Suppose you have joined freemasonry recently and are working through the three ceremonies of initiation, passing and raising. You enjoy their uplifting admonitions to personal improvement and want further reading, as it were, to broaden your understanding of the ideas presented in the degrees as well as the intellectual currents that informed them.
Reading, though, is so twentieth-century. You want to listen to easily digestible podcasts that deliver the thinking of top-drawer academics in no more time than it takes walk to commute to work. What you need is BBC Radio 4’s programme on the history of ideas, In Our Time.
What follows then is an entirely unofficial, biased(!) and personal list of IOT episodes you could listen to in the days immediately following each of the three degree ceremonies, with a general category to give a flavour of some of the ideas that inform masonic culture.
