A modern rendering of Sigmund Freud’s influential 1904 work On the Psychopathology of Everyday Life (Zur Psychopathologie des Alltagslebens), followed by his 1905 essay The Joke and Its Relation to the Unconscious (Der Witz und seine Beziehung zum Unbewußten). This unique edition brings together two of Freud’s most accessible yet profound explorations of metapsychology, examining how unconscious processes manifest in seemingly trivial aspects of daily life, such as slips of the tongue, forgetfulness, and humor. In On the Psychopathology of Everyday Life, Freud introduces the concept of the “Freudian slip,” demonstrating how unconscious thoughts and emotions influence even the most mundane actions. He argues that these seemingly accidental errors—such as forgetting names, misplacing objects, or misspeaking—are not random but reveal hidden desires, conflicts, and anxieties. Through detailed examples drawn from his own life and clinical practice, Freud illustrates how the unconscious mind intrudes into conscious behavior, offering a window into the deeper workings of the psyche. This work popularized the idea that “there are no accidents” in mental life, profoundly influencing both psychology and popular culture. The Joke and Its Relation to the Unconscious extends Freud’s analysis to the realm of humor, exploring how jokes provide a socially acceptable outlet for repressed thoughts and emotions. Freud argues that jokes, like dreams, rely on mechanisms such as condensation, displacement, and symbolism to bypass the censoring function of the conscious mind. He distinguishes between innocent jokes, which serve primarily to entertain, and tendentious jokes, which express aggression, sexuality, or critique. This essay not only sheds light on the psychological underpinnings of humor but also underscores the pervasive influence of the unconscious in shaping human behavior. This fresh, modern translation from the original German manuscript breathes new life into these historically significant works. Freud’s extensive writings have often been inaccessible to the general reader, and this edition seeks to bridge that gap by providing direct access to his original ideas. The Reader’s Edition introduces Freud’s work in context, with an illuminating Afterword that explains his philosophical project, situates it within the Modernist milieu, and explores its enduring impact on contemporary thought. The Afterword also examines the relationship and intellectual conflict between Freud and Carl Jung, particularly their differing views on the nature of the unconscious.
