?” This was the one and the only way I could argue Gods existence before I read Thomas’ five ways.Nowadays it is biology, rather then philosophy, that is called in aid by the argument of design. Some has argued that evaluation has a direction, a tendency to produce organisms of ever-greater complexity and ever-higher consciousness, which is the key to the future. Even Darwin’s theory of natural selection merely inserts an extra step between the phenomena to be explained and its ultimate explanation. Darwin’s success proved that lower animals did not have minds. ‘Now things which lack awareness do not tend towards a goal unless directed by a something with awareness and intelligence, like an arrow by an archer. Therefore there is some intelligent being by whom everything in nature is directed to a goal, and this we call God.’Five ways can not be separated from its medieval background. Aquinas’ arguments would have to be modernized to withstand contemporary opposition of our days. But the thing that was the most appealing to me in St. Thomas’s work was its purity. ‘Acceptance of the truth of divine revelation presupposes the gift of the theological virtue of faith in believer’. Faith is prior to hope and charity.Some people might say that proof of God’s existence empty of concept.
