Graph of desire

Graph of desire is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Graph of desire rather than just read about it. In short: The graph of desire (French: graphe du désir) is a conceptual tool in Lacanianism. History Lacan devised numerous quasi-mathematical diagrams to represent the structure of the unconscious and its points of contact with empirical and mental reality.

Key takeaways

  • Graph of desire belongs to engineering; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Graph of desire to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Graph of desire from memory before moving on to harder problems.

Reference excerpt

The graph of desire (French: graphe du désir) is a conceptual tool in Lacanianism.

History Lacan devised numerous quasi-mathematical diagrams to represent the structure of the unconscious and its points of contact with empirical and mental reality. He adapted figures from the field of topology in order to represent the Freudian view of the mind as embodying a "double inscription" (which could be defined as the ultimate inseparability of unconscious motivations from conscious ones).

Graph The graph of desire was first proposed in a 1960 colloquium, and was later published in the Ecrits. It depends on ideas developed originally in Lacan's Schema R, a graph in which fundamental organising structures of the human mind are shown in a schematic relationship to the domains or "orders" which in turn structure human reality: the Imaginary, the Symbolic and the Real. The graph of desire is a "flattened" representation of a signifying chain as it crosses a pathway Lacan called a vector of desire. It appears as two curved lines which cross one another at two separate points. Each line has a symbolic meaning.

Elements of the graph The signifying chain begins in a linguistic sign (S) and progresses to a signification (S'), or a linguistic meaning. It can be expressed sequentially and has a duration. The vector of desire is a representation of the volition and will of the split or barred subject ($). Unlike the signifying chain, the vector of desire is expressed metaphorically, and has no duration. It is necessary to bear in mind the special conception of the subject Lacan means by the $ symbol. The barred subject is the internally conflicted result of the processes of individuation that begin in infancy. In Lacan's account of individuation, the infant must respond to the loss of symbiosis with the mother by creating a symbol of this lack. In doing so the infant is constrained by the always-already present structures of a natural language. There is a certain relief in the summoning of a symbolically present "mother", but the experience of the mother who returns to the infant as someone-signified-by-the-word-"mother" is nevertheless one of absolute, irremediable loss. Mother—and the world—is now mediated by the Symbolic order and the exigencies of language. With this in mind, the crossing of the two pathways in the graph of desire can be understood to connote interference and constraint. Desire for the primordial object is not fulfilled except through the constraints of the signifying chain. The vector of desire is metaphorical, substituting various objects for the absolutely lost primordial one, and irrupting into language without regard for the passage of time, or for the particular human relationship through which the vector moves. Finally, the points at which the vector of desire and the signifying chain cross can be seen as instances of Freudian double inscription. The "conscious and unconscious" significance of an act or utterance are one and the same, and each constrains the other.

Worked examples

Example 1 — a first encounter with Graph of desire

Start with the simplest possible case. Write down what Graph of desire claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Graph of desire before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Graph of desire ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Graph of desire

In research
Graph of desire appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Graph of desire in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Graph of desire is common in secondary-school and first-year university syllabi. It links to neighbouring topics Jacques Lacan, Post-structuralism, Psychoanalytic terminology, so understanding it makes those chapters shorter.
In everyday life
Look for Graph of desire outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Graph of desire in simple terms?

The graph of desire (French: graphe du désir) is a conceptual tool in Lacanianism. History Lacan devised numerous quasi-mathematical diagrams to represent the structure of the unconscious and its points of contact with empirical and mental reality.

Why does Graph of desire matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Graph of desire?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
