In a dream, a single idea or image may represent the nodal point at which a number of chains of associations or ideas intersect, and can thus be a condensation of both their multiple unconscious meaning and their quota of affect or emotional charge.
Condensation, in contrast, operates by bringing intensities together. When two chains of association intersect, it assigns to the common link the sum of the intensities of the two intersecting chains.
By displacing the intensities of several chains to their common link, condensation makes it possible to represent all of the chains by a single link.
Hence, there is an economy of means that contributes to censorship. As a result, when one link takes the place of several chains, this makes it more difficult to read through to the wish corresponding to those chains.
Condensation thus has an indirect effect on the figural content of representations.
It does not create chimeras that bring together in one element the attributes of others.
When explaining the effect of condensation, Freud used the metaphor of italics. A representative link whose intensity has been reinforced by condensation has a status comparable to that of a word in italics in a text. This metaphor calls for two remarks. First, the intensity added to a fragment of a representation through condensation makes it possible, like italics, to stress the importance of the representation. This added intensity indicates at the manifest level that the representation stands for the different latent chains intersecting at the link. Second, typographical emphasis warps the texture of a text and invites us to look for links other than those offered by successive statements. Typographical emphasis is an invitation to abandon linearity and search for the dreamer's associations.
The notion of intensity is complex. The term indicates the psychic interest of a particular idea. But we may well ask whether this interest should not be extended to the affect associated with each chain of associations or the instinct that determines each association.
Although Freud studied condensation particularly in relation to dreams, especially in The Interpretation of Dreams, he also describes the effect of this process in other manifestations of primary-process thinking, such as jokes, forgetting names, slips of the tongue, and symptoms. In these latter domains, however, it is sometimes quite difficult to distinguish between condensation and overdetermination. In both cases, as the result of a transformation, a representation substitutes for more elaborate thought content. Both processes seem to proceed by increasing intensity, that is, by economic modification, and this results in the reorganization of the thought content. But whereas condensation can be viewed as a sum of intensities relative to forces acting in the same direction, overdetermination appears more as an appropriation of content by heterogeneous if not antagonistic forces.
In fact, the content of an overdetermined representation acts as a fulcrum for opposing logics and conflicting systems (such as the preconscious and the unconscious). A thought content (or representation) resulting from the interaction of forces pushing for the fulfillment of an unconscious wish and forces opposing it (the censor) is a good example of overdetermination but not of condensation, since the censor is not part of the latent dream thoughts. However, as soon as the signifying element begins to represent conflict (as in the case of a symptom), the difference between condensation and overdetermination is more difficult to establish.
