The Argument from DesignThe Argument from Design Also called the Teleological argument British philosopher William Paley

famously defended this claim with the

Analogy of finding a watch in a field… [S]uppose I found a watch upon the ground, and it should be inquired how the

watch happened to be in that place, I should hardly think … that, for anything I knew, the watch might have always been there. Yet why should not this answer serve for the watch as well as for [a] stone [that happened to be lying on the ground]?… For this reason, and for no other; namely, that, if the different parts had been differently shaped from what they are, if a different size from what they are, or placed after any other manner, or in any order than that in which they are placed, either no motion at all would have been carried on in the machine, or none which would have answered the use that is now served by it. –Paley, 1867

Teleological Argument continuedTeleological Argument continued The design of the universe is so

impressive and well organized that a designer must have made it.

Many variations and arguments are created within the Teleological argument.

How does Darwin’s theory fit in? Is this an inductive or deductive argument?

The Ontological ArgumentThe Ontological Argument Ontology refers to: ‘having to do with

the nature of existence.” The argument is based upon the

notion that for something to be perfect, it must exist. I. One can conceive of a being which has

every perfection (i.e., is most perfect). Such a being is called God.

II. Existence is a component of Perfection. Therefore, for God to be most perfect, he

must exist.

Moral Argument God’s ExistenceMoral Argument God’s Existence

Kant argued that the very existence of normative laws and morals is itself evidence for God’s Existence.

The claim is made the following way: I. Moral norms have authority II. If they have authority, their must be a reliable motive for

human beings to be moral III. No motive could exist without a Divine source IV. Therefore a God exists that provides such morals

Irrational Arguments for God’s Existence

Irrational Arguments for God’s Existence

Pascal’s Wager: Blaise Pascal imagine belief as one imagines placing a bet:

-God either exists or does not. Represented by: ∞ or 0

-One Either believe in God or do not. Represented by: B or D

B + ∞ = Eternal Reward

D + ∞ = Eternal Damnation

B + 0 = Missed out on a few pleasures (‘edifying faith’)

D + 0 = Ok and you had good times

Pascal argued that the reward for Belief is so great and the punishment so terrible, one ought to believe just in case God did exist. See page 94 for more detail.

Soren Kierkegaard’s Leap of FaithAnd Mysticism

Soren Kierkegaard’s Leap of FaithAnd Mysticism

Kierkegaard argued there was no definitive proof that God existed. Belief, therefore, was a choice based upon Faith. Faith is a personal choice, it cannot be shared with others as evidence for God’s existence.

Kierkegaard believed it was precisely because one does not know if God exists that faith is required. If one could know God existed, one risks nothing for eternal happiness.

Thus, one must take a Leap of Faith to ‘know’ God. Another claim is that one can know God through a Mystical experience (a

revelation or other-worldly experience). In that moment, one’s soul is directly contact by God.

Why is a Mystical Experience considered an irrational argument?
