The book includes a collection of articles resulting from research carried out by teachers of the Department of Humanities and whose thematic center is the relationship between people and happiness. Each chapter provides answers from a specific disciplinary field, through a qualitative methodology, the anthropological and ethical problem of achievement of happiness or personal human fulfillment. From education and ethics, the transition from some informative humanities to other performative ones is proposed, which integrate moral formation and values that advocate empathy and solidarity as a human path to happiness. From the anthropological keys of Leonardo Polo, the person can give meaning to their presence in the world, beyond the satisfaction of happiness itself, since human beings has a personal sense capable of manifesting themselves in the hopeful task. Likewise, from the personalistic anthropology, happiness is studied as a life project, moving from the conflict towards spirituality and proposing chose political educational transformations. In the field of historical sciences, the use of the concepts of person and happiness in the Magisterium of John xxiii underlines the perspectives suggested by the Pope and collected by successive pontiffs. From the law, the relationship is analyzed between justice and happiness, applied to the so-called “right to die with dignity”; and from the bioethics, reflections on procreation and happiness are raised based on the current debate on surrogacy.
