to the Geological Society of London in 1831 which declared that "No opinion can be heretical, but that which is not true… Conflicting falsehoods we can comprehend; but truths can never war against each other. I affirm, therefore, that we have nothing to fear from the results of our enquiries, provided they be followed in the laborious but secure road of honest induction. In this way we may rest assured that we shall never arrive at conclusions opposed to any truth, either physical or moral, from whatever source that truth may be derived." For these men, science could not be out of harmony with religion, and in a sense it was religion. Under pressure in the fourth year, Darwin worked hard at his studies, getting tuition in theology by Henslow. Darwin became particularly interested in the Revd William Paley's Evidences of Christianity and Principles of Moral and Political Philosophy, which were set texts. The latter was becoming outdated. It opposed arguments for increased democracy, but saw no divine right of rule for the sovereign or the state, only "expediency". Government could be opposed if grievances outweighed the danger and expense to society. The judgement was "Every man for himself". These ideas had suited the conditions of reasonable rule prevailing when the text was published in 1785, but in 1830 they were dangerous ideas at a time when the French king was deposed by middle class republicans and given refuge in England by the Tory government, and resulting radical street protests demanded suffrage, equality and freedom of religion. Paley's text even supported abolition of the Thirty-nine Articles of the Anglican faith which every student at Cambridge (and Oxford University) was required to sign. Henslow insisted that "he should be grieved if a single word of the Thirty-nine Articles were altered" and emphasised the need to respect authority. Darwin later wrote that he was convinced that he "could have written out the whole of the Evidences with perfect correctness, but not of course in the clear language of Paley. The logic of this book and as I may add of his Natural Theology gave me as much delight as did Euclid." After doing particularly well in his final exam questions on Paleys' books, Darwin read Paley's Natural Theology which set out to refute David Hume's argument that the teleological argument for "design" by a Creator was merely a human projection onto the
