Since 'concepts' are closely bound up with language, concept art is a kind of art of which the material is language.
This quote highlights the intrinsic link between language and concepts, emphasizing that thought and artistic expression rooted in ideas are fundamentally shaped by linguistic structures. It suggests that our understanding and visualization of abstract ideas are mediated through language, making concept art a unique form of creative expression that relies on linguistic material. Recognizing this connection broadens the appreciation of how language influences not just communication but also creative processes, blurring the boundaries between verbal and visual art forms.
