I've noticed oppression, though obviously unacceptable, has more often yielded the unparalleled art and expression that we hold highest. Its no secret that the Russians (though perhaps not Tolstoy specifically) haven't had the greatest of histories.
Hence, "I know why the caged bird sings."
There often is this illusion... perhaps due to the romantic notion that an artist must suffer to create an art of depth... but just how much truth is there to it? Looking at this century we discover how the Soviets and the Nazis effectively destroyed artistic cultures that were flourishing prior to their seizing power. The arts in Classical Greece, Rome, Renaissance Italy, 19th century France and England, etc... were born in wealthy, powerful nations where the arts were supported and valued. No culture is without censorship... whether explicit (imposed by church and state) or implicit (implied by self-appointed moral critics and the economy). But wealth and power and support for the arts should not be confused with liberal politics, peace and harmony:
