“The time to read is any time: no apparatus, no appointment of time and place, is necessary. It is the only art which can be practiced at any hour of the day or night, whenever the time and inclination comes, that is your time for reading; in joy or sorrow, health or illness.” John Aiken, Letters from a father to his son (1796)
