Contemporary man, therefore, fears that by the use of the means invented by this type of society, individuals and the environment, communities, societies and nations can fall victim to the abuse of power by other individuals, environments and societies. The history of our century offers many examples of this. In spite of all the declarations on the rights of man in his integral dimension, that is to say in his bodily and spiritual existence, we cannot say that these examples belong only to the past.
Man rightly fears falling victim to an oppression that will deprive him of his interior freedom, of the possibility of expressing the truth of which he is convinced, of the faith that he professes, of the ability to obey the voice of conscience that tells him the right path to follow. The technical means at the disposal of modern society conceal within themselves not only the possibility of self-destruction through military conflict, but also the possibility of a "peaceful" subjugation of individuals, of environments, of entire societies and of nations, that for one reason or another might prove inconvenient for those who possess the necessary means and are ready to use them without scruple. An instance is the continued existence of torture, systematically used by authority as a means of domination and political oppression and practiced by subordinates with impunity.
