The debates on IAI tv address the pressing issues of our time. The topics and speakers are the outcome of a stringent editorial process. From sub-atomic physics and philosophical logic to global politics and aesthetics, we do not ask our speakers to simplify for a public audience or to engage in sound bites but to make their opinions direct and clear to their peers in the debate.

Our hosts are critical to ensuring this takes place. It is their difficult and challenging role to insist that questions are answered, that speakers do not hide behind their authority, fame or expertise, and that conclusions are drawn. As a result our hosts are often experts in their own right with the confidence to challenge the leading thinkers in the particular field on their own turf.
