With the new year, we are starting a new series called, “What Naturalism Means to Me”. It is an opportunity for our readers, like you, to share what Naturalism means for you. We are looking for essays between 1000-3000 words. Send your submissions to humanisticpaganism[at]gmail[dot]com.
Naturalism is one of those words that wouldn’t need to exist if it were not for its opposite: supernaturalism. Originally, nature meant “the way something is” as in, “the nature of a cat” or “the nature of a car”. The natural sciences study “the way things are” or “the nature of existence”.
The natural universe is just as we see around us. It is, quite simply, what an animal or a child would assume by operating in their environment – without any ‘high-minded philosophy’. Looking closer, it appears to be a vast tapestry of matter and energy, moving and interacting through space and time.
This tapestry is an ever-changing, impermanent, and interdependent network which has at least two major traits worth noting here: monism and natural law. These two traits connect directly to the relevance of evidence and reason respectively, for those who would navigate within it.
Monism and Evidence
Without getting too technical, there are varieties of ‘monism’. But simply put, naturalists view the universe as one integrated whole. The parts of this network are interconnected and interdependent, with nothing ‘transcending’ or ‘super’ to nature that we can see. So, it’s not that things outside Nature aren’t possible – it’s just that we simply don’t base our perspectives, principles, or practices on them.
The reason why our use of evidence is derived from interdependence is because this creates a chain of consequences for every state of being or event in a system. In other words, if something is true, or an event happens, it leaves behind results of that happening or states which might be observed and traced back through this network to its cause. Anything outside this interconnected web in which we find ourselves would not leave evidence that we could reliably use to make statements about it. So, the reason we do not include such things in our views is not necessarily because reality is limited, but because we are limited.
Natural Law and Reason
Natural Law, or the laws of physics, are really quite an astounding thing to consider. Heraclitus spoke of the Logos – that is, the underlying rational order by which the universe operates, and he said Nature’s complex transformations were like a kindling in an ever-living divine fire. Some later thinkers would associate the rational operation of the universe with a reasoning mind like ours, which played into concepts of personified deities (eventually the Christians used ‘Logos’ to mean ‘the word of God’). But it is clear to us today that the universe does operate rationally, in that its motions can be examined, understood, and described in rational ways by reasoning minds.
Buddhist causality (see pratityasamutpada or dependent origination) also describes how events take place in the world because of prior causes. This may seem a rudimentary statement to us today, but in ancient times when so much was not understood about nature, this was an impressive and crucial achievement. People didn’t need to fear that a storm or illness was because they were displeasing the gods or spirits. Neither did people need to think that their lot was entirely up to chance.
The fact that things happen for a reason and because of causes means that we can work to understand those causes and take action to change them. Centuries before the beginning of the Enlightenment, these concepts would open the door to the use of reason to solve problems. This is why our use of reason derives from the fact that the universe operates in predictable, understandable ways.
When people talk about the supernatural, what they are proposing are other network which has some other kind of substance, causality, or rules. It is often described as being a superset within which nature is contained. Such a realm, by definition, would be a dualistic model where the causality links flowing between them would be cut off. This would mean such claims are inherently unapproachable or unverifiable by reason and evidence. We could never make a claims (for or against) such a thing while keeping strictly to a naturalistic approach to knowledge.
However, within these alleged models, there are said to be ways the supernatural realm can pierce into this one which, from the point of view of the natural universe, would create effects without (natural) causes. These are the visitations, revelations, miracles, etc. These claims are different from the basic claim of the mere existence of some kind of supernatural realm or phenomena. In this claim such intrusions should indeed leave natural evidence that can be investigated. Many people have rigorously investigated all manner of these kinds of claims for centuries and there has yet to be a single piece of evidence that meets scientific standards which shows any supernatural claim to be true.
When supernatualists say “absence of evidence is not evidence of absence” they are absolutely correct in strict logical terms. There could always be some supernatural phenomena which doesn’t leave evidence or for which evidence simply hasn’t been found. While there are often claims that the supernatural can pierce into the natural realm, there doesn’t seem to be a reliably repeatable and testable means (even claimed) for the natural to pierce into the supernatural realm. This means that all such alleged miracles are spontaneous and unpredictable events of a kind that would be difficult to prove even were they purely natural happenings. For example, some entity offering a demonstration to one or a few people and then never heard from again.
Yet, the mere possibility of a thing does not make it rational to assume the actuality of a thing. There are many possible stories that can fit a few facts and many of them contradict one another. Therefore, naturalists choose to take the humble path and not make claims that cannot be backed by physical evidence. What’s more, Occam’s Razor demands that the explanation with the fewest assumptions are preferred, and this means that extraordinary claims (with many assumptions) require extraordinary evidence. While supernaturalists may quibble over the idea that no evidence exists for the supernatural, they certainly cannot claim that extraordinary evidence exists for it – otherwise there would be little debate. And, for a claim that questions the very foundations of reality and proposes whole new systems beyond the natural observable universe, extraordinary evidence is what should be required by any reasonable mind.
We cannot know that all the claims of supernaturalists are false, but we don’t need to know that to be naturalists. What we do know, as certainly as any human can know something, is that the claims are not rational to make.
Fortunately, a purely naturalistic worldview need not be nihilistic or meaningless. We have found ourselves in a vast and amazing cosmos full of more wonders than we can hope to fully access in our lifetimes. We have incredible tools of understanding and appreciation for these wonders. And, most of all, we have one another – the possibility of loving our fellow human beings and meeting the challenge to help make the world a better place. We are the meaning-makers and, as Carl Sagan said, a way for the cosmos to know itself.
Those who are also Spiritual Naturalists look to practices which cultivate within themselves qualities which aim to expand their awareness beyond small egotistical concerns, toward this kind of larger cosmic perspective. We take on awareness of the limitations and imperfections of knowledge as a spiritual practice of humility in making claims. We choose to focus instead on compassion, kindness, mindfulness, and understanding for all. And, to the degree we do this, we find the sting of mortality less and less potent; in its place: greater joy and peace.
With love and thanks,
