here it is

Pointing is something that strikes me as interesting. It’s the physical indication of connecting to the other person or thing that one is pointing to. Once one extends the arm and points at the person, object, or animal one is acknowledging and/ or the one who points is trying to convey a “point” about an object or pointing to the person to make them understand or become closer to them.
We see kids pointing to different object while they are learning words to connect the word to the object. When my cousin was three she would see a bug and point and say, “bug.” She was relating the insect to the word, its not the best subject, but she was making a connection.
It becomes impolite to point: To say, “Oh look at this its ugly,” and point or to point out the sins of others by pointing. By pointing out its just a way of illuminating by connection one idea to the subject. So now pointing is "connection" and pointing signifies the acknowledgment of a subject whether good or bad. However for centuries pointing has been used affectively in so many art forms and media to convey a connection whether good or bad.
Actually, I thought of this idea of pointing when I was studying my art history. Michelangelo, Sistine Ceiling, when god is reaching out to Adam and Adam is reaching to god but in a, “half ass way”: god has his whole body extended to Adam. God's hand is extended to the its outermost length. God wants to connect to Adam. But Adam just doesn’t care enough to connect to God. He is in a relaxed position: his hand is bent and his wrist is dropped a bit as he shiftless reaches his whole arm for god. So much is shown through the two’s pointing.
I can see it also in Caravaggio, Calling of Saint Matthew. Christ is pointing to Levi soon to be St. Matthew one of the apostles. Jesus’ wrist as he points is reminiscent to Adam’s hand in Michelangelo’s Sistine Ceiling. Jesus is shown as a “human” in a way of trying to connect to Levi by pointing to call him. But Jesus wants Levi to make the decision himself to become St. Matthew; its almost like Jesus is extending himself to Levi but its Levi’s right to accept the calling. Then I look at Levi and he is pointing at himself. He’s acknowledging himself as to whom Jesus is calling to and thus to became St. Matthew.
Of course even the media is calling the viewer. By having a person in the picture point physically out from the picture, the viewer has to acknowledge and connect to the picture because the picture is acknowledging and connecting to the viewer. I can see this in propaganda. Remember the war world two poster of big brother America pointing to the viewer. America acknowledges the viewer, citizens of the united states, and connects the viewer to them by pointing. The viewer will want to join the Army because of the connection America made through the poster.
What are the reasons why its impolite to point? Politicians point all the time so what makes a mother stop a child from pointing to the beggar. I suppose society has imposed on us that we can’t make an assumption about another person by pointing because it’s just that an assumption. By pointing a person brings to light something that they might see but don’t know the full knowledge of why that fault or other is there. Therefore its not moral to bring out that fault or distinguish that person. Pointing brakes a barrier that people put up because its about extension: extending your arm and your perception. Sometimes people don’t really have the right to extended there ideas or connect with the other because of privacy and decorum which each citizen has for the other. Still pointing, “drives the point home” we see it in so much in visual art because it stands for a symbol of braking boundaries through connection.
