Apart from the presence of instinct, thoughts, and feelings, what else characterizes human beings, if not their freedom, as the inalienable right to their own destiny? Where does this value that goes beyond animal nature live in man? Moreover, does not the consciousness of one’s own existence give the human being an awareness of his own value? It is precisely with this sense of self-worth, together with the drive for freedom, that he faces all the difficulties of life. Does not the greatness and beauty of the inner world present in the human being – who experiences the limits and overcomes them, going beyond the biological-material reality – suggest the presence of another world, that is the spiritual one?
