Abstract
A treatment of act and being illustrating the general claim that the problems of philosophy can be answered only by a revelational theology. Beginning with a slapdash treatment of transcendental philosophy and its idealistic outgrowths, as well as phenomenological and existential ontologies, supposedly showing the necessary impasses of philosophy when left to its own devices, Bonhoeffer moves to a treatment of the being and act both of God's revelation per se and of the men to whom God is revealed. Man "in Adam" cannot resolve his act and being into unity; man "in Christ" can.--R. C. N.
