DEDICATION.

AUGUST and sacred names of LOCKE and CONDILLAC! and you, virtuous SICARD, who, by the effulgence of your genius, have illumined the most dark and abstract subjects, and, by a most scrutinizing attention to the faculties of the human mind, reinstated a portion of his race in the possession of such characteristics of humanity as Nature withheld! accept a small but sincere tribute of veneration and gratitude in the dedication of the following work, by

THE AUTHOR.

ΤΟ

MY MOTHER.

HAVING discharged the debt of gratitude which was due to the instructors of my youth, by offering them the first fruits of my literary labours, committed to the press, I cannot, my Affectionate Parent, withhold from You the homage of my respect and the tribute of my acknowledgment. How numerous and how just are the claims You possess! You, who considered it of less moment to have given me existence than to have cultivated my mind; You, who, to the care of an anxious father for my education, added Your persevering attention; and while he endeavoured to improve my mind, and form my taste for knowledge, by frequently describing the glory of Montesquieu, Buffon, and Pascal, You strove to exalt my sentiments, by fixing generous principles in my breast; You, who, when the French Revolution burst forth (that awful lesson given by an all-wise Teacher to sovereigns and to nations!), evinced that those principles ennobled Your own soul, which it was Your ambition to implant in mine.
