In your progress through life, be not so vain as to believe that you will escape the evils with which its path is beset. Arm yourselves, therefore, with the talisman that can, at once, deprive adversity of its sting, and prosperity of its dangers; for such, believe me, is the rare privilege of philosophy. I must now take leave of you, for a short time, in order that I may address a few words to your parents and preceptors; but, as I have no plot to abridge your liberties, or lengthen your hours of study, you may listen to my address without alarm, and to my plan without suspicion. Imagine not, however, that I shall recommend the dismissal of the cane, or the whip; on the contrary, I shall insist upon them as necessary and indispensable instruments for the accomplishment of my design. But the method of applying them will be changed; with the one I shall construct the bow of the kite, with the other I shall spin the top. The object of the present work is to inculcate that early love of science which can never be derived from the sterner productions. Youth is naturally addicted to amusement, and in this item his expenditure too often exceeds his allotted income. I have, therefore, taken the liberty to draw a draft upon Philosophy, with the full assurance that it will be gratefully repaid, with compound interest, ten years after date. But to be serious; those who superintend the education of youth should be apprised of the great importance of the first impressions. Rousseau has said, that the seeds of future vices or virtues are more frequently sown by the mother than the tutor; thereby intimating, that the characters of men are often determined by the earliest impressions; and, of so much moment did Quintillian regard this truth, that he recommends to us the example of Philip, who did not suffer any other than Aristotle to teach Alexander to read. In like manner those who do not commence their study of nature at an early season, will afterwards have many unnecessary obstacles to encounter. The difficulty of comprehending the principles of Natural Philosophy frequently arises from their being at variance with those false ideas which early associations have impressed upon the mind; the first years of study are, therefore, expended in _un_learning, and in clearing away the weeds, which would never have taken root in a properly cultivated soil. Writers on practical education have repeatedly advocated the advantages of the plan I am so anxious to enforce; but, strange to say, it is only within a few years that any works have appeared at all calculated to afford the necessary assistance. In short, previous to the labours of Mrs. Marcet and Miss Edgeworth, the productions published for the purpose of juvenile instruction may be justly charged with the grossest errors; and must have proved as destructive to the mind of the young reader, as the book presented by the physician Douban is said to have
