"Culture" is difficult to define. Here are two broad, overarching definitions:
- As a global sociological concept: the totality of socially transmitted behavior patterns, arts, beliefs, institutions, and all other products of human work and thought, built up by a group of human beings defined by a particular common characteristic (e.g. by socio-geographical, ethnic, or age) and transmitted from one generation to another. e.g. Western culture, Russian culture, youth culture.
- As a local personality trait: the intellectual quality in a person or society that arises from a concern - developed through training or education - for what is regarded as excellent in arts, thought, scholarly pursuits, and so on. e.g. "the sitar player and Ancient History teacher was a cultured woman."
So you can now imagine that "culture" is something enriching, specific, a process of identification, never static but always evolving with time, and inherently beautiful in our world.
