- Four Classical Arguments
- The Argument from First Cause
- Everything must have a cause
- Causal Chains cannot go on forever
- Therefore there must be a first cause, and that is God.
- The Argument from Design
- Something in the universe or the universe itself seems to be designed
- Therefore a designer must exist and that is God
- The Argument from the Anthropic Principle
- The universal constants are fine tuned for the existence of humans.
- Therefore there must have been a God to fine tune the universe for our existence
- The Ontological Argument
- God is a being than which nothing greater can be conceived.
- Assume that God does not exist.
- An existent God is a being greater than a non-existent one
- If God did not exist, then we could conceive of a being greater than God -- A God that exists.
- This is a contradiction, therefore (2) must be false and God exists
- Four Subjective Arguments
- The Argument from Coincidence
- There have been some remarkable coincidences.
- There must be a reason for those coincidences.
- That reason is God.
- The Argument from Prophecy
- A holy book makes prophesies.
- A holy book or the adherents of it report that those prophesies have come true.
- Therefore whatever else is in the book, such as the claim that God exists must be true.
- The Argument from Subjectivity and Faith
- People feel sure that God exists.
- Therefore God exists.
- The Argument from Divine Interventions, Miracles and such
- A miracle occurs, perhaps as a response to prayer.
- God exists as evidenced by the divine intervention
- Four Psycho-Mathematical Arguments
- The Argument from Redefinition
- God is Love or Goodness or some other such thing.
- Love, goodness or whatever, clearly exists.
- Therefore God exists.
- The Argument from Cognitive Tendency
- Some cognitive tendencies suggest the existence of an all-powerful agent.
- God must be that all-powerful agent
- The Universality Argument and Morality
- Across cultures, the similarities in moral values are quite apparent.
- They must come from God
- The Gambling Argument
- We can choose to believe or not in God.
- If we choose wrongly then negative consequences of choosing to disbelieve are greater than the negative consequences of choosing to believe.
- Therefore it is prudent to believe.
These are the arguments for God. There are numerous subtle variations on them, but essentially, as far as I can tell those who claim that God exists do so based on one or more of these arguments and nothing else.
Why should I believe that there is a God? What are your reasons? Are any of these reasons valid? If your reasons do not fall into any of the above groupings, please let us know why you believe. If you believe for a combination of these reasons, select the strongest one and explain why.
