Rene Magritte famously painted an image of a pipe with the words "Ceci n'est pas une pipe." below it. This translates from French to "This is not a pipe". The painting, titled "The Treachery of Images" (or sometimes translated as "The Treason of Images"), serves to illustrate that an image of a thing is not the thing itself. An image invokes in our minds the memories and experiences we associate with the image, thus every work of art is different to each viewer who brings with them their own unique perspective. A work of art is not complete until it is viewed. It has no meaning until an observer ascribes one to it. When an artist creates a piece, he or she may be trying to communicate a certain message to the viewer, but in the end the meaning is completely out of the creator's hands.
If you see something depicted that offends you, you have no one to blame but yourself.
My work is often "erotic". I am a Fetish Artist, and I create work that is sexually explicit in nature. I do not shy away from displays of the human body, genitalia, or the sex-act. All of these things are common to the human experience; we've all see it and the vast majority of us have indulged in it. Art is a reflection of life, and these things are also life. Yet, many people are embarrassed to see a depiction of what I consider the power and beauty of the female being and are often reproachful about my work or the work of artists like myself.
But, as you see in this image, this is not fellatio. It is an image of what may be a woman's mouth. The image of the mouth is displayed open, and from the image of the mouth there appears to be an empty space matching the image of the opening and extending to the far edge of the image. I left that space intentionally blank. You fill it in with your mind. You bring to the image the missing piece. You complete the image in any manner you choose. If you are offended, you have no one but yourself to blame.
The space could be a depiction of air, fire, or even a white laser ushering forth from the mouth. It could be a depiction of words, singing, or the spirit. It could be any of these things, but if your mind put something else there, something more profane, then you are a pervert. That is not a condemnation, I think we all need to embrace our inner pervert and be a little less prudish and a little more appreciative of the simple joys our bodies make available to us. Sadly, even the idea that you are a pervert will be distressing to some. You have been programmed well.
