"My paintings are not about what is seen. They are about what is known forever in the mind"

Agnes Martin's quote talks to the idea that art is not just about what is seen, however also about what is known. She recommends that her paintings are not just about the physical objects or scenes that are portrayed, however also about the intangible ideas and feelings that are kept in the mind. This might be interpreted as a reference to the power of art to stimulate memories, feelings, and concepts that are deeply personal and distinct to each individual. Martin's quote also speaks to the idea that art can be a form of self-expression, permitting the artist to interact their innermost thoughts and sensations. Ultimately, Martin's quote suggests that art is a powerful tool for conveying the intangible aspects of the human experience.
