1. The statement of facts by the Limitists is partial and essentially defective. They start with the assumption that a generalization is the highest form of human knowledge. To appreciate this fully, let us examine the process they thus exalt. A generalization is a process of thought through which one advances from a discursus among facts, to a conclusion, embodying a seemingly general truth, common to all the facts of the class. For instance. The inhabitants of the north temperate zone have long observed it to be a fact, that north winds are cold; and so have arrived at the general conclusion that such winds will lower the temperature. A more extensive experience teaches them, however, that in the south temperate zone, north winds are warm, and their judgment has to be modified accordingly. A yet larger investigation shows that, at one period in geologic history, north winds, even in northern climes, were warm, and that tropical animals flourished in arctic regions; and the judgment is again modified. Now observe this most important fact here brought out. _Every judgment may be modified by a larger experience._ Apply this to another class of facts. An apple is seen to fall when detached from the parent stem. An arrow, projected into the air, returns again. An invisible force keeps the moon in its orbit. Other like phenomena are observed; and, after patient investigation, it is found to be a fact, that there is a force in the system to which our planet belongs, which acts in a ratio inverse to the square of the distance, and which thus binds it together. But if a generalization is the highest form of knowledge, we can never be sure we are right, for a subsequent experience may teach us the reverse. We know we have not _all the facts_. We may again find that the north wind is elsewhere, or was once here, warm. Should a being come flying to us from another sphere so distant, that the largest telescope could catch no faintest ray, even, of its shining, and testify to us that there, the force we called gravitation, was inversely as the _cube_ of the distance, we could only accept the testimony, and modify our judgment accordingly. Conclusions of to-day may be errors to-morrow; and we can never know we are right. The Limitists permit us only interminable examinations of interminable changes in phenomena; which afford no higher result than a new basis for new studies. From this wearisome, Io-like wandering, the soul returns to itself, crying its wailing cry, "Is this true? Is this all?" when suddenly, as if frenzied by the presence of a god, it shouts exultingly "The truth! the truth! I see the eternal truth."
