the auttor Martin Gelabert Ballester speaks of an anthropological analysis of the act of faith by highlighting the importance of life initially began analyzing the criticism of religion because of the suspicions of the man and the components that it has , as the imperfection that is the one refers to what is not obvious , ie you never know exactly what it is , as a consequence questions come to believe " the believer that no questions are posed not have a mature and correctly believes faith," which is all clear left while believing , faith is not easy as it is to the possibility of being rejected, it is said that the most radical of all religion is faith understood as a response to God's call . Other reviews mentioned by the author are inevidence regards what is not and that creates independence (this is termed obedience) , this double feature of faith gives rise to a double critique that seems to turn the unworthy faith in the human being, then wonders who believe those who disbelieve , if faith does not begin in the area of religion , if not often believe what they see , he shows that it is necessary to believe many things without see them, St. Augustine scores that faith is a fundamental structure of human existence , a permanent dimension that makes life possible and human progress so that dispensed faith is not winning in authenticity and greatness, but losing the part of the human and integrity is the believer who accepts radically as originating source and not himself. Faith is also defined as personal trust and cultural leguaje are the natural soil that makes it possible for every human being whoever he is . In the construction of identity all phases of human beings but the believer dimension in the general sense of receiving and hosting by pure trust involved plays a more accurate critical role , ie that faith is a result of something that can not be avoided dependence of the constitutive human. The dependence of the faith , in the sense that we have here explained, is not alienating, but constitutive of personality , moreover faith favors the progress of thought , in fact the man , at birth , there enters a neutral and indeterminate but in a world already inhabited culturally and socially conditioned place , inheriting a language and ways of being , so take what comes from outside means to integrate it in my own thinking , so I find it natural to stop and be something external that authoritatively imposed. Faith is the only way that enables human encounter with the other and therefore with God if there is no faith, my "I" would be the ultimate limits of all possible experience , human faith , makes possible the coexistence and communication , then " becomes the way in which I have access to the person of another , to their deepest intimacy, its genuine reality . " which makes possible faith is the assumption that reality is not ends in oneself or in empirically verifiable , seeking truth beyond oneself and beyond appearance because it has to reach a realistic aspiration a reality , this means that knowledge of reality is different from the kind of knowledge offered by science , science provides certainty. "Faith always involves an element of uncertainty , the result of inevidence . " For all this is that I think it's very important to believe in something, always has to be a higher being in which one believes , for me to have faith is to accept the word of others , understanding and respecting it as it is the authority of the one who believes in the religious sphere think when talking about faith is God who is believed I have a place for both types of faith : divine (God) and human but to varying degrees , at least for me God I owe all faith because he has absolute knowledge and truth .
