A drawing is essentially a private work, related only to the artist's own needs; a 'finished' statue or canvas is essentially a public, presented work - related far more directly to the demands of communication.

John Berger's quote highlights the distinction between private and public forms of artistic expression. He suggests that a drawing is an intimate, personal endeavor, serving the artist's own needs rather than aiming for external communication. The artist may use a drawing as a tool for exploring ideas or emotions, with little concern for how others perceive it. The purpose of the drawing is not to communicate a finished idea, but to serve as a reflection of the artist's inner world.

In contrast, a finished statue or canvas is a public artwork, created with the intention of being shared with others. Such works are often designed to convey a specific message, evoke certain emotions, or communicate an idea to a wider audience. The artist must consider the demands of communication, as the artwork is meant to be experienced and interpreted by the public.

Berger's distinction between private and public works of art reflects a broader commentary on the role of art in society. While drawings may be created for personal exploration, more formal artworks like sculptures or paintings are often influenced by societal expectations and the desire to communicate with a broader audience. This contrast underscores the differing purposes that art can serve, from the deeply personal to the outwardly expressive.

The quote suggests that while art can serve multiple purposes, its form and intent shift based on the artist's relationship with the audience. Drawings are personal and raw, whereas finished artworks are carefully crafted to fulfill a communicative role, demonstrating the dynamic and evolving nature of artistic creation.
