"Man is infinitely concerned about the infinity to which he belongs, from which he is separated, and for which he is longing. Man is totally concerned about the totality which is his true being and which is disrupted in time and space. Man is unconditionally concerned about that which conditions his being beyond all the conditions in him and around him. Man is ultimately concerned about that which determines his ultimate destiny beyond all preliminary necessities and accidents."

“North American Paul Tillich Society”

“conformism might approximate collectivism, not so much in economic respects, and not too much in political respects, but very much in the pattern of daily life and thought. Whether this will happen or not, and if it does to what degree, is partly dependent on the power of resistance in those who represent the opposite pole of the courage to be, the courage to be as oneself.”

“The existential attitude is one of involvement in contrast to a merely theoretical or detached attitude. “Existential” in this sense can be defined as participating in a situation, especially a cognitive situation, with the whole of one’s existence.”

“In a man like Friedrich von Schlegel the courage to be as an individual self produced complete neglect of participation, but it also produced, in reaction to the emptiness of this self-affirmation, the desire to return to a collective. Schlegel, and with him many extreme individualists in the last hundred years, became Roman Catholics. The courage to be as oneself broke down, and one turned to an institutional embodiment of the courage to be as a part.”

“Without the eros toward truth, theology would not exist.”

“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.”
