This chapter explores in detail John Toland's intellectual transactions with Lord Robert Molesworth, one of the commonwealth politicians in his circle, in order to allow a more reflective appreciation of the function of his learning and ideas. The first result of Toland's relationship with Molesworth was the analysis of the Druidical past as a Complete History of Priestcraft. The chapter also discusses Toland's idea, contained in his Clidophorus, that the tyranny of priestcraft meant that the truth could rarely be spoken in public.
