Thought can discriminate abstractions long before it can discriminate facts in their relations with Life. It can reason logically of the true and the false in the realms of the mind long before it can tell the right from the wrong with correctness and readiness in the daily ongoings of events. To discriminate justly here, we must be able to dissipate the mists with which the love of self and the love of the world obscure the way in which we tread; hiding that which we _ought_ to love, and displaying in enlarged proportions the things that we _do_ love, until reason loses all just data, and accepts whatever passion offers as foundation for its judgments. Persons thus misled, often think they really meant to walk steadfastly in the right path, and that they are not responsible for having wandered into the wrong. They call what they have done an error of judgment, and rest content in the belief that their intentions were good, and therefore they are not to blame. This may be true, for "to err is human," and none but the All-wise can be sure of always judging rightly. Still, when we know that we have done wrong through an error of judgment, we should carefully examine and see if we might not have avoided this mistake had we been more careful in our investigation of facts,--more conscientious in our process of adopting our opinions. If we thus catechized our past errors, we should probably find, that, in a large proportion of cases, our error sprang from some cause we might have prevented,--from carelessness, from blindness caused by the desire to gratify our own wishes, or from indolence; in fact, that what we fancied sprang from an error of judgment only, had a much deeper root, and drew its nourishment from undisciplined Affections. In training the faculty of discrimination, the work we must set before ourselves is to learn the relative value of principles, of persons, and of things; and in order to do this, we must look upon them in their relations with time and with eternity. We must learn to value and to judge from laws of absolute right, and not from the expediencies of the hour.
