Mortality and Faith is the second half of an autobiography of David Horowitz whose first installment, Radical Son, was published more than twenty years ago. It completes the account of his life from where the first book left off to his seventy-eighth year.

In contrast to Radical Son whose focus was his political odyssey, Mortality and Faith was conceived as a meditation on age, and on our common progress towards an end which is both final and opaque. These primal facts affect all we see and do, and force us to answer the questions as to why we are here and where we are going with conjectures that can only be taken on faith. Consequently, an equally important theme of this work is its exploration of the beliefs we embrace to answer these questions, and how the answers impact our lives.
