P1 - Design Argument Flashcards
What is a posteriori
Arguments based on sense experience, we observe the world through touch, taste, hearing, smell and sight, and we draw conclusions form what our senses tell us
What is an inductive argument
Where we use premises to supply strong evidence for the truth of the conclusion
They are about what is probably true, they give us new knowledge
They can be used to argue from what we see in the world back to the supposed cause
Paley’s argument as inductive and a posteriori
Since his argument is a posteriori and inductive, his conclusion that the universe was designed is at best probably true, and it might turn out to be false
Paley’s argument, based on three particular observations about the world
Complexity: the complexity of the natural world, looks at complex biological organisms and organs
Qua-Regularity: the regularity of orbits, comets, moons and planets and seasons of the year
Qua-Purpose: observes machines humans built which are built for a purpose, complexity and regularity implies that it has a purpose
Summary of Paley’s inductive design argument (on the basis of his observations)
Some objects in the world show clear evidence that they are designed due to complexity and regularity from which we can infer that they were made for a purpose
The universe appears to exhibit complexity and regularity, from which we can infer that it was made for a purpose
So it is likely that the universe was designed
What is natural theology
The view that questions about God’s existence, nature and attributes can be answered without referring to scripture or to any other form of special revelation, by using reason, science, history and observation
Summary of Paley’s analogically design argument
- A watch has complex parts, each with a function, and the parts work together for a specific purpose
- So the watch must have been designed by a watch maker
- Similarly, the universe has parts that function together for a purpose
- So the universe must have been designed by a universe maker
- The universe is a far more wonderful design than a watch, so its designer is much greater than any human designer
- The universe designer is God
Paley’s supporting examples for his analogical argument
Eyes - they are superbly adapted for vision, has the right arrangement to achieve its purpose of seeing
Fins and Gills - so fishes are perfectly adapted to live in water
Wings - with properly dense bones perfectly adapted to flight
Stars, planets and comets - with regularity in their orbits
Hume’s arguments against Paley’s - lesser being
Even if we grant that the universe was designed, there is no evidence that this was the God of Christian theism. A lesser being could’ve designed the universe / it could be a team of lesser beings
- intelligent minds usually have physical bodies, there is no obvious reason to suppose that the designer of this universe was a metaphysical being, it could’ve been mortal and died long ago
- design is normally from teamwork, there is no reason for the designer of the universe to be a single being, could be a team of lesser beings
Hume’s arguments against Paley’s - evil and suffering
Existence of evil and suffering suggests that there is a limited designer (referenced Epicurus’ questions about the existence of evil)
Inconsistent triad: God is omnipotent, God is omnibenevolent, evil exists
Hume suggests that the existence of evil makes it so the world might not be from a being of infinite power, wisdom and goodness - the universe could’ve been designed by an infant or a senile God
Hume’s comment on evil and suffering
“Is [God] willing to prevent evil, but not able? Then is he impotent.
Is he able, but not willing? Then he is malevolent
Is he both able and willing? Whence then is evil?
- Hume
Hume’s arguments against Paley’s - unsound analogies
Analogies between the way the universe works and the way machines work are unsound
The world may have grown themselves without the need for a designer
E.g. Darwin’s evolution theory
Hume’s arguments against Paley’s - anthropomorphism
By making an analogy comparing human designers to the designer of the universe seems anthropomorphic - we are trying to explain the universe in our own image
We have no experience or knowledge at designing a universe, by imagining God to be like a human designer would be anthropomorphic
Hume’s arguments against Paley’s - universe created by chance
The universe could have developed into a comparatively ordered state simply by chance
Hume’s ‘Epicurean Hypothesis’ — the basic constituents of the word were indivisible atoms, the world is no more or less than arranging atoms, therefore it was inevitable that the atoms would arrive to an ordered state
Weaknesses of Paley’s design argument - lesser beings as designers
Even if the universe was designed, the all-powerful God of Christian theism is a greater cause than is needed to account for that design
The universe could well have been produced by a team of lesser beings, or even by designers who ‘botched and bungled’ it
