Our search for such [moral] principles can start with . . . the unconditional imperative to acknowledge every person as a person. If we ask for the contents given by this absolute, we find, first, something negative-the command not to treat a person as a thing. This seems little, but it is much. It is the core of the principle of justice.
Paul TillichIn those who rest on their unshakable faith, pharisaism and fanaticism are the unmistakable symptoms of doubt which has been repressed. Doubt is not overcome by repression but by courage. Courage does not deny that there is doubt, but it takes the doubt into itself as an expression of its own finitude and affirms the content of an ultimate concern. Courage does not need the safety of an unquestionable conviction. It includes the risk without which no creative life is possible.
Paul Tillich[A] process was going on in which people were transformed into things, into pieces of reality which pure science can calculate and technical science can control. … [T]he safety which is guaranteed by well-functioning mechanisms for the technical control of nature, by the refined psychological control of the person, by the rapidly increasing organizational control of society – this safety is bought at a high price: man, for whom all this was invented as a means, becomes a means himself in the service of means.
