Anthropology is, basically, the study of human kind in all aspects and offers a more historical and comparative approach. Alfred Kroeber says that anthropology is the most humanistic of the sciences and the most scientific of the humanities. It needs a lot of open mindedness to look and listen and also record and wonder things that we would not have been able to guess. It differs from sociology in the sense; anthropology is more of a comparative study of the human aspects.
It is also interesting to note that anthropology drives home the point that peoples of various countries, having different appearance with different languages and different kinds of life styles, can move along with each other peacefully. The study thus makes the world a safer place for human differences. There are many quotes on anthropology that give a clear idea of its study and send them to anyone who would find it useful.
