The progress of manufactures and commerce insensibly collects a large multitude within the walls of a city: but these citizens are no longer soldiers; and the arts which adorn and improve the state of civil society, corrupt the habits of the military life.
Edward Gibbon[A] military force was collected in Europe, formidable by their arms and numbers, if the generals had understood the science of command, and the soldiers the duty of obedience.
Edward GibbonAmong the innumerable monuments of architecture constructed by the Romans, how many have escaped the notice of history, how few have resisted the ravages of time and barbarism! And yet even the majestic ruins that are still scattered over Italy and the provinces, would be sufficient to prove that those countries were once the seat of a polite and powerful empire.
Edward GibbonAlthough the progress of civilisation has undoubtedly contributed to assuage the fiercer passions of human nature, it seems to have been less favourable to the virtue of chastity, whose most dangerous enemy is the softness of the mind. The refinements of life corrupt while they polish the intercourse of the sexes. The gross appetite of love becomes most dangerous when it is elevated, or rather, indeed, disguised by sentimental passion.
