 In 1966, philosopher John Hick discussed the similarities of the preceding theodicies, calling them all "Irenaean".He supported the view that creation is incomplete and argued that the world is best placed for the full moral development of humans, as it presents genuine moral choices.British philosopher Richard Swinburne proposed that, to make a free moral choice, humans must have experience of the consequences of their own actions and that natural evil must exist to provide such choices.
