In the course of the sixteenth century the Ottoman Sultans conquered Bagdad, Hungary, Egypt and most of North Africa, and their fleet made them masters of the Mediterranean. They very nearly took Vienna, and they exacted it tribute from the Emperor. There were but two items to offset the general ebb of Christian dominion in the fifteenth century. One was the restoration of the independence of Moscow (1480); the other was the gradual reconquest of Spain by the Christians. In 1492, Granada, the last Moslem state in the peninsula, fell to King Ferdinand of Aragon and his Queen Isabella of Castile.
But it was not until as late as 1571 that the naval battle of Lepanto broke the prick of the Ottomans, and restored the Mediterranean waters to Christian ascendancy.
XLIX
THE INTELLECTUAL REVIVAL OF THE EUROPEANS
Throughout the twelfth century there were many signs that the European intelligence was recovering courage and leisure, and preparing to take up again the intellectual enterprises of the first Greek scientific enquiries and such speculations as those of the Italian Lucretius. The causes of this revival were many and complex. The suppression of private war, the higher standards of comfort and security that followed the crusades, and the stimulation of men’s minds by the experiences of these expeditions were no doubt necessary preliminary conditions. Trade was reviving; cities were recovering ease and safety; the standard of education was arising in the church and spreading among laymen. The thirteenth and fourteenth centuries were a period of growing, independent or quasi-independent cities; Venice, Florence, Genoa, Lisbon, Paris, Bruges, London, Antwerp, Hamburg, Nuremberg, Novgorod, Wisby and Bergen for example. They were all trading cities with many travellers, and where men trade and travel they talk and think. The polemics of the Popes and princes, the conspicuous savagery and wickedness of the persecution of heretics, were exciting men to doubt the authority of the church and question and discuss fundamental things.
We have seen how the Arabs were the means of restoring Aristotle to Europe, and how such a prince as Frederick II acted as a channel through which Arabic philosophy and science played upon the renascent European mind. Still more influential in the stirring up of men’s ideas were the Jews. Their very existence was a note of interrogation to the claims of the church. And finally the secret, fascinating enquiries of the alchemists were spreading far and wide and setting men to the petty, furtive and yet fruitful resumption of experimental science.
And the stir in men’s minds was by no means confined now to the independent and well educated. The mind of the common man was awake in the world as it had never been before in all the experience of mankind. In spite of priest and persecution, Christianity does seem to have carried a mental ferment wherever its teaching reached. It established a direct relation between the conscience of the individual man and the God of Righteousness, so that now if need arose he had the courage to form his own judgment upon prince or prelate or creed.
As early as the eleventh century philosophical discussion had begun again in Europe, and there were great and growing universities at Paris, Oxford, Bologna and other centres. There medieval “schoolmen” took up again and thrashed out a series of questions upon the value and meaning of words that were a necessary preliminary to clear thinking in the scientific age that was to follow. And standing by himself because of his distinctive genius was Roger Bacon (circa 1210 to circa 1293), a Franciscan of Oxford, the father of modern experimental science. His name deserves a prominence in our history second only to that of Aristotle.
His writings are one long tirade against ignorance. He told his age it was ignorant, an incredibly bold thing to do. Nowadays a man may tell the world it is as silly as it is solemn, that all its methods are still infantile and clumsy and its dogmas childish assumptions, without much physical danger; but these peoples of the middle ages when they were not actually being massacred or starving or dying of pestilence, were passionately convinced of the wisdom, the completeness and finality of their beliefs, and disposed to resent any reflections upon them very bitterly. Roger Bacon’s writings were like a flash of light in a profound darkness. He combined his attack upon the ignorance of his times with a wealth of suggestion for the increase of knowledge. In his passionate insistence upon the need of experiment and of collecting knowledge, the spirit of Aristotle lives again in him. “Experiment, experiment,” that is the burthen of Roger Bacon.
Yet of Aristotle himself Roger Bacon fell foul. He fell foul of him because men, instead of facing facts boldly, sat in rooms and pored over the bad Latin translations which were then all that was available of the master. “If I had my way,” he wrote, in his intemperate fashion, “I should burn all the books of Aristotle, for the study of them can only lead to a loss of time, produce error, and increase ignorance,” a sentiment that Aristotle would probably have echoed could he have returned to a world in which his works were not so much read as worshipped—and that, as Roger Bacon showed, in these most abominable translations.
