This study discusses the mind-body problem, arguing that the human person is best understood as an animal who is also spirit. Braine suggests that human beings should be described holistically, in the tradition of Aristotle and Thomas Aquinas. His final chapter explores a doctrine of immortality.

Basing his argument for the existence of God on the continuous nature of the temporal world, Braine here posits that the philosophy of religion cannot be continued as a separate discipline: the solution of its problems will be the fruit of the correct telesis of the problems of general philosophy in their complex interrelationships.
