"Hobbes had systematized Bacon, without, however, furnishing a proof for Bacon's fundamental principle, the origin of all human knowledge from the world of sensation. It was Locke who, in his Essay on the Human Understanding, supplied this proof.
"Hobbes had shattered the theistic prejudices of Baconian materialism; Collins, Dodwall, Coward, Hartley, Priestley similarly shattered the last theological bars that still hemmed-in Locke's sensationalism. At all events, for practical materialists, Theism is but an easy-going way of getting rid of religion."[B]
Thus Karl Marx wrote about the British origin of modern materialism. If Englishmen nowadays do not exactly relish the compliment he paid their ancestors, more's the pity. It is none the less undeniable that Bacon, Hobbes, and Locke are the fathers of that brilliant school of French materialists which made the eighteenth century, in spite of all battles on land and sea won over Frenchmen by Germans and Englishmen, a pre-eminently French century, even before that crowning French Revolution, the results of which we outsiders, in England as well as in Germany, are still trying to acclimatize.
There is no denying it. About the middle of this century, what struck every cultivated foreigner who set up his residence in England, was, what he was then bound to consider the religious bigotry and stupidity of the English respectable middle-class. We, at that time, were all materialists, or, at least, very advanced freethinkers, and to us it appeared inconceivable that almost all educated people in England should believe in all sorts of impossible miracles, and that even geologists like Buckland and Mantell should contort the facts of their science so as not to clash too much with the myths of the book of Genesis; while, in order to find people who dared to use their own intellectual faculties with regard to religious matters, you had to go amongst the uneducated, the "great unwashed," as they were then called, the working people, especially the Owenite Socialists.
