He had not intended to marry. He was thirty-five, and dedicated to his work. He felt it was a noble work, this patient proving to ignorance and prejudice of what could be done with barrenness if only you mixed it with brains. He was fairly comfortable in his housekeeping, having found a woman who was a widow and had therefore learned the great lesson that only widows ever really know, that a man must be let alone. He was poor, and what he could spare by rigid economies went into the few acres of sand that were to be the Light he had to offer to lighten the Gentiles. Every man, he thought, should offer some light to the abounding Gentiles before he died, some light which, however small, might be kept so clear that they could not choose but see it. A wife, he had felt when considering the question from time to time, which was each year in the early spring, would come between him and his light. She would be a shadow; and a voluminous, all-enveloping shadow. His church and the business of preaching in it were already sufficiently interrupting, but they were weekly. A wife would be every day. He could lock her out of the laboratory, he would reflect, and perhaps also out of the sitting-room.... When he became aware that he was earnestly considering what other rooms he could lock her out of, and discovered that he would want to lock her out of nearly all, he, as a wise and honest man, decided he had best leave the much-curved virgins of the neighbourhood alone. The question occupied him regularly every year in the first warm days of spring. For the rest of the year he mostly forgot it, absorbed in his work. And here he was on the top of the Rigi, a cool place, almost, wintry, with it suddenly become so living that compared to it his fertilizers seemed ridiculous.
