His work delves into abstraction, exploring the ineffable beyond logical propositions through artistic forms. He views art not as a proposition that asserts a logical judgment, but as a medium to express the unspeakable. Rejecting established principles, Lee layers the canvas with the unknown, uncharted mysteries, emphasizing immediate, intuitive insights rather than fixed concepts.

Artist Taeryang Lee's major series, Propositional Forms and Non-Landscape Mountain, represent the artist’s signature approach. They reverse traditional logical propositions and landscape paintings, presenting a structure of a new dimension. The traces created by various abstract brushstrokes emphasize the artist’s immediate, painterly insights, forging unique layers that are neither being nor non-being, without any definite markers.
