Mellor, have objected to Tennant's particular use of probability theory and have challenged the relevance of any kind of probabilistic reasoning to theistic belief." Richard Swinburne's "contributions to philosophical theology have sought to apply more sophisticated versions of probability theory to the question of God's existence, a methodological improvement on Tennant's work but squarely in the same spirit". He uses Bayesian probability "taking account not only of the order and functioning of nature but also of the 'fit' between human intelligence and the universe, whereby one can understand its workings, as well as human aesthetic, moral, and religious experience". Swinburne writes: Swinburne acknowledges that his argument by itself may not give a reason to believe in the existence of God, but in combination with other arguments such as cosmological arguments and evidence from mystical experience, he thinks it can. While discussing Hume's arguments, Alvin Plantinga offered a probability version of the teleological argument in his book God and Other Minds: Following Plantinga, Georges Dicker produced a slightly different version in his book about Bishop Berkeley: The Encyclopædia Britannica has the following criticism of such arguments: Fine-tuned universe A modern variation of the teleological argument is built upon the concept of the fine-tuned universe: According to the website Biologos: Also, the fine-tuning of the Universe is the apparent delicate balance of conditions necessary for human life. In this view, speculation about a vast range of possible conditions in which life cannot exist is used to explore the probability of conditions in which life can and does exist. For example, it can be argued that if the force of the Big Bang explosion had been different by 1/10 to the sixtieth power or the strong interaction force was only 5% different, life would be impossible. Renowned physicist Stephen Hawking estimates that "if the rate of the universe's expansion one second after the Big Bang had been smaller by even one part in a hundred thousand million million, the universe would have re-collapsed into a hot fireball due to gravitational attraction". In terms of a teleological argument, the intuition in relation to a fine-tuned universe would be that God must have been responsible, if achieving such perfect conditions is so improbable. However, in regard to fine-tuning, Kenneth Einar Himma writes: "The mere fact that it is enormously improbable that an event occurred... by itself, gives us no reason to think that it occurred
