1 April has become known as "World Atheist Day" - so in today’s feature, we are going to look at the meaning of atheism, arguments for and against the existence of God, and examine some of the reasoning on modern day "celebrity" atheists such as Richard Dawkins and Peter Singer. Christian Stephens from the Theology Department at the University of Notre Dame, and Fr. Brendan Purcell, Catholic Priest and Philosophy Lecturer, join Monica Doumit, the Coordinator of Catholic Talk, for a conversation about Atheism in this podcast!
