The instructor attempts a personal application, endeavoring to give the disturbed conscience a rational direction, and a distinct cognizance. But he finds, as he might expect to find, that a conscience without knowledge has never taken but a very small portion of the man's habits of life under its jurisdiction; and that it is a most hopeless thing to attempt to send it back reinforced, to reclaim and conquer, through all the past, the whole extent of its rightful but never assumed dominion. So feeble and confined in the function of judgment through which it must see and act, it is especially incapable of admitting the monitor's estimate of the measure of guilt involved in omission, and in an irreligious state of the mind, as an exceedingly grave addition to the account of criminal action. The man is totally and honestly unable to conceive of the substantial guilt of anything of which he can ask, what injury it has done to anybody. This single point--whether positive harm has been done to any one--comprehends the whole essence and sum of the conscious accountableness of very ignorant people. Material wrong, _very_ material wrong, to their fellow mortals, they have a conscience that they should not do; a conscience, however, which they would deem it hard to be obliged to maintain entire even to this confined extent; and which therefore admits some compromise and gives some license, with respect especially to any kind of wrong which has the extenuation, as they deem it, of being commonly practised in their class; and against which there is a sort of understanding that each one must take the best care he can of himself. At this confine, so undecidedly marked, of practical, tangible wrong, these very ignorant persons lose the sense of obligation, and feel absolved from any further jurisdiction. So coarse and narrow a conscience as to what they _do_, is not likely to be refined and extended into a cognizance of what they _are_. As for a duty absolute in the nature of things, or as owing to themselves, in respect to their own nature, or as imposed by the Almighty--_that their minds should be in a certain prescribed state_--there does really require a perfectly new manner of the action of intellect to enable them to apprehend its existence. And this habitual insensibility to any jurisdiction over their internal state, now meets, in its consequences, the supposed instructor. In consideration of the vast importance of this part of a rational creature's accountableness, and partly, too, from a desire to avoid the invidiousness of appearing as a judicial censor of the sick man's practical conduct, he insists in an especial manner on this subject of the state within, endeavoring to expose that dark world by the light of religion to the sick man's conscience. But to give in an hour the _understanding_ which it requires the discipline of many years to render competent! How vain the attempt! The man's sense of guilt fixes almost
