Four (Or So) New Fine-Tuning Arguments

Abstract

Both proponents and opponents of the argument for the deliberate fine-tuning, by an intelligent agent, of the fundamental constants of the universe have accepted certain assumptions about how the argument will go. These include both treating the fine-tuning of the constants as constitutive of the nature of the universe itself and conditioning on the fact that the constants actually do fall into the life-permitting range, rather than on the narrowness of the range. It is also generally assumed that the fine-tuning argument should precede biological arguments for design from, e.g., the origin of life. I suggest four new arguments, two of which are different orderings of the same data. Each of these abandons one or more of the common assumptions about how the fine-tuning argument should go, and they provide new possibilities for answering or avoiding objections to the fine-tuning argument.
