Anthropology is the holistic "science of man", a science of the totality of human existence. The discipline deals with the integration of different aspects of the social sciences, humanities, and human biology. In the twentieth century, academic disciplines have often been institutionally divided into three broad domains. The "natural sciences" seek to derive general laws through reproducible and verifiable experiments. The "humanities" generally study local traditions, through their history, literature, music, and arts, with an emphasis on understanding particular individuals, events, or eras. The "social sciences" have generally attempted to develop scientific methods to understand social phenomena in a generalizable way, though usually with methods distinct from those of the natural sciences.
