is reasonable; it was necessary to prove that it is real and rests on a solid historical basis. This was the question raised in an acute form by the criticisms of Hume and Middleton (1748) on miracles. The ablest answer was given by Paley in his Evidences of Christianity (1794), the only one of the apologies of that age which is still read, though it has ceased to have any value. Paley's theology illustrates how orthodox opinions are coloured, unconsciously, by the spirit of the time. He proved (in his Natural Theology) the existence of God by the argument from design—without taking any account of the criticisms of Hume on that argument. Just as a watchmaker is inferred from a watch, so a divine workman is inferred from contrivances in nature. Paley takes his instances of such contrivance largely from the organs and constitution of the human body. His idea of God is that of an ingenious contriver dealing with rather obstinate material. Paley's "God" (Mr. Leslie Stephen remarked) "has been civilized like man; he has become scientific and ingenious; he is superior to Watt or Priestley in devising mechanical and chemical contrivances, and is therefore made in the image of that generation of which Watt and Priestley were conspicuous lights."
