Projection, broadly defined, refers to the act of casting an image or idea onto a surface, yet it also holds deep psychological and philosophical significance. In literature and thought, it represents the assignment of one’s internal struggles or characteristics to external entities, as Helen Schucman demonstrates in A Course in Miracles, where it warps perception and sustains self-deception.
William James examines its function in visual awareness, while Joris-Karl Huysmans underscores its persuasive power in argument. From Samuel Johnson’s critiques of logical errors to John Dewey’s study of belief formation, projection appears as a framework through which human cognition, defense strategies, and social interactions are viewed, highlighting its dual function as both a perceptual instrument and a psychological safeguard.
