Aquinas A Beginner's Guide

One of the most influential philosophers and theologians in the history
of Western thought, St Thomas Aquinas established the foundations for
much of modern philosophy of religion, and is famous for his arguments
for the existence of God. In this cogent and multifaceted introduction
to the great Saint's work, Edward Feser argues that you cannot fully
understand Aquinas's philosophy without his theology and vice-versa.
Covering his thoughts on the soul, natural law, metaphysics, and the
interaction of faith and reason, this will prove a indispensible
resource for students, experts or the general reader.
