The role which Fire was capable of playing in man's life at a time when even this element, in itself the most youthful of all, was more susceptible to magic interference than of late, is shown by the manifold fire-rites of old. In those days, when no easy means of fire-lighting were available, it was usual for the needs of daily life to keen a fire burning all the time and to kindle other fires from it. Only in cases of necessity was a new fire lit, and then the only way was by the tedious rubbing together of two pieces of dry wood.
Then both the maintenance of fires, and the deliberate kindling of a new fire, played quite a special role in the ceremonial ordering of human society. Historically, much the best known is the Roman usage in the Temple of Vesta. On the one hand, the unintentional extinction of the fire was regarded as a national calamity and as the gravest possible transgression on the part of the consecrated priestess charged with maintaining the fire. On the other hand, it was thought essential for this 'everlasting' fire to be newly kindled once a year. This took place with a special ritual at the beginning of the Roman year (1st March).
The conception behind such a ritual of fire-kindling will become clear if we compare with it certain other fire-rites which were practised in the northern parts of Europe, especially in the British Isles, until far on in the Christian era. For example, if sickness broke out among the cattle, a widespread practice was to extinguish all the hearth-fires in the district and then to kindle with certain rites a new fire, from which all the local people lit their own fires once more. Heavy penalties were prescribed for anyone who failed to extinguish his own fire - a failure usually indicated by the non-manifestation of the expected healing influence. In Anglo-Saxon speaking countries, fires of this kind were known as 'needfires'.
The spiritual significance of these fires cannot be expressed better than by the meaning of the very term 'needfire'. This word does not derive, as was formerly believed, from the word 'need', meaning a 'fire kindled in a state of need', but, as recent etymological research has shown, from a root which appears in the German word nieten - to clinch or rivet. 'Needfire' therefore means nothing less than a fire which was kindled for 'clinching' anew the bond between earthly life and the primal spiritual order at times when for one reason or another there was a call for this.
This explanation of the 'needfire' throws light also on the Roman custom of re-kindling annually the sacred fire in the Temple of Vesta. For the Romans this was a means of reaffirming year by year the connexion of the nation with its spiritual leadership; accordingly, they chose the time when the sun in its yearly course restores - 're-clinches' - the union of the world-spirit with earthly nature, for the rebirth of the fire which throughout the rest of the year was carefully guarded against extinction.
Just as men saw in this fire-kindling a way of bringing humanity into active relation with spiritual powers, so on the other hand were these powers held to use the fire element in outer nature for the purpose of making themselves actively known to mankind. Hence we find in the records of all ancient peoples a unanimous recognition of lightning and thunder on the one hand, and volcanic phenomena on the other, as means to which the Deity resorts for intervening in human destiny. A well-known example is the account in the Bible of the meeting of Moses with God on Mount Sinai. As occurrence in the early history of the Hebrews it gives evidence that even in historical times the fire element of the earth was sufficiently 'young' to serve the higher spiritual powers as an instrument for the direct expression of their will.
(b) LEVITY contra GRAVITY
We said earlier in this chapter that a science which aspires to a spiritual understanding of the physical happenings in nature must give up the idea that inertness and weight are absolute properties of matter. We were able at once to tackle the question of inertness by bringing to our immediate observation matter in the state of diminished inertness, or, as we proposed to say, of alertness. We are now in a position to go into the other question, that of weight or gravity. Just as we found inertness to have its counterpart in alertness, both being existing conditions of matter, so we shall now find in addition to the force of gravity another force which is the exact opposite of it, and to which therefore we can give no better name than 'levity'.

Already, indeed, the picture of nature which we gained from following Goethe's studies both of the plant and of meteorological happenings has brought us face to face with certain aspects of levity. For when Goethe speaks of systole and diastole, as the plant first taught him to see them and as later he found them forming the basic factors of weather-formation, he is really speaking of the ancient concepts, 'cold' and 'warm'. Goethe's way of observing nature is, in fact, a first step beyond the limits of a science which kept itself ignorant of levity as a cosmic counterpart to terrestrial gravity. To recognize the historical significance of this step, let us turn our glance to the moment when the human mind became aware that to lay a proper foundation for the science it was about to build, it had to exclude any idea of levity as something with a real existence.
