Famous quotes containing the word internal:

    When a person doesn’t understand something, he feels internal discord: however he doesn’t search for that discord in himself, as he should, but searches outside of himself. Thence a war develops with that which he doesn’t understand.
    Anton Pavlovich Chekhov (1860–1904)
