How projecting your own feelings into objects explains everything from art to optical illusions

In short: Theodor Lipps was a titan of German philosophy who redefined how we perceive the world. By popularizing the concept of empathy as a physical projection of the self into objects, he bridged the gap between psychology and aesthetics, leaving a profound mark on thinkers ranging from Sigmund Freud to Edmund Husserl.

Born in 1851, Theodor Lipps became one of the most influential German professors of his era. He is best remembered for formalizing the concept of Einfühlung, or empathy, which he defined as the act of projecting one's own internal state onto an object of perception. While he adapted this notion from Robert Vischer, Lipps stripped away the earlier mysticism, grounding the idea firmly within the realm of scientific psychology. For Lipps, empathy was not merely a passive observation but an active, inseparable engagement where the observer’s pleasure and the object itself merge into a single experience.

Lipps’s intellectual reach was vast. He was a staunch advocate of psychologism, arguing in his 1893 work, Logik, that logic should be treated as a psychological discipline—essentially the mechanics of how the mind functions—rather than a set of ethical rules for thinking. This perspective deeply influenced his contemporaries, including Sigmund Freud, who adopted Lipps’s theories on the unconscious and the nature of humor. Lipps also applied his rigorous experimental approach to visual perception, identifying geometric-optical illusions where the human mind compensates for kinked lines, causing parallel segments to appear tilted.

In his later years, Lipps’s influence shifted as he began to incorporate ideas from Edmund Husserl. This transition created a fascinating intellectual friction; some of Lipps’s own students, dissatisfied with his earlier psychologism, joined forces with Husserl’s followers to pioneer the phenomenology of essences. Figures like Moritz Geiger and Paul Ferdinand Linke emerged from this environment, carrying the torch of Lipps’s inquiries into the meaning of empathy into a new philosophical era. Despite these shifts, Lipps remains a pivotal figure, serving as a primary link between the nineteenth-century focus on the psyche and the twentieth-century development of phenomenological thought.
