The current dissertation under title The human being, a being of relationship: the Integral Ecology as reintegration and reconciliation path, as the objective to go into the teological antropology having as most inspiration the Laudato Si Encyclical. In the encyclical Pope Francis presents us the big impacts of socio-environmental crisis we are through and the alternatives to face it. This crisis is also a humanity crisis, seen from of the modernity with showing up of tecnocratical paradigm, there was a deep change in the human being comprehension that influenced directly on the way it is stablished its relationships. When self declaring lord, dominator and explorer of nature using technical apparatus, the human being goes litle by litle distancing of its own identity and completeness and its relationship become marked by superficiality, individualism and by lack of gratuity. When we bring the concecpt of Integral Ecology we want to evoke it as new paradigm to replace the technocratical. A paradigm that effective a rehumanization process where human being overcome all and any dualism and self reinteger as person. Besides, we are sure human being, is by nature, a being of relationship, urge its relationship restoration with God, with its pairs and with nature such as reconcialiation movement. Rebuild the human being today is fundamental for us to think future existence of humanity on earth.
