The book is based on Barth's assumption of 1933 that «the true Hegeltime..is still to begin.» That assumption implies: Barth was essentially correct in his critique of natural theology. That critique implies that the only presupposition theology can accept is God's self-revelation. Presuppositionless theology is in structure identical to presuppositionless philosophy such as that of Hegel. Triplicism is the «community of freedom», reflecting from within self-disclosing truth. Such self-reflection implies a natural theology, for it is inherently reasonable. It is of necessity critical of positions that operate with presuppositions, such as any transcendentalism, but also hermeneutics. The book follows in structure the six theses of the Barmen Declaration of 1934, and touches most major theological positions of the present time.
