[Verse 1]

This most beautiful system of sun, planets and comets
Could only proceed from the counsel and dominion of
An intelligent and powerful being
Blind metaphysical necessity
Which is certainly the same always and everywhere
Could produce no variety of things
All that diversity of natural things
Which we find suited to different times and places
Could arise from nothing but the ideas
And will of a being necessarily existing

[Verse 2]

Here we find a universal method of checks and balancеs
Water promotes the еxistence of wood
Which promotes fire, which burns things to the earth
In the earth we find metals
Which through condensation promote the formation of water
However, water douses or controls fire
Which melts or controls metal
Which cuts or controls wood, which plows or controls earth
Which soaks up or controls water
Harmony requires checks and balances
If any one element becomes too strong or too weak
Imbalance occurs, illness sets in
And harmony is lost
[Verse 3]

A fifth element must be added to these four
To explain the behaviour of the heavenly bodies
Whereas the terrestrial elements of earth, water, air, and fire
Were all mutable and corruptible
Coming into being and passing away
No change could be perceived in the celestial realm
Moreover while the natural motion of the four terrestrial elements
Was towards or away from the centre of the cosmos in a straight line
The natural motion of the heavenly bodies was uniform circular motion
Around that centre
Therefore inferred
That the cosmos above the terrestrial sphere
That is, from the moon upwards
Was not made out of any of the mutable terrestrial elements
But must be composed of a different
Unchangeable substance, the fifth element
Or quintessence, which is Aether

Aether, an element that fills the universe beyond the terrestrial sphere
That's quintessential arts
