The annual Lowdham Book Festival runs from 15th June-1st July and offers a wide variety of literature related material.
In terms of Philosophy, the Lit & Phil tent (behind the village hall at Lowdham) promises an interesting (and free!) day of events, most pertinently, "A Good Story? A tour of ethics in five tall tales', with Will Buckingham from 4.15-5pm, which addresses such questions as "what does it mean to be good? and "how should we live our lives?", using five philosophers to help answer these questions.
