I always like to point out to people that there are many famous atheists in every profession. To demonstrate that fact, I have prepared a short list of classical composers, many of whom were obliged to create religious music simply to pay their bills, yet they were sincere atheists. Why are there so many atheist composers?
You might expect scientists to be atheists because they haven’t found any proof that there is a God. However, I think many “creative types” may be predisposed to atheism as well. This is pure speculation on my part (or possibly the ramblings of an idiot savant). I think the creative process allows the mind to explore all possibilities – including the denial of the existence of a supernatural being. Once accomplished, that denial sure eliminates a ton of spiritual baggage.
I have included several modern atheist composers as well, just to see if you can find them in the list.
Franz Peter Schubert
Peter Ilyich Tchaikovsky
(yes, he was a serious composer of modern classical music)
