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.

Every person, every place and every action is qualified by this association with the unconditional; it penetrates every moment of daily life and sanctifies it: "The Universe is God's sanctuary. Every work day is a day of the Lord, every supper is a Lord's supper, every work a fulfillment of the divine task, every joy a joy in God. In all preliminary concerns, ultimate concern is present, consecrating them."

Sometimes I think it is my mission to bring faith to the faithless, and doubt to the faithful.

But freedom is the possibility of a total and centered act of the personality, an act in which all the drives and influences which constitute the destiny of man are brought into the centered unity of a decision.

The citizens of a city are not guilty of the crimes committed in their city; but they are guilty as participants in the destiny of [humanity] as a whole and in the destiny of their city in particular; for their acts in which freedom was united with destiny have contributed to the destiny in which they participate. They are guilty, not of committing the crimes of which their group is accused, but of contributing to the destiny in which these crimes happened.

The fatal pedagogical error is to throw answers like stones at the heads of those who have not yet asked the questions.

Doubt is the necessary tool of knowledge.
