Analysis: Freud, Derrida and the Magic Slate

Do you remember playing with a magic slate as a child? Learn how Sigmund Freud uses this device to talk about the unconscious mind.

A Finnish Version of Freud's Wunderblock.

Do you remember this toy from your childhood? It’s charmingly called a “Magic Slate” or an “Etch-a-Sketch”. In German, the Wunderblock. I had a version of this toy as a kid. The novelty of the apparatus consists in the ability of the pad to retain impressions, such as drawings, and like a normal slate, the impressions can be erased, not by an eraser but by simply lifting the page. Presto. Freud and Derrida loved this thing. Freud liked it because the Magic Slate is a model for the human mind. Psychoanalysis! Derrida liked it because Freud's reading of it seems to suggest the unconscious is inhabited by writing and is prior to speech acts. Deconstruction!

Deconstruction!
The stylus is used to write, scribble, or draw on the transparent plastic sheaf which creates an impression on the middle thin layer. The magic slate I had as a kid was a simple plastic, red stylus. The slate itself was a flimsy plastic backing with the “magic sheaf” part lightly affixed to the backing.

When the sheaf is lifted, the thin papery layer which exists beneath it is erased of its impression. At the bottom, a resinous wax layer exists which retains etched into the resin the residuals, or traces of all the previous impressions.

Freud on the “Magic Slate”
Freud wrote a short seven-page essay called "A Note Upon The Mystic Writing Pad." He wrote the essay to explain his theory of memory via the working apparatus of the Wunderblock. The outer coating represents the protective layer of the mind. The layer protects the mind from too much excitation. Notice if the thin paper layer is torn or contaminated the Wunderblock ceases to work in the same way that trauma can irreparably damage the psyche. The stylus represents a stimulus from the outside world. The papery layer is the conscious mind and the wax resin is representative of the unconscious.

The memory of the present can be erased, but like the mind, retains the impressions in the unconscious. The Wunderblock can both destroy and create.

Freud thought the Magic Slate was the closest machine-toy resembling the human mind. The only difference between the Wunderblock and the human mind is the mind's waxy resin layer can come back and disrupt the psychic life. Notably in dreams and trauma.

Derrida On Freud
Derrida, in an essay called "Freud and the Scene of Writing" was astounded that Freud, as a metaphysical thinker, could have inadvertently stumbled upon a machine that is a metaphor for the techné (production) of memory.

Derrida wonders how Freud could have imagined the Wunderblock to represent the psychic life while not realizing that the fundamental essence of the toy, like the mind, is its reserve of graphical traces, not phonetic signifiers.

Luis Buñuel on Film and the Subconscious

To commemorate Luis Buñuel's death in 1983, here is an evocative piece he wrote about film and the subconscious:

In the hands of a free spirit the film is a magnificent and dangerous weapon. It is the superlative medium through which to express the world of thought, feeling, and instinct. The creative handling of film images is such that, among all means of human expression, its way of functioning is most reminiscent of the work of the mind during sleep. A film is like an involuntary imitation of a dream. Brunius points out how the darkness that slowly settles over a movie theater is equivalent to the act of closing the eyes. Then, on the screen, as within the human being, the nocturnal voyage into the unconscious begins. The device of fading allows images to appear and disappear as in a dream; time and space become more flexible, shrinking and expanding at will; chronological order and the relative values of time duration no longer correspond to reality; cyclical action can last a few minutes or several centuries; shifts from slow motion to accelerated motion heighten the impact of each.

The  cinema seems to have been invented to express the life of the subconscious, the roots of which penetrate poetry so deeply.
