It has always appeared to me, that to give to the public some account of the life of a person of eminent merit deceased, is a duty incumbent on survivors. It seldom happens that such a person passes through life, without being the subject of thoughtless calumny, or malignant misrepresentation. It cannot happen that the public at large should be on a footing with their intimate acquaintance, and be the observer of those virtues which discover themselves principally in personal intercourse. Every benefactor of mankind is more or less influenced by a liberal passion for fame; and survivors only pay a debt due to these benefactors, when they assert and establish on their part, the honour they loved. The justice which is thus done to the illustrious dead, converts into the fairest source of animation and encouragement to those who would follow them in the same career. The human species at large is interested in this justice, as it teaches them to place their respect and affection, upon those qualities which best deserve to be esteemed and loved. I cannot easily prevail on myself to doubt, that the more fully we are presented with the picture and story of such persons as are the subject of the following narrative, the more generally shall we feel in ourselves an attachment to their fate, and a sympathy in their excellencies. There are not many individuals with whose character the public welfare and improvement are more intimately connected, than the author of A Vindication of the Rights of Woman. The facts detailed in the following pages, are principally taken from the mouth of the person to whom they relate; and of the veracity and ingenuousness of her habits, perhaps no one that was ever acquainted with her, entertains a doubt. The writer of this narrative, when he has met with persons, that in any degree created to themselves an interest and attachment in his mind, has always felt a curiosity to be acquainted with the scenes through which they had passed, and the incidents that had contributed to form their understandings and character. Impelled by this sentiment, he repeatedly led the conversation of Mary to topics of this sort; and, once or twice, he made notes in her presence, of a few dates calculated to arrange the circumstances in his mind. To the materials thus collected, he has added an industrious enquiry among the persons most intimately acquainted with her at the different periods of her life.
