Consequently it was the physicists, rather than the biologists, who put forward the paradoxical formulation of a ‘plasmic mechanism’, implying by this a structure, possibly without life as we conceive it, but capable of performing functional activities — on an astronomic scale, it should be emphasized.

It was during this quarrel, whose reverberations soon reached the ears of the most eminent authorities, that the Gamow-Shapely doctrine, unchallenged for eighty years, was shaken for the first time.

There were some who continued to support the Gamow-Shapley contentions, to the effect that the ocean had nothing to do with life, that it was neither ‘parabiological’ nor ‘prebiological’ but a geological formation — of extreme rarity, it is true — with the unique ability to stabilize the orbit of Solaris, despite the variations in the forces of attraction. Le Chatelier’s law was enlisted in support of this argument.

To challenge this conservative attitude, new hypotheses were advanced — of which Civito-Vitta’s was one of the most elaborate — proclaiming that the ocean was the product of a dialectical development: on the basis of its earliest pre-oceanic form, a solution of slow-reacting chemical elements, and by the force of circumstances (the threat to its existence from the changes of orbit), it had reached in a single bound the stage of ‘homeostatic ocean,’ without passing through all the stages of terrestrial evolution, by-passing the unicellular and multicellular phases, the vegetable and the animal, the development of a nervous and cerebral system. In other words, unlike terrestrial organisms, it had not taken hundreds of millions of years to adapt itself to its environment — culminating in the first representatives of a species endowed with reason — but dominated its environment immediately.

This was an original point of view. Nevertheless, the means whereby this collodial envelope was able to stabilize the planet’s orbit remained unknown. For almost a century, devices had existed capable of creating artificial magnetic and gravitational fields; they were called gravitors. But no one could even guess how this formless glue could produce an effect which the gravitors achieved by the use of complicated nuclear reactions and enormously high temperatures. The newspapers of the day, exciting the curiosity of the layman and the anger of the scientist, were full of the most improbable embroideries on the theme of the ‘Solaris Mystery,’ one reporter going so far as to suggest that the ocean was, no less, a distant relation to our electric eels!

Just when a measure of success had been achieved in unravelling this problem, it turned out, as often happened subsequently in the field of Solarist studies, that the explanation replaced one enigma by another, perhaps even more baffling.

Observations showed, at least, that the ocean did not react according to the same principles as our gravitors (which, in any case, would have been impossible), but succeeded in controlling the orbital periodicity directly. One result, among others, was the discovery of discrepancies in the measurement of time along one and the same meridian on Solaris. Thus the ocean was not only in a sense “aware” of the Einstein-Boëvia theory; it was also capable of exploiting the implications of the latter (which was more than we could say of ourselves).

With the publication of this hypothesis, the scientific world was torn by one of the most violent controversies of the century. Revered and universally accepted theories foundered; the specialist literature was swamped by outrageous and heretical treatises; ‘sentient ocean’ or ‘gravity-controlling colloid’ — the debate became a burning issue.

All this happened several years before I was born. When I was a student — new data having accumulated in the meantime — it was already generally agreed that there was life on Solaris, even if it was limited to a single inhabitant.

The second volume of Hughes and Eugel, which I was still leafing through mechanically, began with a systematization that was as ingenious as it was amusing. The table of classification comprised three definitions: Type: Polythera; Class: Syncytialia; Category: Metamorph.

It might have been thought that we knew of an infinite number of examples of the species, whereas in reality there was only the one — weighing, it is true, some seven hundred billion tons.

Multicolored illustrations, picturesque graphs, analytical summaries and spectral diagrams flickered through my fingers, explaining the type and rhythm of the fundamental transformations as well as chemical reactions. Rapidly, infallibly, the thick tome led the reader on to the solid ground of mathematical certitude. One might have assumed that we knew everything there was to be known about this representative of the category Metamorph, which lay some hundreds of metres below the metal hull of the Station, obscured at the moment by the shadows of the four-hour night.

In fact, by no means everybody was yet convinced that the ocean was actually a living ‘creature,’ and still less, it goes without saying, a rational one. I put the heavy volume back on the shelf and took up the one next to it, which was in two parts. The first part was devoted to a resumé of the countless attempts to establish contact with the ocean. I could well remember how, when I was a student, these attempts were the subject of endless anecdotes, jokes and witticisms. Compared with the proliferation of speculative ideas which were triggered off by this problem, medieval scholasticism seemed a model of scientific enlightenment. The second part, nearly 1500 pages long, was devoted exclusively to the bibliography of the subject. There would not have been enough room for the books themselves in the cabin in which I was sitting.

The first attempts at contact were by means of specially designed electronic apparatus. The ocean itself took an active part in these operations by remodelling the instruments. All this, however, remained somewhat obscure. What exactly did the ocean’s ‘participation’ consist of? It modified certain elements in the submerged instruments, as a result of which the normal discharge frequency was completely disrupted and the recording instruments registered a profusion of signals — fragmentary indications of some outlandish activity, which in fact defeated all attempts at analysis. Did these data point to a momentary condition of stimulation, or to regular impulses correlated with the gigantic structures which the ocean was in the process of creating elsewhere, at the antipodes of the region under investigation? Had the electronic apparatus recorded the cryptic manifestation of the ocean’s ancient secrets? Had it revealed its innermost workings to us? Who could tell? No two reactions to the stimuli were the same. Sometimes the instruments almost exploded under the violence of the impulses, sometimes there was total silence; it was impossible to obtain a repetition of any previously observed phenomenon. Constantly, it seemed, the experts were on the brink of deciphering the ever-growing mass of information. Was it not, after all, with this object in mind that computers had been built of virtually limitless capacity, such as no previous problem had ever demanded?

And, indeed, some results were obtained. The ocean as a source of electric and magnetic impulses and of gravitation expressed itself in a more or less mathematical language. Also, by calling on the most abstruse branches of statistical analysis, it was possible to classify certain frequencies in the discharges of current. Structural homologues were discovered, not unlike those already observed by physicists in that sector of science which deals with the reciprocal interaction of energy and matter, elements and compounds, the finite and the infinite. This correspondence convinced the scientists that they were confronted with a monstrous entity endowed with reason, a protoplasmic ocean-brain enveloping the entire planet and idling its time away in extravagant theoretical cognitation about the nature of the universe. Our instruments had intercepted minute random fragments of a prodigious and everlasting monologue unfolding in the depths of this colossal brain, which was inevitably beyond our understanding.
