How else does one discover one's roots, one's purpose and one's future if not through storytelling? How does one pass on a people's culture if not through art and what else can express that which is inexpressible, whether it be love, pain, despair, peace, desire and hope, when one has run out of political rhetoric and the heart's emotion is too great to bear, except through music?
Governments and ideologies that demote the arts do so for a very good reason. Not because medicine, agriculture, maths or science is more important but because the arts keep people human. They are the expression of our souls. The danger of the arts is that when people express their souls, when they imagine life beyond the confines of the regime's ideology, they will begin to think for themselves, to imagine and create a life without the regime or the ideology. They will yearn for, strive for and eventually bring into being a better life. A life of freedom. A government or ideology which doesn't allow creative thought and expression is one built on hatred and fear. And the only natural outcome of that is death. Someone once said, "Governments that burn books, will soon be burning people."
