 Cory Juhl (2006) argues along independent lines that we should not regard fine-tuning for life as calling for a response. According to Juhl, forms of life are plausibly “causally ramified” in that they “causally depend, for [their] existence, on a large and diverse collection of logically independent facts” (2006: 271). He argues that one would expect “causally ramified” phenomena to depend sensitively on the values of potentially relevant parameters such as, in the case of life, the values of the constants and boundary conditions. According to him, fine-tuning for life therefore does not require “exotic explanations involving super-Beings or super-universes” (2006: 273).
