It may here be proper to explain why these earliest of our perceptions are never remembered in after-life. The long period of human infancy, is a powerful argument for the superiority of our species: the mind of man is built up by his own exertions, and his progress is in the ratio of his experience to his capacity: his mission is more important, and consequently requires a longer period to fulfil: he has few instincts; and the sum of his knowledge is the elaboration of his extended endowments. To have remembered the confused dawnings of his perceptions, the imperfect and obscure transmissions of his unpractised organs would have been superfluous, and the sources of error. In this early state, there is no medium by which his perceptions can be artificially connected; nor do they admit of communication or record. When language is acquired, our perceptions become "doubly armed," and impress the memory with additional effect: the employment of the term as the representative of the object, recalls the original perception, and thus invests the mental phantasm with "a local habitation and a name." Thus our earliest recollections are never anterior to a certain progress in the art of speech. As we possess the instruments of motion in our muscles, they would have been useless without the performance of their function, and our bodies would have been stationary. It is also equally evident that this office must be performed by ourselves, or fulfilled by others. It has been already pointed out that there are certain motions, essential to the preservation of our animal system, termed _involuntary_, which do not originate from ourselves, but are the directions of a superior power, and are effected independently of our experience and control: the other motions, that have been termed voluntary, are the result of acquirement or practice, and have been gradually formed by our exertions. The reader will now be prepared to understand the wisdom of this arrangement, which, in a future chapter, will be more copiously treated; and to feel that the superiority of man, as an intellectual being, and a responsible agent, consists in the formation of his own mind, and in the direction of his thoughts and actions.
