You can download all three of Professor Hart's lectures as MP3 files as well as viewing a series of short videos produced by the Centre for Public Christianity while Professor Hart was here to present the lectures (here).
In the first of the videos below Professor Hart discusses with Greg Clarke the role that the imagination plays in our experience of God and faith. He argues that there is a significant difference between the 'imaginary' and 'imagination'. Imagination he suggests is "the capacity to picture things not present to us in our senses", and can help us to understand God and to gain greater insights into his reality. He also offers some brief reflections on the role of the imagination in science.
You can access four separate short videos on this topic plus MP3 downloads of all three lectures that Professor Hart delivered in 2008 at New College (here).
