Faith as ultimate concern is an act of the total personality. It happens in the center of the personal life and includes all its elements. Faith is the most centered act of the human mind. It is not a movement of a special section or a special function of man's total being. They all are united in the act of faith. But faith is not the sum total of their impacts. It transcends every special impact as well as the totality of them and it has itself a decisive impact on each of them.

Dialectics is the way of seeking for truth by talking with others from different points of view, through "Yes" and "No," until a "Yes" has been reached which is hardened in the fire of many "No's" and which unites the elements of truth promoted in the discussion. It is most unfortunate that in recent years the name "dialectical theology" has been applied to a theology that is strongly opposed to any kind of dialectics and mediation and that constantly repeats the "Yes" to its own and the "No" to any other position. This has made it difficult to use the term "dialectical" to denote theological movements of a really dialectical, that is a mediating, character; and it has resulted in the cheap and clumsy way of dividing all theologians into naturalists and supernaturalists, or into liberals and orthodox.
