The first major reason why people don’t believe in God is the problem of pain. The most commonly asked question in regards to this is “how could a loving God allow suffering?” or “why do bad things happen to good people?” Perhaps one of the best argument for this viewpoint is by philosopher J. L. Mackie. In his book The Miracle of Theism(Oxford, 1982) he says if a good and powerful God exists, he would not allow pointless evil. But because there is so much unjustifiable and therefore pointless evil prevalant on the earth, the good and powerful God simply cannot exist. His reasoning allows that a God may in fact exist, but it cannot be both all-loving and all-powerful at the same time.
Another argument against the belief in God is largely scientific. It holds that the belief in God requires a belief in an un-scientific, un-provable miraculous entity. Popular Atheist author and speaker Richard Dawkins famously said, “Although Atheism may have been logically tenable before Darwin, Darwin made it possible to be an intellectually fulfilled Atheist.” (The Blind Watchmaker, W.W. Norton, 1986, p.6) In his smash hit The God Delusion, Dawkins points to a statistic from 1998 that states only 7 percent of scientists in the National Academy of Science believe in a God. (The God Delusion, Boston: Houghton Mifflin, 2006. p.100) A big problem science and rational minded thinkers have with world religions and the idea of “God” is stories of miracles and supernatural occurences. Beginning in the Enlightenment period, many scientists looked at religious books like the Bible, and reasoned that anything that could not be measured or studied rationally or with the scientific method could not have happened. This thought is deeply rooted in the assumption that everything that is real can be studied in a rational manner.
I researched and found a couple responses by Theists to my first point (the problem of suffering) Although Mackie’s reasoning seems airtight, there lies within it a few major assumptions. One such assertion hidden in the reasoning is a fallacious definition of “pointless” or “unjustifiable” evil. Just because it seems pointless to us, does not mean it must be utterly pointless in reality. The statement also implies that just because a possible all-loving and all-powerful God allows something bad happen that we do not understand, or that we see no redemptive reason for, that does not mean there isn’t one out there. This reasoning relies enormously on our own cognitive abilities to wholly understand good and evil on a worldwide scale. That requires a lot of faith in oneself.
Equally as problematic, a great many attribute positive personal change to pain and suffering in their lives. It is said that suffering through trials produces perseverance and character. Author and philosopher C.S. Lewis said this in his book Mere Christianity:
“My argument against God was that the universe seemed so cruel and unjust. But how had I got this idea of “just” and “unjust”? What was I comparing this universe with when I was calling it unjust? Of course I could have given up my idea of justice by saying it was nothing but a private idea of my own,. But if I did that, my argument against God collapsed too – for the argument depended on saying that the world was really unjust, not simply that it did not happen to please my private fantasies. Consequently Atheism turns out to be too simple.” (Mere Christianity, Macmillan, 1960, p.31)
To take it even further, some who believe in God argue that the very presence and existence of pain and suffering proves His existence! Take philosopher Alvin Plantinga for example:
“Could there really be any such thing as horrifying wickedness? I don’t see how. There can be such a thing only if there is a way that rational creatures are supposed to live, are obliged to live.. A secular way of looking at the world has no place for genuine and appalling wickedness. Accordingly, if you think there really is such a thing as horrifying wickedness, and not just an illusion of some sort, then you have a powerful argument for the existence of God. (“A Christian Life Party Lived” Philosophers who belive. ed. Kelly James Clark. IVP, 1993. p.72)
An objection I found in regards to my second point (lack of scientific and rational proof for God) there are a few points made that might not hold water. Although the arguments sound good, science itself proves the opposite. Ever since the advent of modern science, we are discovering more and more that we never knew before, and equally cannot explain. Something like the occurrence of special types of hydrogen bonds that appear exclusively in water molecules or the events leading up the Big Bang are things that science, no matter how advanced or evolved it becomes, might never be able to tell us. This reveals that fallacy that because we cannot study or learn about something through a rational or scientific lens, it must not be possible to learn about at all. The crux of the argument once again relies on one’s own cognitive ability to be able to understand everything under (and beyond) the sun.
