Thinker was inspired by the Metteyya Buddha image of Eastern culture. With concise, light, unhurried but powerful line transition, Lee Kuang-Yu depicts the expression of a person deep in thought. The work also borrows the creative meaning of “between the real and the incorporeal” of eastern art, using a plate-shaped structure to form a spatial style in which real and unreal are intertwined. No matter where he is, the thinker merges into the surrounding space, the space around becomes his own spiritual world, like entering a place with no one else during deep contemplation. And it is the essence of “All reality is a phantom, and all phantoms are real.”
