Holzer's conception of language as art, in which semantics developed into her aesthetic, began to emerge in New York. The Whitney program included an extensive reading list incorporating Western and Eastern literature and philosophy. Holzer felt the writings could be simplified to phrases everyone could understand. She called these summaries her "Truisms" (1978), which she printed anonymously in black italic script on white paper and wheat-pasted to building facades, signs, and telephone booths in lower Manhattan. Arranged in alphabetical order and comprised of short sentences, her "Truisms" inspired pedestrians to scribble messages on the posters and make verbal comments. Holzer would stand and listen to the dialogues invoked by her words.
