Fear of Nature
Biophobia
Biophobia is a dictionary word for an aversion to nature, and the interesting thing about it is that the main hypothesis in the field treats a fear of nature as evidence for an attachment to it. It has no clinical literature of its own, and the arguments conducted under the name belong to environmental thought, education and architecture.
What the word actually says
Wiktionary gives the whole of it in three words: aversion to nature. The construction is bio- plus -phobia, and the same entry records that it is a piecewise doublet of zoophobia, the word this catalogue files as a fear of animals. One takes life and the other takes the animal, and they are built from roots that mean nearly the same thing.
No diagnostic manual carries biophobia. Nobody has published a case under it, no prevalence has been measured, and the reference literature on phobias does not run an entry for it. What it has instead is a role in an argument, and the argument is about whether human beings are built to like living things.
Why a fear of nature supports biophilia
The biophilia hypothesis, named by Erich Fromm and developed by E. O. Wilson, holds that people are drawn to living systems by their biology. Wilson's formulation is that biophilia describes the connections human beings subconsciously seek with the rest of life. The evolutionary version of the claim is that ancestors with stronger connections to the natural world held an advantage in knowing where food, water and shelter were.
The part that concerns this entry is a single line in the hypothesis. Affiliations toward natural objects count as evidence for biophilia whether they are positive or negative, and phobic reactions are named among the negative ones. What matters, in that framing, is that the reaction to a natural object differs from the reaction to a manufactured one. A fear of nature is not the opposite of a love of it, but a second proof of the same wiring.
This catalogue is full of the examples that argument runs on. The fears with the deepest histories and the widest distributions attach to living things and natural events rather than to the objects people actually get hurt by:
- snakes and spiders, the two standing exhibits in every account of prepared fear
- thunder, deep water, heights and the dark
- forests, as a place rather than as a thing inside one
None of them are power tools, traffic or electrical sockets, which injure far more people and have produced almost no named fears at all.
Where the fear of nature became a design problem
The other place the word does work is architecture, where biophilia was turned into a specification. Fractal fluency, a neuroscience model, proposes that human visual systems adapted to nature's repeating patterns and process them with unusual ease, and that patterns with a fractal dimension between 1.3 and 1.5 reduce physiological stress and improve cognitive performance when people look at them.
Biophilic design takes that finding and builds the patterns into rooms, on the reasoning that people now spend 92 per cent of their time indoors and away from natural scenery. The Fractal Chapel at the state hospital in Graz is one of the built examples. Whatever else that is, it is an admission that a species said to love nature has arranged its life so as not to meet any.
Why biophobia and ecophobia are not the same word
The neighbouring term is ecophobia, and its history has made it the more useful of the two. George F. Will coined it in the Chicago Sun-Times on 18 September 1988 to name the fear that the planet is increasingly inhospitable. Simon C. Estok then turned the 1988 coinage around: in his hands ecophobia is the fear of, or the ethical undervaluing of, the natural environment that produces cataclysmic environmental change.
Estok's version is where the two terms overlap, because his spectrum runs from fear through contempt and indifference to simple lack of mindfulness. That covers most of what biophobia would mean if anybody used it seriously. The difference is the accusation. Ecophobia, as Estok uses it, names a disposition that damages the planet, and biophobia names only a reaction to it.
David Sobel uses ecophobia for something closer to what a child feels: a helpless sense of dread about the future, produced by oil spills and deforestation rather than by the natural world itself. Three writers, one word, and the object moves each time. Biophobia stays where the dictionary left it, meaning an aversion to nature and nothing more precise than that.
Told apart
Often confused with Fear of Nature
- Fear of Environmental CatastropheEstok's definition of ecophobia covers contempt and indifference toward the natural environment, which overlaps directly with biophobia while carrying an accusation the other term does not.
- Fear of AnimalsWiktionary records biophobia as a piecewise doublet of zoophobia. The roots differ, the meanings barely do, and only one of the two words has ever been used in a clinic.
- Fear of ForestsHylophobia attaches to a place, and biophobia to living systems in general. A fear of the woods is the version of this that people actually report.
Common questions
Questions about Biophobia
- Has biophobia been studied clinically?
- No. It is a dictionary word: Wiktionary defines it as an aversion to nature and the reference works on phobias do not carry it. Where it appears in print, it is being used as the counterpart to biophilia in an argument about human evolution, not as a description of a patient.
- How can a fear of nature support the biophilia hypothesis?
- Because the hypothesis is about the strength of the reaction rather than its direction. Affiliations toward natural objects count as evidence whether they are positive or negative, phobic reactions included, and what matters is that natural objects produce a stronger response than manufactured ones do.
- Is biophobia the same as ecophobia?
- They overlap in Simon C. Estok's usage, which runs from fear through contempt and indifference to a simple lack of mindfulness. Ecophobia in that sense carries an accusation the other word does not.
- What does biophilic design have to do with it?
- It is the practical answer to the problem the word points at. Fractal fluency holds that human vision adapted to nature's repeating patterns and processes them with unusual ease, and that patterns with a fractal dimension between 1.3 and 1.5 lower physiological stress and improve cognitive performance. Architects build those patterns into interiors on the reasoning that people now spend 92 per cent of their time indoors and away from natural scenery, and the Fractal Chapel at the state hospital in Graz is one of the built examples.
