To-day we take the word Chaos to mean a condition of mere absence of order, mostly resulting from a destruction of existing forms, whether by nature or by the action of man. In its original sense the word meant the exact opposite. When in ancient times people spoke of Chaos, they meant the womb of all being, the exalted realm of uncreated things, where indeed forms such as are evident to the eye in the created world are not to be found, but in place of them are the archetypes of all visible forms, as though nurtured in a spiritual seed-condition. It is the state which in the biblical narration of the creation of the world is described as 'without form and void'. From this Chaos all the four elements are born, one by one, with the two upper ones retaining Chaos's essential characteristic in that they are 'without form' and tend to be omnipresent, whilst the two lower ones constitute a realm in which things appear in more or less clearly outlined space-bound forms. This is what the terms 'uncreated' and 'created' imply. How strictly these two realms were distinguished can be seen by the occurrence of the concept 'vapour'. When with the increasing interest in the realm of created things - characteristic of the spectator-consciousness which, in view of our earlier description of it, we recognize as being itself a 'created thing' - the need arose for progressive differentiation within this realm, the simple division of it into 'earth' and 'water' was no longer felt to be satisfactory. After all, above the liquid state of matter there was another state, less dense than water and yet presenting itself through more or less clearly distinguishable space-bound objects, such as the mists arising from and spreading over ponds and meadows, and the clouds hovering in the sky. For this state of matter the term 'vapour' had become customary, and it was used by van Helmont in this sense. By its very properties, Vapour belonged to the realm of the created things, whereas Air did not. It was the intermediary position of the newly discovered state of matter between Vapour and Air, that is, between the created and the uncreated world, which caused van Helmont to call it a paradox; and it was its strange resemblance, despite its ponderable nature, to Chaos, which prompted him to name it - Gas. * Since it could not have been the gaseous state of matter in the form discovered by van Helmont, what particular condition of nature was it to which the ancients pointed when using the term Air? Let us see how the scriptures of past human cultures speak of air.
