Famous quotes containing the word external:

    “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)
