Pointing a finger may seem a rather simple action. You point a finger to show someone the road, or to point out something in the middle of many other things, or to draw attention to a stain on clothing. Usually words of explanation follow. Infants begin pointing after about 9 months of age and over a year before saying even very simple things. Pointing at something means that wo people are sharing attention on something of interest and not simply that they are simultaneously looking at something. Sharing ideas, aims and wishes is at the core of human relationships and is central to the formation of a culture. Only the human species has a sufficiently developed cognitive and social level to withstand the implications that a pointed finger carries. It serves to map what we have in common and create a communion of interests. It implies learning a technique that has to be mastered if we wish to speak about what we have in common. Sometimes pointing a finger is used to impose an idea on others and people of whatever culture or age immediately recognize the menacing meaning of a pointed finger.
