Is beauty a guide to truth? There is one story told by science which states that the only things that can be classed as true are facts: things that can be measured, quantified and verified. It denies truth to the spiritual, the moral or the aesthetic because these do not fit scientific criteria. They are classed as meaningless, figments of the imagination - the misfirings of neurons. David and Ard challenge this bleak vision, and ask if it is correct, why is it that we are so moved by beauty, and why do so many truths reveal themselves as beautiful? The answers they each reach are very different, but through their journey and discussions they reveal how profoundly our sense of beauty is connected to both our quest for truth, but also our search for meaning.
