Strengths and weaknesses of the cosmological argument.

HideShow resource information


  • Saying the universe has always existed is not a sufficient reason to explain its existence.
  • Science supports a beginning to the universe. The big bang theory suggests that the universe is not infinite.
  • As we are constantly adding events to time, time can not be infinite as you can not add to infinity.
  • Copleston would argue that there must be a first cause to explain the existence of the universe.


  • Even if we accept that there is an uncaused cause, must this be the God of Christianity?Could it not simply be the big bang-a scientific, not a religious event,
  • Saying the universe has always existed is not a sufficient reason to explain its existence
  • Steady state theory is challenge to the cosmological argument as it rejects the idea of a beginning to the universe. This theory provides a scientific explanation that would undermine the cosmological argument.
  • Aquinas argues that all things have a cause but that God does not. This is a direct contradiction of his own argument . Why is God the exception to the rule?
  • The cosmological argument is a fallacy of composition because it assumes that just because each part of the universe is caused it does not mean that the universe as a whole was caused.


There are more weaknesses than strengths to Aquinas' cosmological argument.

With the evaluation you would have to assess the strength of the arguments, not just the number of arguments on each side.
