It is evident that these mutual obligations did not originate in the law of nature, but in the law of society; and that the claim of social duty was more stringent than that of mere humanity. These services were not supposed to be due from man to man, but to the vassal or to the lord. Feudal institutions awakened a lively sympathy for the sufferings of certain men, but none at all for the miseries of mankind. They infused generosity rather than mildness into the manners of the time, and although they prompted men to great acts of self-devotion, they engendered no real sympathies; for real sympathies can only exist between those who are alike; and in aristocratic ages men acknowledge none but the members of their own caste to be like themselves. When the chroniclers of the Middle Ages, who all belonged to the aristocracy by birth or education, relate the tragical end of a noble, their grief flows apace; whereas they tell you at a breath, and without wincing, of massacres and tortures inflicted on the common sort of people. Not that these writers felt habitual hatred or systematic disdain for the people; war between the several classes of the community was not yet declared. They were impelled by an instinct rather than by a passion; as they had formed no clear notion of a poor man's sufferings, they cared but little for his fate. The same feelings animated the lower orders whenever the feudal tie was broken. The same ages which witnessed so many heroic acts of self-devotion on the part of vassals for their lords, were stained with atrocious barbarities, exercised from time to time by the lower classes on the higher. It must not be supposed that this mutual insensibility arose solely from the absence of public order and education; for traces of it are to be found in the following centuries, which became tranquil and enlightened whilst they remained aristocratic. In 1675 the lower classes in Brittany revolted at the imposition of a new tax. These disturbances were put down with unexampled atrocity. Observe the language in which Madame de Sevigne, a witness of these horrors, relates them to her daughter:-- "Aux Rochers, 30 Octobre, 1675.
