PREFACE
IN the Middle Ages the old world had passed, and the vision of a new world came near to the eager and passionate hearts of many peoples. Lincoln and Wells, Amiens and Chartres, Florence and Assisi tell us of the glory of that vision; and bear witness of its flight: for with Gilbert, Galileo, Harvey and Newton the Middle Ages themselves became a phantom, and again the spirit of a new world appeared. Thus in the phases of time the world dies and is born again; fulfilling greater destinies. But the new are born in the cold bed of the elder worlds, and the young life is chilled, or a lustier offspring turns unnaturally to curse the dead; so in their decrepitude lay the Middle Ages upon modern life; and the Middle Ages were accursed, until certain pious men sought to reanimate their vestments and their formulas, and to set the hands back on the dial of the centuries; as manyminded man seeks wistfully to reanimate the simple wonders and beliefs of his childhood. Their ministry was no more than pious; the method of modern history wins the fruits of the past while casting away the shadow of its withered branches. This comparative method, first applied to the art and romance of the Middle Ages, so that every dilettante may now discourse to us of their evolution, has been applied also to the thought of the period; but its results, laid up in the closets of a few scholars, are as yet unfamiliar. It may then become one, who in no sense a scholar has strayed into these secret places, to try to distribute some lessons of the medieval thought which, to many of us, seems as sere and outworn as did the relics of Gothic shrines to our great-grandfathers. For, as in those medieval generations which lay nearest us the furnace had cooled, impatiently we had thrown metal and dross aside, and let our contempt for the dryness and pedantry of its latter days prevent our vision of the earlier time when the passion for knowledge bore up the world, and sought even to contain it. That dogma is not eternal is manifest to every wanderer in the streets of Toledo, yet the historian may well recall us to the study of a time when, by mystical or intellectual inspirations, men strove eagerly to know the meaning of life, its origins, and its issues; and may lead us to the discovery of the seeds and wells of its fertility. The Greeks prophesied that before man can determine his place and service in this world he must form some theory of the world as a whole; the ages of faith prophesied that great deeds must be born of great faith and of great conceptions.
To those who live only in the past, or only in the present, there seems in the discriminations of the comparative historian to be a certain cold-bloodedness. Are not the ears of this critic, so aloof from the murmuring of creed and controversy, are they not deaf to the voices of the spirit which he would interpret to us? A distinguished bishop who was among my hearers, with the fervour and gentle humour so well known in him, rallied me not for celebrating science but for putting religion to rout. Yet in our own day surely the argument is changed, not in form only but in very nature; so changed by the conceptions of evolution, which have entered the mind of churchman and layman alike, that not a few speculative beliefs are changing sides without the knowledge of the disputants; and he who thinks himself a defender of the faith may have joined the revolt. But if we no longer carry the colours of the troops of the past we shall collect our lessons from its strategies; and for one of these lessons a prelate of the King will give thanks with me, that his supremacy has palsied the arm of the inquisitor to strengthen that of the apostle.
An unsystematic reader of a subject finds it out of his power to make due acknowledgment of the help and advantage derived from expert authors. Much of the matter had seeded itself insensibly in his brain in the course of general reading and conversation; much of it again had been obtained more carefully from sources now forgotten. To the following authors I know I am profoundly indebted, as I am to many others to whose names and works I can now give no reference:

(The six last works are cited as being especially useful, among many others, to show the extent to which modern physiology, from Harvey onwards, is based upon vivisection; and that it could not have arisen or thriven otherwise. It was by the test of many vivisections that Plumpius was led to the honourable withdrawal of his opposition to Harvey.)
INTRODUCTION 1
IN the many Harveian Orations which have been delivered since the death of the founder of modern physiology the direct aspects of his honour and of his work have been exhausted; of late years the orators have concerned themselves with indirect aspects. Some of my friends have said to me that they lack a perspective view of Harvey and his work; that even highly educated men have little sense of his relation to medieval thought, or of the evolution of medieval into modern thought. Of the several stars of the constellation – of Copernicus, Gilbert, Galileo, Harvey – they had some knowledge; but how came Harvey to be at Padua? how did science spring up in North Italy? did science arise out of the womb of medicine, or contrariwise? why did natural science not flourish in the thirteenth century, and was it not a great misfortune for Europe that it did not then flourish? what were the systems of thought which in the Middle Ages preceded, encouraged or thwarted the travail of the human mind, and what of good or ill do we owe to them? These and such questions it seemed not unfitting that a Harveian Orator of this latter day should consider. Now on the philosophy of the Middle Ages, and on its relation to the era of positive science of which Harvey was perhaps the chief pioneer, there lay in a drawer in my cabinet the confused and occasional notes of many years. An interest in this thorny subject, sown in my mind at first by accident, and reawakened by these enquiring friends, had for me the charms of an old fancy, and I trust some brief essay thereon may have a temporary service; if, that is, I can touch the imagination of my hearers, and after some broken fashion bring before them a vision of the nations swayed hither and thither upon the face of Europe by a thirst for knowledge of a kind different, both in its methods and in its aims, from our own.
This oration cannot have the merit of an original study. Had I the
