Elements and Qualities

Natural Philosophy

Empedocles (490 BC to 430 BC)

The person credited with first theorizing that everything comes from air, water, earth and fire is Empedocles of Acragas. In the 5th century BCE, Empedocles wrote two works in verse: “On Nature” and “Purifications”. The complete poems did not survive intact. Scholars work with fragments of these poems and also references to the theory from other sources.

“Elements” is a term that wasn’t in use yet at the time of Empedocles. It was introduced later by Plato.

The verses of “On Nature” reference gods instead of the elements themselves and there is some debate about which god is which element, but it is agreed that the poem referred to air, water, earth and fire as the roots to everything. These roots are moved by two opposing forces, Love and Strife.

Twofold is what I shall say: for at one time they grew to be only one
Out of many, at another time again they separate to be many out of one.
And double is the birth of mortal things, double their death.
For the one is both born and destroyed by the coming together of all things,
While the other inversely, when they are separated, is nourished and flies apart.
And these incessantly exchange their places continually,
Sometimes by Love all coming together into one,
Sometimes again each one carried off by the hatred of Strife.

And inversely, the one separating again, they end up being many,
To that extent they become, and they do not have a steadfast lifetime;
But insofar as they incessantly exchange their places continually,
To that extent they always are, immobile in a circle.

The roots underlie everything. The poem goes on to say that they are equal, but each has their own character. It also says they dominate by turns as time goes on. So things do change as these roots come together and separate in different ways, but each time is “continually similar” because the roots are the same and unchanging.

Love pulls everything into one despite their different qualities. When roots combine together with other types of roots, they are not a pure expression of themselves anymore. They make something new together, but what they were alone is lost.

At an extreme domination of Love, the roots are completely intermingled and indistinguishable. They lose themselves in the One. This is also called the Sphere. It’s immobile and pulled together completely. Nothing can move.

Strife causes the roots to repel one another and be separate. The qualities of the roots can be distinguished and seen independently. When Strife dominates, the roots are separated and identifiable as air, water, earth and fire (or the gods he refers to in the poem). So, they are not separated due to their incompatible qualities, they are separated due to the force of Strife.

At an extreme domination of Strife, the world is destroyed in a Whirl. It is complete separation and activity. Nothing can come together.

The forces of Love and Strife wax and wane, always in contention. In the Stanford Encyclopedia entry about Stoicism, it says this about the elements:

The first things to develop from the conflagration are the elements. Of the four elements, the Stoics identify two as active (fire and air) and two as passive (water and earth). The active elements, or at least the principles of hot and cold, combine to form breath or pneuma. Pneuma, in turn, is the ‘sustaining cause’ of all existing bodies and guides the growth and development of animate bodies.

In this description, the Fire is Hot and the Air is Cold. They are the active elements, the breath that goes in and out. Water and Earth are the passive elements – the Wet and Dry.

In another reference, all of the elements of the material world were passive (fire, air, water earth). The active principle was the indestructible, ungenerated Logos.

In both cases, Stoic theory says that the material world of the four elements is destroyed and recreated on a continual basis.

Inward motion and coming together is like extreme cold. It’s solid and unmoving.
Outward motion is like extreme heat. It is separate and individual and moving all over the place. The outward motion makes the roots distinctive, with their own character and qualities.
Complete domination of either one is the end of life. During life, they constantly separate and come together and blend in different ways due to the forces of love and strife.

Elements attract and repel one another in different parts of the cycle. When the roots are separated into distinguishable elements and parts of our world, they arrange themselves in the following way:

the mass of earth is at the center; water more or less surrounds the earth. Air forms the next layer. From fire at the periphery, the sun comes to be as a distinct entity. This geocentric formation is what the ancients usually recognized to be our cosmos.

I can’t find more to link roots or elements to qualities, but Chris Brennan writes about in “Hellenistic Astrology: The Study of Fate and Fortune. The book summarizes the writings of 2nd century astrologer Valens as:

fire and air intermingle with each other since they rise upwards, and in the process of doing so, fire which is hot, is supported by the more mild temperature of the air, which is cold, while at the same time, air is warmed up by the heat of the fire, so it doesn’t become overly cold or frigid.
Similarly, Valens says, that the earth, which is dry, is nourished by the moisture of water, which allows the earth to make things grow, while water itself is born from and contained by the earth.

The idea is that the blending of the elements makes each more temperate, less extreme. The opposites complement each other and also move in the same direction.

It is interesting that these opposites in qualities are also the elements that are opposite signs on the zodiac wheel.
Fire is Hot
Air is Cold
Water is Wet
Earth is Dry

When we study the polarity of the opposite signs, there is a common theme but with two extremes. We can identify with one sign or the other, but when we see the need to work on this area, we generally look to the other side of the chart to try to figure out how to find balance. This matches with the ideas of temperance in ancient philosophy.

It wasn’t able to find more sources for this theory of the qualities of the elements, but I’ll keep looking.

Plato (427 BC to 328 BC)

Plato describes the Creation of the elements in “Timaeus”.

Now that which is created is of necessity corporeal, and also visible and tangible. And nothing is visible where there is no fire, or tangible which has no solidity, and nothing is solid without earth. Wherefore also God in the beginning of creation made the body of the universe to consist of fire and earth. But two things cannot be rightly put together without a third; there must be some bond of union between them. And the fairest bond is that which makes the most complete fusion of itself and the things which it combines; and proportion is best adapted to effect such a union. For whenever in any three numbers, whether cube or square, there is a mean, which is to the last term what the first term is to it; and again, when the mean is to the first term as the last term is to the mean-then the mean becoming first and last, and the first and last both becoming means, they will all of them of necessity come to be the same, and having become the same with one another will be all one. If the universal frame had been created a surface only and having no depth, a single mean would have sufficed to bind together itself and the other terms; but now, as the world must be solid, and solid bodies are always compacted not by one mean but by two, God placed water and air in the mean between fire and earth, and made them to have the same proportion so far as was possible (as fire is to air so is air to water, and as air is to water so is water to earth); and thus he bound and put together a visible and tangible heaven. And for these reasons, and out of such elements which are in number four, the body of the world was created, and it was harmonised by proportion, and therefore has the spirit of friendship; and having been reconciled to itself, it was indissoluble by the hand of any other than the framer.

This one sounds more complicated because Plato is bringing in mathematics and shapes, but it repeats the idea that Fire and light are the opposite of the solid Earth. He then uses math to say we need intermediaries to be able to bring these together in the 3D world of depth that we can see. Air and water are the intermediaries. We are also introduced to the relationships that connect them. The order is the same as the order in the Stoic theory description. (Fire => Air => Water => Earth)

After describing more of creation, Plato discusses the ways that the elements transform into one another.

In the first place, we see that what we just now called water, by condensation, I suppose, becomes stone and earth; and this same element, when melted and dispersed, passes into vapour and air. Air, again, when inflamed, becomes fire; and again fire, when condensed and extinguished, passes once more into the form of air; and once more, air, when collected and condensed, produces cloud and mist; and from these, when still more compressed, comes flowing water, and from water comes earth and stones once more; and thus generation appears to be transmitted from one to the other in a circle. Thus, then, as the several elements never present themselves in the same form, how can any one have the assurance to assert positively that any of them, whatever it may be, is one thing rather than another? No one can.

So, Plato describes a cycle of changing forms. It’s different from the Stoic idea. Empedocles’ roots did not transform – they were grouped together in various ways for different outcomes. But as philosophers applied this to nature and life itself, they saw transformation, so they tried to adapt the theories to account for this.

Transitions will be the core focus when Aristotle looks at these issues and his approach in all the subjects he tackles was very detail oriented.

Plato goes on to theorize about the universal nature and eternal beings. He also questions whether these elements are self-existent or if they need us to perceive them. Plato decides that the elements are bodies, which means that they are solid and must exist in planes. He then describes the shapes of the elements, some of which can change into the others. He states that the elements themselves don’t generate the other elements. Instead, the shapes separate and combine in different ways to produce the different forms of the elements that we see in the world.

Aristotle (384 BC to 322 BC)

The theory that seems most popular today comes from Aristotle. However, I think the structure of the polarities in the zodiac signs and the quote from Valens show that both philosophies were still part of the ecosystem as astrology was developed.

Aristotle was a pupil and colleague of Plato for 20 years, and he agreed with Plato about a lot of things, but not about Forms. Aristotle felt the idea of unchanging, everlasting Forms did not solve the problem of describing how things come to be and how they change. He was also critical of the ideas of the elements coming from Stoic philosophy for the same reason.

In “On Generation and Corruption”, Aristotle is focusing on the changes that we see in the world, different states of matter. If the elements are unchanging, how do things grow? How do they come to be? How do they pass away? At this time, there was debate on the number of elements, what the elements were and the mechanics of altering them (if they could be altered).

According to Aristotle, the issue is that he feels coming-to-be and passing-away is different from the change of a single element. He quotes Empedocles as saying: ‘There is no coming-to-be of anything, but only a mingling and a divorce of what has been mingled’.
But Aristotle rejects that idea.

To Aristotle, the elements are not eternal, unchanging and indivisible. In the world, elements change their characteristics and qualities. They change into one another, alter their qualities and transform. For example, when water turns to steam (air), Aristotle is saying that the water passes-away and the air comes-to-be. He is not satisfied with the explanation that qualities attach to the elements at some times and separate from them at other times (association and dissociation). He wants to define what happens when things change.

Aristotle introduces the idea of a substratum underlying everything and works on the theory that the elements change by acting on each other through the substratum. For this to work, the elements that make contact with one another will have an extreme quality in common.

As he works on this transition logic for complex substances like flesh and bone, he changed the opposites. Aristotle was thinking about the elements as they appear in the world. With that focus, Air can’t be Cold. Air is invisible and amorphous and moving. Water heated up and boiling creates steam and disappears into the Air.

When he is finished, they no longer match the sign polarities in the zodiac wheel.
Earth is opposite Air
Water is opposite Fire

Aristotle writes:

‘Hot’ is that which ‘associates’ things of the same kind (for ‘dissociating’, which people attribute to Fire as its function, is ‘associating’ things of the same class, since its effect is to eliminate what is foreign), while ‘cold’ is that which brings together, i.e. ‘associates’, homogeneous and heterogeneous things alike. And moist is that which, being readily adaptable in shape, is not determinable by any limit of its own: while ‘dry’ is that which is readily determinable by its own limit, but not readily adaptable in shape.

This is a slight departure because we think of Hot and Dry as separating and dissociating, while Cold and Wet bring things together or connects them. Extreme Cold was the solid mass.

Aristotle developed this as he tried to reduce down many qualities to their essence. Many of the adjectives he evaluated reduce to moist or dry because they either yield and adapt their shape or they are solid and dry and singular.

Aristotle theorized that these four elemental qualities can be combined with each other, forming 6 couples because none can be combined with its opposite. He then attaches the qualities to the elements, which he says are not simple bodies, but blended ones.

For Fire is hot and dry, whereas Air is hot and moist (Air being a sort of aqueous vapour); and Water is cold and moist, while Earth is cold and dry.

Later in the text, he assigns their primary quality.

for Fire and Air are forms of the body moving towards the ‘limit’, while Earth and Water are forms of the body which moves towards the ‘centre’. Fire and Earth, moreover, are extremes and purest: Water and Air, on the contrary are intermediates and more like blends. And, further, the members of either pair are contrary to those of the other, Water being contrary to Fire and Earth to Air; for the qualities constituting Water and Earth are contrary to those that constitute Fire and Air. Nevertheless, since they are four, each of them is characterized par excellence a single quality: Earth by dry rather than by cold, Water by cold rather than by moist, Air by moist rather than by hot, and Fire by hot rather than by dry.

So, here we have the following elemental qualities:

Fire is Hot and Dry, primarily Hot
Air is Hot and Wet, primarily Wet
Water is Cold and Wet, primarily Cold
Earth is Dry and Cold, primarily Dry

Aristotle’s elemental qualities are often shown by this diamond shape.

So, the philosophy shifted from what seems to be a simple and poetic idea from the Stoics to a more detailed and rigorous inquiry about transformation of the elements. In doing so, the conception of the elements and their primary qualities changed

Elements and Qualities

To summarize, the Earth is at the Center, most dense. Water also moves downward and surrounds the Earth
Fire is the lightest and highest. Air also moves upward and supports the Fire.

It seems like originally, there were two motions. It was like a breath, inward and mingled together (Cold and Wet) or outward and separated (Hot and Dry). Fire (Hot) and Earth (Dry) were most separated and extreme. Air (Cold) and Water (Wet) moderated the extremes.

As philosophers pondered the elements, the definitions were modified. Hot is still separated and active and Cold still brings things together. Wet becomes formless and adaptable. Dry holds a shape (as long as there is enough moisture there to adhere).

In all of these, Fire is Hot. It separates out what is foreign and eliminates it. It activates and energizes. The secondary quality of Fire is Dry. This seem sto go back to the earlier definition of separating things, rather than the new one of holding a shape.

Air was Cold in the earlier theory, but it became Hot and Wet, primarily Wet. It seems they wanted Air to be Hot because it is amorphous and separated. Wet is formless and adaptable and unlimited, which fits the qualities of Air.

Water was Wet in the earlier theory, but it became Cold and Wet, primarily Cold. Cold brings things together and combines them. Wet is formless and adaptable. Moisture connects things. Both of these qualities fit with Water.

In all of these, Earth is Dry. Seeing it as separation, I think an Earth with no moisture can be seen with desert sands or ashes or dust storms. Water moderates the Earth and makes it fertile. In the later theory, Earth holds its shape. It can be molded and is the solid ground the we walk on. The secondary quality of Earth is Cold. Cold brings things together. This can apply to the solid form of Earth.

Elemental theories have changed over time, especially as they were subjected to more analysis when they were considered part of science. Science has moved on from these ideas, but the earlier poetic verses still evoke something in me. Instead of focusing so intensely on changes, they invite us to contemplate the fundamentals of what is, to ponder the most basic nature of things.

Whichever appeals to you, these theories were a part of the conception of the meanings of the zodiac signs and the planets. Reflecting on these elements and qualities can deepen your understanding and enrich your interpretations.
