Let’s start with a simple fact: currently over 50% of the world’s population professes a belief in one of the 3 great monotheistic religions: Judaism, Christianity, or Islam. The monotheists are almost all either Christians (33%) or Muslims (22%). Adherents to Judaism make up less than one-half of one percent of the world’s population. Why is this so?
The vitality of monotheistic faith as a “mind virus” - a set of ideas very apt to “infect” any exposed minds - is indisputable. However, unlike Christianity or Islam, Judaism is not a proselytizing faith. This tends to limit its success as a mind virus. Christianity and Islam, on the other hand, are proselytizing, multi-ethnic faiths. When a monotheistic faith becomes proselytizing, watch out! Combine the vitality of monotheistic belief with the proselytizing compulsion, and you have a very infectious mind virus indeed.
In a sense, Christianity is Judaism, version 2.0. To the successful features of Judaism, like monotheism, Christianity has added the all-important compulsion to proselytize, while jettisoning tenets that are self-hobbling to a mind virus, such as the belief that the Jewish race are God’s “chosen people”. Also in Christianity there is a more full and hopeful vision of the afterlife, which adds to the appeal of the religion. Of course, Christianity comes with its own set of baggage, in particular, the notion that Jesus Christ, is, in fact, God, along with the concomitant mysteries of the Trinity, and of the “three persons” of the Godhead: Father, Son, and Holy Ghost.
Enter Islam, which is Judaism, version 3.0. Gone is the divinity of the Christ, a notion that was apparently too much for the desert peoples to swallow. But Christ remains a prophet, and his moral teachings remain intact. Another improvement over Christianity is that in Islam, God is depicted in an altogether less anthropomorphic way. In this respect, Islam is more intellectually respectable than Christianity.
It is often said that Islam is the world’s fastest growing religion. If that is so, the above considerations suggest a reason why: Islam is simply a more infectious mind virus than either Judaism or Christianity. It has all the monotheistic zeal of Judeo-Christian religion, but none of the baggage of Christian notions of divinity, or Jewish ethno-centricity. And because Islam is a more infectious mind virus than Christianity or Judaism, it is a more advanced mind virus than Christianity or Judaism. After all, what is the purpose of a virus, if not to infect?
What about atheism, considered as a mind virus? I’m afraid it has some rather distinct disadvantages in this regard. First of all, atheism lacks the proselytizing zeal of either Christianity or Islam. Most atheists are quite content with having saved themselves from religious belief, and are not too concerned with “saving” others. Neither does atheism offer comforting visions of the afterlife. Finally, atheism offers no easy answers to the basic questions of human life: ethics, the “meaning of life”, and so on. Note that I didn’t say it offered no answers, only no easy answers. All these factors tend to make the atheistic outlook a much weaker mind virus than almost any religious worldview.
Atheism does have a crucial saving grace, however: all the evidence says that it’s probably closer to the truth than any of the established religions. Understood properly, atheism is not a mind virus at all. Rather, it’s the state of not being infected. And that’s a good state to be in.
