Abstract

This paper provides an empirical study of how religious belief influences the views of philosophers about natural theological arguments. Philosophers rated eight arguments for and eight arguments against theism. We find a correlation between religious belief and the perceived strength of arguments: atheists tend to find arguments against theism stronger and arguments for theism weaker; theists evaluate arguments for theism as stronger than arguments against theism. The assessments of agnostics fall between those of theists and atheists. Other factors that correlate with the perceived strength of the arguments are philosophical specialization and gender. We examine the potential role of confirmation bias, early-developed intuitions, philosophical expertise and gender differences to explain our findings.
