" However this may be, it can hardly be doubted that with Justinian’s persecution of non-Christians, heretics, and philosophers (A.D. 529), the dark ages began. The Church followed in the wake of Platonic-Aristotelian totalitarianism, a development that culminated in the Inquisition. The theory of the Inquisition, more especially, can be described as purely Platonic. It is set out in the last three books of the Laws, where Plato shows that it is the duty of the shepherd rulers to protect their sheep at all costs by preserving the rigidity of the laws and especially of religious practice and theory, even if they have to kill the wolf, who may admittedly be an honest and honourable man whose diseased conscience unfortunately does not permit him to bow to the threats of the mighty.
