ABSTRACT
What a world of difference exists between the relative calm of a Priestley or a Knox, with whom this volume began, and the last three theorists to be considered. True, Knox had been a little shrill in denunciation of 'Innovators' (and a little free with his capital letters of protest); one senses a certain defensiveness. But the foundations remained reasonably solid. True, Rousseau had earlier struck the messianic note, had questioned the whole basis of current civilisation; but clearly there were still many to spring to its defence and to take him to task in the name of 'right reason' or ancient precedent.
