It is an old, but a very true observation, that the human mind must ever be employed. A relish for reading, or any of the fine arts, should be cultivated very early in life; and those who reflect can tell, of what importance it is for the mind to have some resource in itself, and not to be entirely dependant on the senses for employment and amusement. If it unfortunately is so, it must submit to meanness, and often to vice, in order to gratify them. The wisest and best are too much under their influence; and the endeavouring to conquer them, when reason and virtue will not give their sanction, constitutes great part of the warfare of life. What support, then, have they who are all senses, and who are full of schemes, which terminate in temporal objects?
Reading is the most rational employment, if people seek food for the understanding, and do not read merely to remember words; or with a view to quote celebrated authors, and retail sentiments they do not understand or feel. Judicious books enlarge the mind and improve the heart, though some, by them, "are made coxcombs to whom nature meant for fools."
Mary Wollstonecraft, Thoughts on the Education of Daughters, pp. 48-49. The quotation is from Alexander Pope's An Essay on Criticism.
