I don't recall what led to our discussion, but the other day at breakfast my wife Lydia mentioned in passing how her almost life-long freedom from belief in a supernatural being had always given her a sense of freedom. But instead of using the term "supernatural", she accidentally said "unnatural". We both laughed at this linguistic lapse. However, we got to thinking that perhaps when it comes to religious faith there's not that much of a distinction between those two words after all.
For what could be more unnatural than belief in a supernatural entity for which there is no proof of existence, or in an imaginary spirit world and the return of the dead to life? What could be more unnatural than perpetuating these superstitions and myths from generation to generation and by doing so hinder the progress of humankind's enlightenment and development? What could be more unnatural than killing and maiming and destroying property and resources in the name and at the behest of a fabled supreme being?
In short, isn't atheism then the most natural and rational mindset? Isn't accepting the universe on its own terms more realistic than trying to change it by fruitlessly praying for miracles? Isn't attempting to achieve a deeper understanding of nature through scientific inquiry more natural for adults than childishly making up stories to explain what we don't understand?
I hope that Lydia (or I) will make more slips of the tongue like the above. In doing so, who knows what other connections we'll uncover in the pursuit of knowledge and awareness?
