Let us state here at once, that this temporal distinction has an essential bearing on our understanding of evolutionary processes in general. For if mineral matter is a late product of evolution - and nothing in nature indicates the contrary - then to explain the origins of the world (as scientific theories have always done) with the aid of events similar in character to those which now occur in the mineral realm, means explaining them against nature's own evidence. To find pictures of past conditions of the earth in present-day nature, we must look in the regions where matter, because it is still 'youthful', is played through by the magical working of purposefully active spiritual forces. Thus, instead of seeing in them the chance results of blind volcanic and similar forces, we must recognize in the formation and layout of land and sea an outcome of events more closely resembling those which occur during the embryonic development of a living organism. What, then, does van Helmont's discovery of the gaseous state of matter tell us, if we regard it in the light of our newly acquired insight into the trend of evolution both within and without man? When, in the course of its growing older, mankind had reached the stage which is expressed by the emergence of the spectator-consciousness-consciousness, that is, based on a nervous system which has grown more or less independent of the life forces of the organism - the outer elements had, in their way, arrived at such a state that man began to inhale an air whose spiritual-physical constitution corresponded exactly to that of his nervous system: on either side, Spirit and Matter, in accordance with the necessities of cosmic evolution had lost their primeval union. * Our extension of the concept of evolution to the very elements of nature, whether these are of material or non-material kind, and our recognition of this evolution as leading in general from a more alert to a more inert condition, at once open the possibility of including in our scientific world-picture certain facts which have hitherto resisted any inclusion. We mean those manifold events of 'miraculous' nature, of which the scriptures and the oral traditions of old are full. What is modern man to make of them? The doubts which have arisen concerning events of this kind have their roots on the one hand in the apparent absence of such occurrences in our day, on the other in the fact that the laws of nature derived by science from the present condition of the world seem to rule them out.5 In the light of the concept of the world's 'ageing' which we have tried to develop here, not only do the relevant reports become plausible, but it also becomes understandable why, if such events have taken place in the past, they fail to do so in our own time. To illustrate this, let us take a few instances which are symptomatic of the higher degree of youthfulness which was characteristic in former times in particular of the element of Fire.
