It is hereby declared to be the policy of the State to join with private patrons and with institutions and professional organizations concerned with the arts to insure that the role of the arts in the life of our communities will continue to grow and play an ever more significant part in the welfare and educational experience of our citizens. It is further declared that all activities undertaken by the State in carrying out this policy shall be directed toward encouraging and assisting rather than limiting the freedom of artistic expression that is essential for the well-being of the arts.
