“The following thoughts, my dear children, are those of an affectionate father going out of life, to those he most loves, who are coming forward in it. I am perfectly aware, that nothing but time can impart all the dear bought instruction of experience. Upon innumerable questions, that relate to life, you will receive efficient teaching only by reaping the fruit of your own errors. But one who has preceded you on the journey, who has listened to the impressive oracles of years, may impart some aid if you will listen with docility, to enable you to anticipate the lessons of experimental acquaintance with the world. In what I am about to write, I trust I may bring you this aid. As you embark on the uncertain voyage, I cannot but hope, that your filial piety will incline you to a frequent recurrence to the parental chart. You are aware, that circumstances have brought me into contact with all conditions, and into a view of all the aspects of life. I ought, therefore, to be qualified to impart useful lessons upon the evils and dangers of inexperience. You, at least, will not see assumption in such lessons, when they result from the remembrance of my own errors. You may consider what follows, whether it be my own remarks, or what I have adopted from others, as the gleanings of experimental instruction, from what I have myself seen, felt, suffered, or enjoyed; and as my comments upon the influence, which my election of alternatives has had, upon the amount of my own enjoyment or suffering”.
