Chapter Twelve: The Design Argument: Cosmic Fine-Tuning
(pages 240-265)

Christianity teaches that the world has been created and designed by God. The universe itself shows evidence of this design. In this chapter, Groothuis first looks at the Christian account of design, noting that the Christian account makes sense of the appearance of design as well as the imperfections in the world. The author then looks at the method by which design is detected, explaining the "design filter" and how it applies to the fine-tuning of the universe for intelligent life.

After spending some time explaining the physics of fine-tuning, the author then deals with objections to the design argument from fine-tuning. These include the truism objection, the inscrutable odds objection, the chance, one universe hypothesis, the multiverse theory, and the more-fundamental-law objection.

Notable quotes:
This chapter and chapter fourteen claim that there is enough design evident at multiple levels of nature to infer that there is a Designer. However, there is also evidence of deformity, decay and disease, indicating that the design is often less than optimal. Thus there is enough evidence to believe in a Designer, but not enough to claim a perfect creation. There is enough deformity to warrant the idea of the fall, but not enough to deface the idea of design entirely. Hence, we have evidence for both creation and Fall in nature. (Christian Apologetics, p. 242) 
Those who reject all design explanations in principle have committed the logical fallacy of begging the question in favor of naturalism; if so, their naturalistic theories become unfalsifiable and impervious to counterevidence - traits that are hardly theoretical virtues in the philosophy of science(Christian Apologetics, p. 247)
But suppose a theory of everything were discovered that revealed one superduper natural law demonstrating that all that seems contingent is really physically necessary. Would this eliminate design as the best hypothesis for the resultant universe? No. The postulated natural law itself would be improbable and specified for life to exist. That is, it might have been otherwise(Christian Apologetics, p. 263)  
  1. Are there other objection to the fine-tuning argument that you have encountered?
  2. What are the strengths and weaknesses of using the fine-tuning argument?
