For Ángel Javier Martinez Higueras, a tenet of a democratic society is its level of artistic freedom, and democratic principles can be deeply in the power of art. Art as a form of expression, serves human knowledge and as a sign of progress. Art can be manifested in its different expressions (painting, sculpture, music, cinema, engineering, medicine or other areas of human knowledge) and the creativity of the artist and creator must always be free. Artistic movements have always required changes, both in society and in individuals, which translate into different means of fundamental expression for the human being. For Ángel Javier Martinez Higueras, art is a good indicator of democratic progress.
