Characterized by a search for meaning, Hirsch's oeuvre connects psychological, scientific, and philosophical implications of form, bringing together ideas in art, science, ecology, and human consciousness.

The artworks in multiple and mixed media provide an evolving history of Hirsch's ideas and craft as they illustrate the progression of her original research on the origin of all alphabets. Her elegant theory about five fundamental shapes in nature that reflect forms of neurons and neural processes of perception and cognition as the source of all letterforms in alphabets ancient to modern has gained acceptance in scientific circles. Her evidence shows that while cultures and languages bring unique beauty and richness to the world, we, as humankind, are more alike than different.

Since the 1980s, Hirsch has also been a pioneer in the field of mind/body healing, developing a type of visualization practice that serves as an instrument toward wellness. By organizing seemingly disparate information into a far-reaching scientific theory, Hirsch is recognized internationally for these techniques and has advanced healing practices through the arts.

Archaeology of Metaphor connects the artist's visual themes to her philosophy and ideas, simultaneously encouraging greater awareness of pattern recognition, social dynamics, and interconnectedness.
