1. One of the classic arguments for the existence of God It is a posteriori and inductive Begins with two basic observations: The world seems to contain both REGULARITY and PURPOSE

2. Regularity and Purpose Consider the regular motion of planets or the consistency of a beating heart Very unusual for such perfect organisation to occur naturally – suggests it has been designed, and this designer could only be God Consider also the wings of a bird or the gills of a fish They have a specific purpose which they achieve very efficiently Seems very unlikely they could simply have popped into existence – consider the complexity of the eye Again – suggests they have been designed

3. Arguments FOR design vs arguments FROM design Some arguments start by looking at the complexity in the world, eg the complexity of living beings They argue that these observations of the world lead to the conclusion that there must be a designer - they are arguments FOR design An alternative is to start with certain designed objects such as a watch We then notice a certain analogy between mechanical objects and the world So we conclude that just as the watch is designed, the world must be This is an argument FROM design, as we start by looking at something which is designed
