What does holism refer to?

Holism in anthropology is the view that all aspects associated with human beings are interconnected. This concept holds that the mind, body, and the environment are all interrelated, and one cannot do without the others. Therefore, holism suggests that aspects such as society, religion, politics, and culture are equally as important to human beings as their physical and mental well being. These factors are considered essential because they help in shaping people’s characters and personalities.
Holism connects human behavior to the environment and society. For instance, increased violent crime rates in a given community could be attributed to high levels of unemployment. Holism is evident in anthropology, as that various topics are analyzed when studying human beings. For example, anthropology has multiple sub-disciplines, such as archaeology and cultural anthropology, which contribute to the overall understanding of human beings.
