Critically assess the Cosmological argument for the existence of God. The Cosmological argument infers an existence of a God from looking at the cosmos and the phenomena within it. Many philosophers and prominent thinkers have either rejected the claim that the creator of the universe is God, or have refuted St Thomas Aquinas’ thinking and reasoning in his 3 ways of proving Gods existence which constitutes the cosmological argument; as outlined in ‘Summa Theologica’. These criticisms are what I am going to be examining throughout this essay. One of Aquinas’ ways of proving God’s existence; ‘the uncaused causer’, states that every cause in the universe has an effect, the chain of cause and effect must have a terminus to avoid infinite regress. Aquinas rejects infinite regress because it denotes that there cannot be an answer to the question “what is the explanation?” Therefore there must be a necessary being that started the chain, this for Aquinas is God but this is not a satisfactory answer for everyone. Bertrand Russell, somewhat like Aristotle, states that the universe is a “brute fact”, although unlike Aristotle did not see that there needed to be a Prime Mover or Uncaused Cause. Russell made another criticism when he suggested that one cannot go from saying that every event has a cause thus the whole universe has a cause, it is like moving from saying that every human being has a mother to the claim that the human race as a whole has a mother. One cannot move from individual causes to the totality (whole, everything) has a cause. This is the line of thinking Hume had when he stated that the Cosmological argument commits the fallacy of composition. It assumes that characteristics of parts of a thing are also characteristics of the whole. The fact that each thing in the universe has a cause does not mean that the universe in its entirety has a cause.
