Another thing may cause astonishment, and that is why as I approached this burning globe I was not consumed, since I had almost reached the full activity of its sphere. This is the reason: properly speaking it is not the fire itself which burns, but a grosser matter which the fire thrusts hither and thither by the vehemence of its mobile nature; and that powder of sparkles which I call fire, moving of itself, finds all this action possible from the roundness of its atoms; for they caress, heat or burn according to the shape of the bodies they draw with them. Thus, straw does not send out so hot a flame as wood; wood burns with less violence than iron, and the reason for this is that the fire of iron, wood and straw, although it is the same fire, nevertheless acts differently, according to the diversity of the bodies it moves; that is why in straw the fire (that almost spiritual dust) is less corrosive, because it is hindered by a soft body only; in wood, whose substance is more compact, it enters more harshly; and in iron, whose mass is almost entirely solid and bound together with angular parts, it penetrates and consumes what is cast upon it in a flash. All these observations are so familiar that no one will be surprised that I approached the sun without being burned, because that which burns is not fire, but the matter to which it is attached, and because the Sun's fire cannot be mingled with any matter. Do we not experience ourselves that joy, which is a fire, because it only moves an aery blood, whose very loose particles slide gently against the membranes of our flesh, caresses us and creates I know not what blind pleasure, and that this pleasure or rather this first step of pain, not going so far as to menace the animal with death, but making him feel his good constitution by a natural instinct, causes a movement in our minds which we call joy? Fever, which has entirely contrary effects, is a fire just as much as joy, but it is a fire enveloped in a body whose grains are horny, such as black bile or melancholy, and this fire darting its hooked points everywhere, its mobile nature carries it, pierces, cuts, flays and produces by this violent agitation what is called the burning of fever. But this chain of proofs is quite useless; the commonest experiments are sufficient to convince the most obstinate. I have no time to lose, I must think of myself; like Phaethon, I am in the midst of a career, where I cannot turn back, and in which if I make one false step all Nature together cannot help me.

I perceived very distinctly, as I had formerly suspected in travelling to the Moon, that it is indeed the Earth which turns about the Sun from East to West, and not the Sun which turns about the Earth; for I saw in succession France, the foot of the boot of Italy, then the Mediterranean, then Greece, then the Bosphorus, the Euxine Sea, Persia, the Indies, China and finally Japan pass across the hole of my box, and some hours after my elevation the whole South Sea passed by and left in its place the Continent of America. I clearly distinguished all these revolutions and I even remember that a long time afterwards I again saw Europe moving up once more on the scene, but I could not distinguish the different States, because my elevation was now too high. On my way I passed, sometimes on the left, sometimes on the right, several worlds like ours and I felt myself deflected whenever I reached the spheres of their activity. However, the rapid vigour of my upward flight overcame these attractions.

I passed near the Moon, which at that time was between the Sun and the Earth, and I left Venus on the right hand. As touching this star, the old Astronomy has so preached that the planets are spheres which turn around the Earth that modern Astronomy dare not doubt it. And yet I noticed that as long as Venus appeared on this side of the Sun, around which she turns, I saw her as a crescent; but as she continued her orbit I noticed that in proportion as she passed behind the Sun the horns drew together and her black belly became golden. This alternation of light and darkness showed very plainly that the planets, like the Moon and the Earth, are globes without light of their own and are only capable of reflecting what they borrow. Moreover, as I continued to rise, I made the same observation in the case of Mercury. I also noticed that all these worlds have other little worlds moving about them. Musing afterwards on the causes of the construction of this great Universe I have supposed that at the disentangling of chaos, after God had created matter, like bodies were joined to like bodies, through that unknown principle of love, whereby we see that everything seeks its like. Particles formed in a certain way joined together and that made the air; others, whose shape perhaps gave them a circular movement, gathered together and composed the globes we call planets, which, accumulated in the round shape we see, because of that inclination to spin on their poles to which their shape forces them; and also they cause those lesser orbs, which are met with in the sphere of their activity, to turn likewise, since these evaporate from their mass and move in their flight on a similar course. That is why Mercury, Venus, the Earth, Mars, Jupiter and Saturn have been forced to spin and roll all together around the Sun. It is quite possible to imagine that these globes may formerly have been Suns, since, in spite of its present extinction, the Earth still retains sufficient heat to cause the Moon to turn about through the circular movement of the bodies which are detached from its mass, and Jupiter has enough to turn four. But in the course of time, owing to the continual emission of the little bodies which make heat and light, these Suns have lost so much of their heat and light that they remain a cold, dark and almost impotent residuum. We even discover that the spots in the Sun, which were not perceived by the Ancients, increase from day to day. How do we know that this is not a crust forming on its outer surface, that its mass grows fainter as the light abandons it and that, when all these mobile bodies abandon it, it will not become an opaque globe like the Earth?[57] There are very distant centuries beyond which there appears no vestige of the human race; perhaps the Earth was formerly a Sun peopled with animals fitted for the climate, which had produced them, and perhaps these animals were the demons whereof Antiquity relates so many examples. Why not? Might it not be that these animals still inhabited the Earth for a time after its extinction and that the change in their globe did not destroy their whole race at once? In fact, their life lasted until the time of Augustus, according to Plutarch. It even appears that the sacred and prophetic Testament of our first Patriarchs meant to lead us by the hand to this truth; for, before man is spoken of, we read of the revolt of the Angels. This sequence of time observed by the Scriptures is perhaps a half-proof that Angels inhabited the Earth before us and that these proud beings, who had dwelt in our World since it was a Sun, disdaining to continue there perhaps when it was extinguished and knowing that God had placed His throne in the Sun, dared to undertake to occupy it? But God, desirous of punishing their insolence, drove them out of the Earth and to occupy their vacant place created man less perfect but therefore less proud.

At the end of about four months' travelling, at least as nearly as can be calculated, when there is no night to distinguish one day from another, I reached one of those little Worlds which fly around the Sun, called by Mathematicians "Spots". There my mirrors did not collect so much heat on account of the intervening clouds; consequently the air did not drive my cabin with so much vigour and there was only sufficient wind to break my fall and set me down on the point of a very high mountain, where I gently landed.

I leave you to imagine the joy I felt at seeing my feet on a solid floor after having played the part of a bird so long. Words indeed are too weak to express the happiness with which I trembled when at last I perceived my head crowned with the light of the Heavens. Yet this ecstasy did not so transport me but that I remembered as I left my box to cover its top with my shirt before going away from it, because if the air became serene, as was very probable, I apprehended the Sun would relight my mirrors and I should lose my house.

By way of gorges, which traces of water showed had been hollowed out by its action, I reached the plain, where I could scarcely walk on account of the thickness of the soil with which the earth was fat; nevertheless, after walking for some time I reached a quagmire, where I met a little man entirely naked sitting on a stone to repose himself. I do not remember if I spoke the first or if he questioned me; but it is fresh in my memory, as if I had just heard him, that he discoursed to me for three long hours in a language which I know I had never heard before, which bore no relation to any in this world, yet which I understood more quickly and more intelligibly than my nurse's. He explained to me, when I inquired about so marvellous a thing, that in the sciences there is one Truth, outside which one is always distant from what is easy; that the more distant an idiom is from this truth the further it is below one's conception and the less easy it is to understand.

"In the same way", he continued, "this Truth is never met with in music but that the uplifted soul immediately moves blindly towards it. We do not see it, but we feel that Nature sees it; and without being able to understand how it is we are absorbed, it does not fail to delight us and yet we cannot tell where it is. It is just the same with languages; whoever hits upon this Truth of letters, words and sequence in expressing himself can never fall below his conception; his speech is always equal to his thought; and it is because you do not possess this perfect idiom that you hesitate, and do not know what order or what words can express what you imagine."

I told him that the first man in our world had indubitably made use of this mother-tongue, because every name he had imposed upon every thing declared its essence. He interrupted me and continued:

"It is not merely needed to express all the mind conceives, but without it one cannot be understood by all. Since this idiom is the instinct or the voice of Nature, it ought to be intelligible to everything which lives under Nature's jurisdiction; and so if you understand it you can communicate and speak all your thoughts to beasts and the beasts all their thoughts to you, because it is the very language of Nature by which she makes herself understood by all animals. Therefore you should not be surprised by the ease with which you understand the meaning of a language that never before sounded in your hearing. When I speak, your soul meets in every one of my words that Truth it gropes for; and although your soul's reason does not understand it, the soul has in it Nature which cannot fail to understand this language."

"Ah! without doubt", I cried, "it was by means of this energetic idiom that our first Father of old talked with the animals and was understood by them; domination over all kinds had been given him and they obeyed him, because he made them obey in a language which was known to them; and this mother-tongue, being now lost, they no longer come to us when we call them as formerly, because they no longer understand us."
