Alexander who was passionately fond of reading and whilst the world resounded with his victories, whilst blood and carnage marked his progress, whilst he dragged captive monarchs at his chariot wheels, and marched with increasing ardor over smoking towns and desolated provinces in search of new objects of victory, felt during certain intervals, the langors of unemployed time; and lamenting that Asia afforded no books to amuse his leisure, he wrote to Harpalus to send him the works of Philistus, the tragedies of Euripides, Sophocles, Æschylus, and the dithyrambics of Thalestes. Brutus, the avenger of the violated liberties of Rome, while serving in the army under Pompey, employed among books all the moments he could spare from the duties of his station; and was even thus employed during the awful night which preceded the celebrated battle of Pharsalia, by which the fate of the empire was decided. Oppressed by the excessive heat of the day, and by the preparatory arrangement of the army, which was encamped in the middle of summer on a marshy plain, he sought relief from the bath, and retired to his tent, where, whilst others were locked in the arms of sleep, or contemplating the event of the ensuing day, he employed himself until the morning dawned, in drawing a plan from the History of Polybius. Cicero, who was more sensible of mental pleasures than any other character, says, in his oration for the poet Archias, “Why should I be ashamed to acknowledge pleasures like these, since for so many years the enjoyment of them has never prevented me from relieving the wants of others, or deprived me of the courage to attack vice and defend virtue? Who can justly blame, who can censure me, if, while others are pursuing the views of interest, gazing at festal shows and idle ceremonies, exploring new pleasures, engaged in midnight revels, in the distraction of gaming, the madness of intemperance, neither reposing the body, nor recreating the mind, I spend the recollective hours in a pleasing review of my past life, in dedicating my time to learning and the muses?” Pliny the elder, full of the same spirit devoted every moment of his life to learning. A person read to him during his meals; and he never travelled without a book and a portable writing-desk by his side. He made extracts from every work he read; and scarcely conceiving himself alive while his faculties were absorbed in sleep, endeavored by his diligence, to double the duration of his existence.
