The introspective approach, more often reserved for practical psychology to gain self-knowledge or knowledge of the human spirit in general, finds in this book by José Musangana a field of application for the acquisition of Ubuntu from nature, as an adjuvant that should enable us to ensure reciprocity towards this generosity of nature. Preserving nature today, for the fulfillment of human life, should be done by integrating adherence to certain values and respect for ecosystems and nature's potential. The approach developed in this book by José Musangana is in line with this logic.
