“When a person hasn’t in him that which is higher and stronger than all external influences, it is enough for him to catch a good cold in order to lose his equilibrium and begin to see an owl in every bird, to hear a dog’s bark in every sound.”
—Anton Pavlovich Chekhov (1860–1904)
“Nor stony tower, nor walls of beaten brass,
Nor airless dungeon, nor strong links of iron,
Can be retentive to the strength of spirit.”
—William Shakespeare (1564–1616)
