"Any material may be used but the theme is the same and the response is the same for all artwork... we all have the same concern, but the artist must know exactly what the experience is. He must pursue the truth relentlessly"

In this quote, Agnes Martin is emphasizing the value of the style and reaction in artwork. She recommends that while any material can be used to produce art, the underlying style and reaction ought to remain constant. This indicates that no matter the medium or method, the artist's message and objective need to remain the same. Martin likewise highlights the artist's responsibility to accurately communicate their experience and pursue the reality in their work. This requires a relentless pursuit of understanding and expression. Eventually, Martin recommends that all artists share a common issue and it is their task to communicate it authentically through their art.
