"An antient philosopher indeed, full of real or pretended honesty, declared it to be his wish that there were a window in his breast that every body might see the integrity and purity of his thoughts. It would be truly be very pretty and amusing if our bodies were transparent, so that we could see one anothers sentiments and passions working as we see bees in a glass-hive."
