciplinary, intercultural and interreligious dialogue that will serve as a basis for an ethical education that promotes the achievement of the desired goal of world peace.
