Appeal to nature - From Wikipedia, the free encyclopedia

Appeal to nature

From Wikipedia, the free encyclopedia
Jump to navigationJump to search
An appeal to nature is an argument or rhetorical tactic in which it is proposed that "a thing is good because it is 'natural', or bad because it is 'unnatural'".[1] It can be a bad argument, because the implicit (unstated) primary premise "What is natural is good" typically is irrelevant, having no cogent meaning in practice, or is an opinion instead of a fact. In some philosophical frameworks where natural and good are clearly defined in a specific context, the appeal to nature might be valid and cogent.


General form of this type of argument:
That which is natural, is good.
N is natural.
Therefore, N is good or right.

That which is unnatural, is bad or wrong.
U is unnatural.
Therefore, U is bad or wrong.[2]
In some contexts, the use of the terms of "nature" and "natural" can be vague, leading to unintended associations with other concepts. The word "natural" can also be a loaded term – much like the word "normal", in some contexts, it can carry an implicit value judgement. An appeal to nature would thus beg the question, because the conclusion is entailed by the premise.[2]
Opinions differ regarding appeal to nature in rational argument. Sometimes, it can be taken as a rule of thumb that admits some exceptions, but nonetheless proves to be of use in one or more specific topics, (or in general). As a rule of thumb, natural or unnatural facts provide presumptively reliable good or bad valuesbarring evidence to the contrary. Failure to consider such evidence commits a fallacy of accident under this view.[2][3]
Julian Baggini explains that "Even if we can agree that some things are natural and some are not, what follows from this? The answer is: nothing. There is no factual reason to suppose that what is natural is good (or at least better) and what is unnatural is bad (or at least worse)."[4]


The meaning and importance of various understandings and concepts of "nature" has been a persistent topic of discussion historically in both science and philosophy. In Ancient Greece, "the laws of nature were regarded not [simply] as generalized descriptions of what actually happens in the natural world… but rather as norms that people ought to follow… Thus the appeal to nature tended to mean an appeal to the nature of man treated as a source for norms of conduct. To Greeks this… represented a conscious probing and exploration into an area wherein, according to their whole tradition of thought, lay the true source for norms of conduct."[5]
In modern times, philosophers have challenged the notion that human beings' status as natural beings should determine or dictate their normative being. For example, Rousseau famously suggested that "We do not know what our nature permits us to be."[6] More recently, Nikolas Kompridis has applied Rousseau's axiom to debates about genetic intervention (or other kinds of intervention) into the biological basis of human life, writing:
[T]here is a domain of human freedom not dictated by our biological nature, but [this] is somewhat unnerving because it leaves uncomfortably open what kind of beings human beings could become… Put another way: What are we prepared to permit our nature to be? And on what basis should we give our permission?
Kompridis writes that the naturalistic view of living things, articulated by one scientist as that of "machines whose components are biochemicals"[7] (Rodney Brooks), threatens to make a single normative understanding of human being the only possible understanding. He writes, "When we regard ourselves as 'machines whose components are biochemicals,' we not only presume to know what our nature permits us to be, but also that this knowledge permits us to answer the question of what is to become of us… This is not a question we were meant to answer, but, rather, a question to which we must remain answerable."[8]

Some popular examples of the appeal to nature can be found on labels and advertisements for food, clothing, and alternative herbal remedies.[4] Labels may use the phrase "all-natural", to imply that products are environmentally friendlyand safe. However, whether or not a product is "natural" is irrelevant, in itself, in determining its safety or effectiveness.[4][9]Some compounds found in nature are for example powerful poisons.
It is also common practice for medicine to be brought up as an appeal to nature, stating that medicine is unnatural, and therefore should not be used. This extends to practices such as vaccination. [10]
