The relationship between science and religion: Turfs of Aristotelian causality
Posted by: Waldheri in Philosophy, Religion, tags: aristotle, descartes, epistemology, Philosophy, Religion, Science, TheismAristotle was one of the first philosophers to really try and tackle the field of causality. In Metaphysics, Aristotle proposes four different causes. These are the causa materialis, the material cause; causa formalis, the formal cause; causa efficiens, the efficient cause and the causa finalis, the final cause. For this essay, it is not important to go into the first two. Also note that our current, every-day use of the word “cause” is only one of these four, namely the efficient cause, which denotes the agent that brings something about. If A necessarily leads to B, A is the efficient cause of B. The remaining cause which is of importance in this essay is the final cause, which denotes the purpose or intended end of a certain action. If A is a necessary step to achieve B, B is the final cause for A.
It may be apparent that these causes are different, yet related. The most important aspect is the directionality these causes imply. It is this directional property that I will be focusing on a lot. One could say that the efficient cause looks from the past towards the present, whereas the final cause looks from the present towards the future. You could say that the efficient cause is the answer to the question “how”, and that the final cause is the answer to the question “why”. Another important aspect in which these two causes are different is intentionality. In case of the efficient cause, no goal is necessarily implied, whereas in the case of the final cause there is. A conscious entity is required for a final cause, as actions result from being a necessary step towards a goal.
Having said that, I assume bells have already started ringing. This description of two particular Aristotelian categories of causality will remind many of how the relationship between science and religion is often perceived: science answers the “how” questions whilst religions answers the “why” questions. In other words: science provides efficient causes, whilst religion provides final causes. The way science provides these answers is through the scientific inquiry: a method applied to a domain in which causal homogeneity and methodological naturalism are assumed. Therefore we find a directionality from past to future in science, as well as an absence of intentionality. This is why God can never scientifically be said to be a cause of anything, because an agent with a mind does not necessarily behave the same way the next time (this is also why creationism is inherently unscientific). Science is constrained, but progressive; assuming that the accumulation of information is higher than the loss of data, and assuming that there are people with novel ideas once in a while, we can expect more accurate models of reality emerge from science over time. In other words: For more accuracy, look later in the scientific archives.
Religion is different; as it (though not exclusively) provides answers to questions concerning final causes. The idea that religion is closely connected to this category of cause are supported by often invoked sayings such as “God has a plan for us all” or “God works in mysterious ways”; but also by concepts of “the greater good” and “God’s will”. The intentions of a deity for the future are the most important factor for providing an answer to the “why” of the events that occur in the present. Therefore we find a directionality from future to present in religion, as well as a clear presence of intentionality. The method that religion uses for discerning the answers it provides are wholly contingent upon interpretation of the “revealed truths” contained within “sacred books”. This means there is no epistemological basis for answers stemming from religions: they are wholly contingent upon an assumption of authority. Unlike science, religion is not progressive, but static. The prevailing method for one who wants to analyse religious answers is to look at the original texts. The earliest manuscripts are more authoritative than later ones, because these might contain alterations introduced by scribes. In other words: For more accuracy, look earlier in the religious archives.
There is also something else going on, because religious answers do not have to be constrained. Ideas spawned from religion do not even have to be consistent with logic. Such examples are abundant in theistic religions. Take for example the position of Descartes about the omnipotence paradox (“Can God create a rock which He cannot lift?”): he posits that God has absolute omnipotence, being above logic and able to do even that which is logically self-contradictory. The other attributes the Abrahamic god is often accredited with also result in logical paradoxes. These are the coexistence of God’s omniscience and free will, and the problem of evil (the coexistence of God’s omnibenevolence and suffering). Luckily, not all theologians are as drunk on God as Descartes was. They acknowledge logic as a constraint on God, as well as on the answers religion provide. As such, there exists room for debate, which is wholly absent with those who side with Descartes.
One has to wonder, though: if God is constrained by logic, is he then not also constrained by the natural laws that humans discovered through the application of logic and the epistemological toolbox we call the scientific method? And if that is so, why not recognize the basis to religious answers is logically fallacious to start with? This is one of the important questions in examining the relationship between religion and science. Though both give answers to different Aristotelian causes in principle, religion often moves beyond it’s turf. This may be evident in religiously inspired pseudo-science, such as creationism; but also in writings by philosophers who drank the God poison. On the other hand, science has been conquering land from religion on the battlefield of ideas. Questions that were previously unanswerable by science were answered by religion. In the light of the ever-improving scientific models of reality, ancient religious doctrine is approaching the absurd. Where the constrained light of science does not shine, religion stands rooted in it’s usual method: mere guesswork.
