He addresses the "who designed the designer" question.
Richard Dawkins was criticizing the design argument for God.He asked if the universe is designed,then who designed the designer(GOD).But Craig shows that in no-way does the question make the argument fail.Its simply a question out of the blues.Consider the premises of the argument below:
- The fine-tuning of the universe is due to either physical necessity, chance, or design.
- It is not due to physical necessity or chance.
- Therefore, it is due to design.
Craig says that we do not need to have an explanation for the explanation.If X is the best explanation for Y,we don't need an explanation for X.
The lack of an explanation for X does not negate the fact that X is still the best explanation for Y.
A good example would be,if you found a book on the beach and you exclaimed"this book must have been written by a writer".then your friend quips in and says," that cannot be,then who created/designed the writer?".
The origins of the writer are a non-issue as regarding the best explanations for the source of the book.As long as you agree that the book was written by a writer,then the lack of explanation of where the writer originated from does not negate the fact that the book was written by a writer.
In short if we needed to have an explanation for the explanation of everything in the universe,then we would never be able to explain anything.
