Preface
This article will deal with the ideology of positivism, rationalism and Karl Popper’s idea of good science. It will also further deal with why “Praying for person X made person X well from ailment Y” is not being a good form of science, but pseudoscience at best, particularly when presented in a scientific manner.
Definitions
Postivism is a scientific idelogy that we can only produce good science with the help of empirical data, most notably, by gathering facts. Is something not a fact, then we cannot consider it to be a positivist claim. So if I make a statement that the earth is flat when we have clearly observed that the earth isn’t, it is a false statement simply because it is not based on empirical evidence and because it is not a given fact. If I however say that the earth is round, it is a good positivt claim because we have good supoprting evidence that the earth is round and people have observed it as such, we can thus consider it a fact and the statement to be true.
Rationalism is a specific scientific ideology in turn developed by Karl Popper, stemming from the idea of positivism. Karl Popper’s goal with developing rationalism was to first of all debunk pseudoscience, secondly to set up a border when something can be considered good science and when it isn’t. Karl Popper defined good rationalist science as “finding faults in the problemsolving”* and “by speaking to thinking and experience rather than to moods and emotion”*.1
So the biggest difference between positivism and rationalism lies in that positivism does not necessarily change a theory when the empirical data does not fully support it, but may use help-theses, something Karl Popper despised. Rationalism then, is the complete reforming of a theory when new data is found, or when the theory is incapable of explaining the current data properly without using help-theses which are applied ad hoc.
The good positivist or rationalist science
Then how would positivist or rationalist science look like? A positivist would try to study the empirical data as good as possible and then make factual statements about those, a rationalist would look at the same empirical data but is more interested in being critical to how to explain the data and finding faults in this explanation while at the same time trying to appeal to logic and experience rather than that of emotion. This brings us to the main point, namely why praying, as evidence for the existence of god, is not evidence and why it is not scientific.
Example
One of the most common stories you hear from Christians as evidence for god is when they make a statement that praying works and they’ve seen it. Now, let’s assume ourselves in the role of a Christian practioneer who is praying for a relative being seriously ill, to the point where this illness is endangering this person’s life. As a good Christian, we are praying every day for this relative to become better, but the doctor’s treatment seems to be negative. Instead this person seems to become more ill than well. Suddenly though, there is a turn of events, without any seemingly explainable cause, the relative is cured from the illness and our conclusion must be that it was the work of god. Or wait, is it really?
A positivist would not accept this explaination, because obviously the empirical data has not been studied enough. The primary data here being our now cured relative, and why this relative all of sudden became better when it seemed that the medication made no difference. There are many factors to consider, such as our relative’s physiology. Maybe our relative really didn’t need any medication, because this person’s physiology worked in such a way that this person was supposed to overcome this illness regardless. Maybe the doctors gave this person the wrong medication. This cannot be outruled either. Doctors are human and humans make errors. The doctors gave our relative the wrong diagnosis and thus also the wrong treatment. A variant of the previous point, but happens all the time as well. A positivist would then start to debunk these theses by investigating the empirical data related to them, such as taking blood samples from the relative and studying them, or asking the doctors whether they changed the medication or if they believe they missdiagnosed the relative.
A rationalist would of course also do the above, but would be even more interested to see if we can trace any fault of logic in the original reasoning. It seems we can find quite a few of them. First of all, we cannot be certain god exists, as we have no evidence for this. Not necessarily using Occham’s Razor here, but a rationalist would examine the claim how probable it would be that god intervened and did so because of our prayers. Secondly, we also have the issue of prayers themselves. In the Bible it states that god knows everything, god is omniscient. Would it not be enough then to just think that we want to save our relative for god to respond to such a need? God would know even without having us praying, thus, it actually seems more logical that it was not the praying that was the actual cause. Thirdly though, and probably the greatest issue with this example is the emotional part of the argument. A religious person would of course want to believe it was god, it speaks that the religious person’s needs. It has thus an emotional appeal, rather than it being rational. So while a religious person may be overlooking some logical inconsistencies in their problemsolving when it comes to such statements as “My prayers saved my relative from dying”, the reason why they would believe such a statement is more because of the emotional appeal, they want it to be true, not necessarily because it is true. So when Christians make statements like these, they are not scientific in their approach, because they overlook great many faults in their reasoning.
