The ideas of Sense are more strong, lively, and distinct than those of the Imagination; they have likewise a steadiness, order, and coherence, and are not excited at random, as those which are the effects of human wills often are, but in a regular train or series--the admirable connection whereof sufficiently testifies the wisdom and benevolence of its Author. Now the set rules, or established methods, wherein the Mind we depend on excites in us the ideas of Sense, are called _the laws of nature_."[294:18] Of the attributes of experience here in question, independence or "steadiness" is not regarded as _prima facie_ evidence of spirit, but rather as an aspect of experience for which some cause is necessary. But it is assumed that the power to "produce," with which such a cause must be endowed, is the peculiar prerogative of spirit, and that this cause gives further evidence of its spiritual nature, of its eminently spiritual nature, in the orderliness and the goodness of its effects. "The force that produces, the intellect that orders, the goodness that perfects all things is the Supreme Being."[294:19] That spirit is possessed of causal efficacy, Berkeley has in an earlier passage proved by a direct appeal to the individual's sense of power. "I find I can excite ideas in my mind at pleasure, and vary and shift the scene as oft as I think fit. It is no more than _willing_, and straightway this or that idea arises in my fancy; and by the same power it is obliterated and makes way for another. This making and unmaking of ideas doth very properly denominate the mind active. Thus much is certain and grounded on experience: but when we talk of unthinking agents, or of exciting ideas exclusive of volition, we only amuse ourselves with words."[295:20]
