“It was not without difficulty that I obtained leave to try whether my mind, which had hitherto lain a perfect waste, was strong enough to understand and relish Feyjoo. But the contents of his pages came like the spring showers upon a thirsty soil. A man’s opinion of the first work he read when a boy, cannot safely be trusted; but, to judge from the avidity with which at the age of fifteen I devoured fourteen volumes on miscellaneous subjects, and the surprising impulse they gave to my yet unfolded faculties, Feyjoo must be a writer who deserves more notice than he has ever obtained from his countrymen. If I can trust my recollection, he had deeply imbibed the spirit of Lord Bacon’s works, together with his utter contempt of the absurd philosophy which has been universally taught in Spain, till the last third of the eighteenth century. From Bayle, Feyjoo had learned caution in weighing historical evidence, and an habitual suspicion of the numberless opinions which, in countries unpurified by the wholesome gales of free contending thought, are allowed to range unmolested, for ages, with the same claim to the rights of prescription as frogs and insects have to their stagnant pools. In a pleasing and popular style, Feyjoo acquainted his countrymen with whatever discoveries in experimental philosophy had been made by Boyle at that time. He declared open war against quackery of all kinds. Miracles and visions which had not received the sanction of the Church of Rome did not escape the scrutinizing eye of the bold Benedictine. Such, in fact, was the alarm produced by his works on the all-believing race for whom he wrote, that nothing but the patronage of Ferdinand VI. prevented his being silenced with the _ultima ratio_ of Spanish divines--the Inquisition.
