Design• When designing a product several

issues must be taken into consideration to ensure the product works successfully.

• For example:• Size • Weight• Material

How do the following

products show design?

What about this.......

Produces oxygen.

Gives animals a home

Cleans water and

air

Produces material to build with

Produces food for animals

and humans

Trees- A perfectly designed product?

Finally, how does this show evidence of design............

Aim• To able to identify how nature shows

evidence of a design. • To relate the concept of a designer to the

argument for God

Design Argument• The argument from design finds its

origins in Aquinas’ Summa Theologica and is the fifth of his five ways of proving the existence of God.

• Aquinas argued from design qua regularity. He saw the overall order in the world as proof of a designer: ‘this being we call God.’

• Aquinas stated that everything works together to achieve order, despite the fact that inanimate objects have no mind or rational powers to achieve this.

• Aquinas explained his point by using the example of an arrow, saying that for an arrow to reach its destination it must be directed first of all by the archer. In the same way, ‘natural bodies’ seem to act in a regular fashion to reach a specific purpose. As they, like the arrow, are not able to direct themselves, there must be a God doing the directing.

Arguments for the Existence of GodThese types of argument are often called ‘Teleological’ arguments. They basically works like this:1. To design something takes intelligence and thought.2. The universe appears to have been designed.3. Therefore, a being with intelligence and thought

must have designed the universe.4. Only God could design something as complex as the

universe.5. Therefore, God must exist.

The philosopher, William Paley, used the idea of design to try and prove the existence of God.

• William Paley (1743-1805) then took this further when he formed his own version of the teleological argument in his book Natural Theology (1802).

• Paley uses the analogy of the watchmaker to explain his argument. He asks you to imagine a man walking across a heath. The man comes across a stone and a pocket watch and analyses both. His inspection of the stone leads him to conclude that it could have been there forever; there is nothing about the stone that leads the man to believe it lies on the heath for a particular reason.

Paley’s watch

Walking through the hills you come across a watch.

You notice how complex it is. It could not have

happened by chance/accident.

It must have had a ‘DESIGNER’.

The universe is far more complicated than a watch. If a

watch has a designer then surely the universe has.

The only thing powerful enough to make the

universe is God…SO… God must exist.

Watch the following video clip that explains Paley’s watch in more detail

I am too complicated to be an accident,

someone has designed me.

•Automatically adjusts to see in the dark•Can see underwater•Keeps a still, steady picture when your head moves•Cleans itself of dust with tears•Can reveal your emotions•Can repair itself to a certain extent•Can work well for about 95 years

Just think for a moment how amazing the human eye is.

The eye:

Design: When things show evidence of being planned for a purpose.

The Design Argument

Q. How does a camera show design? Q. What was the inspiration for the

first camera?

Q. How do these items show design?

Q. Why are they not better than the human body?

A ComputerA Battery

A Pocket Watch

Your brain is 4000 times more powerful than the largest supercomputer

Your heart keeps you going with 100,000 beats every day, 365 days a year, for life.

Your central nervous system can send millions of messagesto anywhere in your body, instantly.

The human body works in complete

harmony with itself

without any need of

conscious instruction from

you.

Pebble – simple – explanation = natural

Watch – complex – explanation = designer

Eye – complex – explanation = designer?

Make notes: William Paley (1743-1805)

Paley put forward the watch analogy to explain his design argument. Finding a stone would not puzzle us and we would know it to be a natural occurrence. However, if we found a

watch we would be puzzled. It is composed of finely adjusted parts. Its interaction serves a purpose = TO TELL THE TIME.

If things have order and purpose they usually point to an intelligent designer.

We can recognise elements of the watch argument in nature. Therefore, if we argue that:

Watch = watchmaker > both intelligent designs(ers).

World =World maker

The degree of creation are different but the same principle can be applied.

Paley’s Watch Analogy 2

This argument is an analogy – comparing one thing with something similar, so the second half of Paley’s argument compares the watch with the universe.

• Similarly, if you look at the world we live in you will see how complex it also is.

• You could examine it and see that it has very complex systems – weather, gravity, etc. It also has so many complex organisms living on it, perfectly suited to their environments.

• You would conclude that such complexity and harmony could not have just appeared randomly, but that it must have been designed somehow (like the watch was).

• You might also conclude that everything seems to be working together to a similar end.

• Therefore, you could finally conclude that there had to be an intelligent ‘world-maker’ who designed this universe and all of life with a purpose in mind.

• This ‘world-maker’ must be God, as God is the only being out-with the universe, and is the only intelligent, powerful and loving creator.
