Psalm 42 states that "As the deer pants for water, so I long for you, O God", but did you know that there's an actual argument for the existence of God, and even of heaven, from the existence of certain human desires? C.S. Lewis was captivated by this theme, and he produced the twentieth century’s principal thematic and argumentative engagement with what has come to be known by philosophers as 'the argument from desire'. This workshop will explore Lewis' apologetic engagement with desire and how it points us to God.
