Abstract

With his ontology of anxiety, as developed by Paul Tillich in his well-known work, “The Courage to Be”, he creates, by his own claim, a foundation for dealing with the phenomenon of anxiety in a variety of disciplines, which also serves as a foundation for the well-known American existential psychotherapist Rollo May. However, this does not remain a one-sided influence, but rather an interest in the works of both thinkers with reciprocal interdependencies.
