I recently came across this article in Breitbart.com which describes how recent studies have shown that those who attend religious services regularly are happier than those who don't. Interestingly the study, as far as I can tell from the article, indicates that the practice of the religious aspects of the faith ie attending church, are critical. It is not just what you believe that is important, but also the practice of the faith and more than anything else the regular attendance at services as a contributory factor to happiness, as measured in this study. (I always wonder whether if these studies have any value, I must admit, wondering how accurately you can measure happiness, but for argument's sake, I will take the results at face value here.) The article, presumably reflecting thoughts of the scientists who made the study, goes on to the consideration of why people are happier if the go to services regularly and admitted they found it puzzling. They hypothesized about whether or not it is the fact that those who attend religious services are more likely to be involved in the community and so the additional social support makes people happier. But then point out that that this doesn't seem to be the reason because they found that those people with a similar level of community involvement reported lower levels of happiness if they did not attend religious services as well.
I haven't read the full study, only the newspaper article about it, so there may be aspects of this study missing, but based upon what I read, this is what is interesting to me about the analysis. There appears to be an assumption that the explanation must relate to the impact of human relationships. There appears to be no consideration of the possibility that what the religions themselves might have to say about why people are happier, is true. That is, that God exists and if we worship Him we are happier. Always, it seems, it is assumed that he doesn't and the explanation must be psychological.
There is an alternative hypothesis, that is probably the one the scientists would have been given if they had asked any one of the thousands whom they observed going to the religious ceremonies under consideration. That is that there is truth in what they believe about God. The religious ceremony is part of the expression of a relationship with God, and it is the flourishing of that relationship which causes greater happiness.
For Catholics, I suggest, it should be no surprise that this is what the study showed (other things being equal) for the Church says that the worship of God is 'summit'' of human life. In other words, the purpose of human existence, to which all other activities and goal ultimately conform if we want to be happy, is the worship of God. At first glance, this research is consistent with the idea.
There may well be many other possible psychological reasons for the survey results and the properly scientific approach is to consider each one and investigate it. Anyone who is genuinely interested in the search for truth would have to consider, at least, in addition those hypotheses that rest upon an assumption that there is a God, just as much as those that rest upon an assumption that there isn't.
The difficulty with the God-hypothesis, if I can call it that, is that it is beyond the realm of what natural science can investigate. As soon we enter into consideration of that which is “beyond the physical” (from Greek we use for this the term “metaphysical”), we move out of the realm of physics and into that of philosophy as the word is used today. (In the past natural science would have just been a subdivision of philosophy). This causes problems for many. To acknowledge the possibility of a realm of existence beyond the physical challenges a dogma of the modern age - scientism. Scientism is a philosophical viewpoint held by many people in the West, which says that only that which can be proved by natural science is true. That is, if you can’t prove it scientifically, it isn’t true. This philosophical viewpoint is not in itself scientifically provable, it is just an assumption, and so contains within it the logical contradiction that disproves it.
The other point that many, even scientists, do not know is that natural science can never prove the existence of God. Because of the underlying assumptions behind the scientific method - especially that it is investigating only those things that obey the natural order - natural science can neither prove nor disprove the existence of God who by definition is not bound by the natural order. It cannot speak on the subject at all. Science assumes that the whole universe conforms to this order and does not take into account any other form of existence.
This is not to disparage the value of science, rather just to be aware of its limits. I for one am very glad that the scientific method, based upon these limiting assumptions, we developed. For this is part of what opened up the natural world to the great advances in science; and I enjoy the fruits of modern science in almost every area of my everyday life. Science, as we understand the term today, is a good thing. However, this will only be so provided that we are aware of the limitations that the assumptions that underlie the scientific method place on it's power as a tool for investigating truth; and do not depend on it to help us in areas that are beyond its scope.
