The quickest way to get from a high floor to the street is to jump out a window, but our “faith” in the laws of gravity and the fragility of our bodies make this an irrational act for anyone who cares to stay alive. On the other hand, an atheist gets along quite well, thank you, without believing in God. It only obscures the nature of faith to liken it to the inescapable necessity of believing in causal laws.
