Note 12 — INTRODUCTION.

Few authors are better deserving of an extended biography, a desideratum which, in an age characterised by its want of literary research, is not likely to be soon supplied, than Thomas Erastus, whose theological, philosophical, and medical celebrity entitle him to rank with the greatest men of his century. At present we have to collect all that is known of his life from various scattered and contradictory sources. John Webster, in his Displaying of Supposed Witchcraft, contrary to the usual candour and fairness of his judgments, speaks slightingly of Erastus. There was, however, a sufficient reason for this. Erastus had shown up the empiricism of Webster's idol Paracelsus, and was in great disfavour with the writers of the Anti-Galenic school.
