Art is the manipulation of our world to convey these concepts. The mediums, themselves, would be too numerous to list here. From paintings on a cave wall to music to virtual reality, humans have a highly developed artistic ability. Art also reflects the mood of a society. It is a good indicator of a healthy or decrepit culture.
All species communicate amongst themselves.
Humans have evolved with the ability to do so through a complex system of vocalizations, gesticulations, and expressions, which are able to transmit highly complex thoughts and feelings. The vocalizations, or languages, have co-evolved along with the human species. Much of the groups abstract reality is transmitted through language. Every language is a sophisticated means of labeling the reality for communication purposes. Language becomes a part of the mind, thus yoking the mind to the reality and the individual to the culture.
