We do not know in what the duty and happiness of other beings consist; but at least this seems to have been man's happiness in Paradise, not to think about himself or to be conscious of himself. Such, too, to recur to the parallel especially suggested on this day, seems to be the state of children. They do not reflect upon themselves. Such, too, seems to be the state of those orders of Angels whose life is said to consist in contemplation--for what is contemplation but a resting in the thought of God to the forgetfulness of self? Hence the Saints are described as "Virgins who _follow the Lamb whithersoever He goeth_." But Adam, discontented with what he was, pined after a knowledge which he could not obtain from without--which he could only have from miserable experience within--from moral disorders within him, and from having his mind drawn to the contemplation of himself in consequence of those disorders. He obtained the wished for knowledge; and his first recorded act afterwards was one of reflection upon self, and he hid himself among the trees of the garden. He was no longer fitted for contemplating glories without him; his attention was arrested to the shame that was upon him. What is so miserably seen in the history of our first parents has been the temptation and sin of their posterity ever since,--indulgence in forbidden, unlawful, hurtful, unprofitable knowledge; as some instances will show. 1. I ought to notice in the first place that evil curiosity which stimulates young persons to intrude into things of which it is their blessedness to be ignorant. Satan gains our souls step by step; and his first allurement is the knowledge of what is wrong. He first tempts them to the knowledge, and then to the commission of sin. Depend on it that our happiness and our glory, in these matters, is to be ignorant, as well as to be guiltless. St. Paul says that "it is a shame even to speak" of those things which are done by the sons of Belial in secret. Oh, thoughtless, and worse, oh, cruel to your own selves, all ye who read what ye should not read, and hear what ye should not hear! Oh, how will you repent of your folly afterwards! Oh, what bitter feelings, oh, what keen pangs, will shoot through your souls hereafter, at the memory, when you look back, of what has come of that baneful curiosity! Oh, how will you despise yourselves, oh, how weep at what you have brought on you! At this day surely there is a special need of this warning; for this is a day when nothing is not pried into, nothing is not published, nothing is not laid before all men.
