We don’t or can’t know if God exists. agnosticism Is this the most reasonable position to take, or are there strong arguments in favor of or against belief? Buddhism might be considered an agnostic religion.

Classic Arguments for Theism St. Thomas Aquinas 1225 – 1274 God is evident in basic facts about the world of our experience. St. Thomas Aquinas was an important figure in the history of the Catholic Church. He combined the conceptual framework of Greek philosophy, especially Aristotle, with the core beliefs of Medieval Christianity. His ideas continue to provide the basis for contemporary Catholic philosophy and theology.

Classic Arguments for Theism William Paley c. 1743 – 1805 The work of God is evident in the complexity of the natural world. William Paley was an influential English Protestant minister of the 18th Century. His arguments are still popular among contemporary “creationists” and backers of “intelligent design theory.”

Slide 47

Slide 47 text

Classic Arguments for Theism William Paley c. 1743 – 1805 The work of God is evident in the complexity of the natural world. If we found a watch on a deserted island we would conclude that it was designed by an intelligent person. Likewise with living organisms – they too are best explained by a designer Thus a God who designed and created living organisms must exist. the teleological argument

Classic Arguments for Theism If we found a watch on a deserted island we would conclude that it was designed by an intelligent person. Likewise with living organisms – they too are best explained by a designer Thus a God who designed and created living organisms must exist. the teleological argument This is an “argument to the best explanation” which claims that the best explanation for the complexity of living things is that there is a God who created them.

Classic Arguments for Theism If we found a watch on a deserted island we would conclude that it was designed by an intelligent person. Likewise with living organisms – they too are best explained by a designer Thus a God who designed and created living organisms must exist. the teleological argument To see whether this is true we need to know whether there are other workable explanations.

Slide 54

Slide 54 text

Classic Arguments for Theism St. Anselm c. 1033 – 1101 Reason alone can convince us to believe that God exists. Anselm of Canterbury was born in France but ascended through the ranks of the Medieval Church to become Archbishop of Canterbury, the head of the Church in England. His philosophical work was an early attempt to systematize Church doctrine and establish it on a rational basis.

Slide 55

Slide 55 text

Classic Arguments for Theism St. Anselm c. 1033 – 1101 Reason alone can convince us to believe that God exists. We can imagine a perfect being. If this being did not exist, it would lack something and thus not be perfect. Thus a perfect being (God) must exist. the ontological argument

Slide 56

Slide 56 text

Classic Arguments for Theism We can imagine a perfect being. If this being did not exist, it would lack something and thus not be perfect. Thus a perfect being (God) must exist. the ontological argument This argument is an example of a reductio ad absurdum in that it claims that the opposite of what it is trying to prove – the non-existence of a being defined as perfect – makes no sense.

Slide 57

Slide 57 text

Classic Arguments for Theism We can imagine a perfect being. If this being did not exist, it would lack something and thus not be perfect. Thus a perfect being (God) must exist. the ontological argument This argument seems to be cheating – can we really conclude anything about reality based just on our definition of the concept “perfect being?”

Slide 58

Slide 58 text

Classic Arguments for Theism We can imagine a perfect being. If this being did not exist, it would lack something and thus not be perfect. Thus a perfect being (God) must exist. the ontological argument Is existence really a feature of things in the way this argument seems to require?

Slide 59

Slide 59 text

Classic Arguments for Theism We can imagine a perfect being. If this being did not exist, it would lack something and thus not be perfect. Thus a perfect being (God) must exist. the ontological argument What does this very abstract idea of a perfect being have to do with the God of religion?

Slide 63

Slide 63 text

An Argument for Atheism David Hume c. 1711 – 1776 What can we really know based on the available evidence? David Hume was a major figure in the Scottish Enlightenment. He sought to apply the scientific method to the study of human knowledge. This often led him to skeptical conclusions about how much we really can claim to know. He is now recognized as a pioneer in cognitive psychology as well being an influential philosopher.

Slide 64

Slide 64 text

An Argument for Atheism David Hume c. 1711 – 1776 What can we really know based on the available evidence? If there is an all-powerful, all- knowing and all-good God, then evil should not exist. But there clearly is evil in the world. This gives us a strong reason to doubt the existence of such a God. the argument from evil

This gives us a strong reason to doubt the existence of such a God. the argument from evil The most popular defense of God is the appeal to free will - God made us free to choose good or evil and this requires evil in the world.

Slide 73

Slide 73 text

An Alternate Argument for Theism Blaise Pascal 1623 – 1662 We are all compelled to gamble. Blaise Pascal was a mathematician and deeply religious philosopher. He was one of the inventors of probability theory and applied probabalistic reasoning to the question of religious belief.

Slide 74

Slide 74 text

An Alternate Argument for Theism Blaise Pascal 1623 – 1662 We are all compelled to gamble. We have no conclusive evidence for the existence or non-existence of God. But the risk of not believing in case God exists –punishment in hell– far out- weighs whatever benefit we might get from not believing should God not exist. Thus we have a strong reason to believe that God exists. Pascal’s wager

But the risk of not believing in case God exists –punishment in hell– far out- weighs whatever benefit we might get from not believing should God not exist.

Pascal’s wager Even if the probability of God’s existence is very low, the infinite penalty involved in not believing should God actually exist is too great to ignore.

And can we believe whatever we may want or feel the need to believe?

The Buddhist Perspective Siddhartha Gautama c. 563 – c. 483 BCE What we believe about ultimate questions is less important than how we live. Arguing about the nature of God, the soul, life after death is like arguing about the details of the arrow after having been shot with one. It is far more important to pull the arrow out than worry about who shot it and from how far away.
