4. Intellectual science has been observed to beget invariably a doubt of the existence of matter. Turgot said, "He that has never doubted the existence of matter, may be assured he has no aptitude for metaphysical inquiries." It fastens the attention upon immortal necessary uncreated natures, that is, upon Ideas; and in their presence, we feel that the outward circumstance is a dream and a shade. Whilst we wait in this Olympus of gods, we think of nature as an appendix to the soul. We ascend into their region, and know that these are the thoughts of the Supreme Being. "These are they who were set up from everlasting, from the beginning, or ever the earth was. When he prepared the heavens, they were there; when he established the clouds above, when he strengthened the fountains of the deep. Then they were by him, as one brought up with him. Of them took he counsel." Their influence is proportionate. As objects of science, they are accessible to few men. Yet all men are capable of being raised by piety or by passion, into their region. And no man touches these divine natures, without becoming, in some degree, himself divine. Like a new soul, they renew the body. We become physically nimble and lightsome; we tread on air; life is no longer irksome, and we think it will never be so. No man fears age or misfortune or death, in their serene company, for he is transported out of the district of change. Whilst we behold unveiled the nature of Justice and Truth, we learn the difference between the absolute and the conditional or relative. We apprehend the absolute. As it were, for the first time, _we exist_. We become immortal, for we learn that time and space are relations of matter; that, with a perception of truth, or a virtuous will, they have no affinity.
