“Art is on the side of the oppressed. Think before you shudder at the simplistic dictum and its heretical definition of the freedom of art. For if art is freedom of the spirit, how can it exist within the oppressors?”

Context: I can find inspiration from the Renaissance to the contemporary artists, but definitely the most influential movement in my career has been Street Art. The importance of Street Art comes from the fact that this art is available to everyone anywhere, is made from any media using any technique. Street Art lets you do whatever you want in the way you want and do it without asking anybody. This freedom is what makes Street Art unique.

Context: Whether or not we can get together, remember well that art “lives” where absolute freedom is. With all the training thrown to nowhere, with a mind (if there is such a verbal substance) perfectly unaware of its own working, with the “self” vanishing nowhere, the art of JKD attains its perfection.
