How can a composer’s revisions to a piece be considered self-criticism?

In the context of musical criticism, a composer’s revision of their own work serves as a direct form of self-criticism because it acknowledges a discrepancy between the composer's original intent—the musical idea—and the actual written utterance.1

When a composer revisits a piece, they are essentially performing a "re-vision." This process involves returning to the score to modify the notes, rhythms, or structure to better align the final output with the intended musical meaning. By refining the work, the composer admits that the initial version failed to fully capture or communicate their vision, thereby acting as their own critic to ensure that every note is placed with precision and purpose. This practice reflects the principle that redundant or misplaced notes obscure musical meaning, and through revision, the composer strives to achieve a more perfect identity between their creative idea and its ultimate expression.1
