Another means of preserving health, to be attended to, is the having a constant supply of fresh air in your bed-chamber. It has been a great mistake, the sleeping in rooms exactly closed, and in beds surrounded by curtains. No outward air that may come in to you is so unwholesome as the unchanged air, often breathed, of a close chamber. As boiling water does not grow hotter by longer boiling, if the particles that receive greater heat can escape; so living bodies do not putrefy, if the particles, so fast as they become putrid, can be thrown off.
– B. Franklin, ‘The Art of Procuring Pleasant Dreams’
Freedom of thought — freedom from thought — thoughtful, thoughtless liberty.
