“Friendship and domestic happiness are continually praised; yet how little is there of either in the world, because it requires more cultivation of mind to keep awake affection, even in our own hearts, than the common run of people suppose.”

Mary Wollstonecraft book Letters Written During a Short Residence in Sweden, Norway, and Denmark

Letter 12
Letters Written in Sweden (1796)
Context: Friendship and domestic happiness are continually praised; yet how little is there of either in the world, because it requires more cultivation of mind to keep awake affection, even in our own hearts, than the common run of people suppose. Besides, few like to be seen as they really are; and a degree of simplicity, and of undisguised confidence, which, to uninterested observers, would almost border on weakness, is the charm, nay the essence of love or friendship, all the bewitching graces of childhood again appearing.

“Since… nature is a principle of motion and mutation… it is necessary that we should not be ignorant of what motion is… But motion appears to belong to things continuous; and the infinite first presents itself to the view in that which is continuous. …[F]requently …those who define the continuous, employ the nature or the infinite, as if that which is divisible to infinity is continuous.”
