These paradoxes, of course, could be explained in part by the things that Lithia lacked. Like any large rotating mass, Lithia had a magnetic field of its own, but a planet which almost entirely lacks iron provides its people with no easy way. to discover magnetism. Radioactivity had been entirely unknown on the surface of Lithia, at least until the Earthmen had arrived, which explained the hazy atomic theory. Like the Greeks, the Lithians had discovered that friction between silk and glass produces one kind of energy or charge, and between silk and amber another; they had gone on from there to van de Graaf generators, electrochemistry, and the static jet — but without suitable metals they were unable to make heavy-duty batteries, or to do more than begin to study electricity in motion.
In the fields where they had been given fair clues, they had made enormous progress. Despite the constant cloudiness and endemic drizzle, their descriptive astronomy was excellent, thanks to the fortunate presence of a small moon which had drawn their attention outward early. This in turn made for basic advances in optics, and thence for a downright staggering versatility in the working of glass. Their chemistry took full advantage of both the seas and the jungles. From the one they took such vital and diversified products as agar, iodine, salt, trace metals, and foods of many kinds. The other provided nearly everything else that they needed: resins, rubbers, woods of all degrees of hardness, edible and essential oils, vegetable "butters," rope and other fibers, fruits and nuts, tannins, dyes, drugs, cork, paper. Indeed, the sole forest product which they did not take was game, and the reason for this neglect was hard to find. It seemed to the Jesuit to be religious — yet the Lithians had no religion, and they certainly ate many of the creatures of the sea without qualms of conscience.
He dropped the jungle suit into his lap with a sigh, though the popcorned tooth still was not completely trimmed hack into shape. Outside, in the humid darkness, Lithia was in full concert. It was a vital, somehow fresh, new-sounding drone, covering most of the sound spectrum audible to an Earthman. It came from the myriad insects of Lithia. Many of these had wiry, trilling songs, almost like birds, in addition to the scrapes and chirrups and wing-case buzzes of the insects of Earth. In a way this was lucky, for there were no birds on Lithia. Had Eden sounded like that, before evil had come into the world? Ruiz-Sanchez wondered. Certainly his native Peru sang no such song…
Qualms of conscience — these were, in the long run, his essential business, rather than the taxonomical mazes of biology, which had already become tangled into near-hopelessness on Earth before space flight had come along to add whole new layers of labyrinths for each planet, new dimensions of labyrinths for each star. It was only interesting that the Lithians were bipedal, evolved from reptiles, with marsupial-like pouches and pteropsid circulatory systems. But it was vital that they had qualms of conscience — if they did.
The calendar caught his eye. It was an "art" calendar Cleaver had produced from his luggage back in the beginning; the girl on it was now unintentionally modest beneath large patches of brilliant orange mold. The date was April 19, 2049. Almost Easter — the most pointed of reminders that to the inner life, the body was only a garment. To Ruiz-Sanchez personally, however, the year date was almost equally significant, for 2050 was to be a Holy Year.
The Church had returned to the ancient custom, first recognized officially in 1300 by Boniface VIII, of proclaiming the great pardon only once every half-century. If Ruiz-Sanchez was not in Rome next year when the Holy Door was opened, it would never be opened again in his lifetime.
Hurry, hurry! some personal demon whispered inside his brain. Or was it the voice of his own conscience? Were his sins already so burdensome — unknown to himself — as to put him in mortal need of the pilgrimage? Or was that, in turn, only a minor temptation, to the sin of pride?
In any event, the work could not be hurried. He and the other three men were on Lithia to decide whether or not the planet would be suitable as a port of call for Earth, without risk of damage either to Earthmen or to Lithians. The other three men on the commission were primarily scientists, as was Ruiz-Sanchez; but he knew that his own recommendation would in the long run depend upon conscience, not upon taxonomy.
And conscience, like creation, cannot be hurried. It cannot even be scheduled.
He looked down at the still-imperfect jungle suit with a troubled face until he heard Cleaver moan. Then he arose and left the room to the softly hissing flames.
