 The first stage of the dynamic genesis of sense, the primary order of language, is found in the newborn infant. Deleuze draws from a tradition of developmental psychology whose insights are expressed in the vivid image of Daniel N. Stern: the infant’s experience is a kind of human “weatherscape,” made up entirely of sequences of risings and fallings of intensity—the jolting of a bright light or a sharp noise, the calming of a voice, or the explosive breakout of a storm of hunger (The Interpersonal World of the Infant, 1985). Deleuze will draw upon the writings of the French writer Antonin Artaud and call this life of intensities-in-motion the “body without organs.” This primary order of language (pure Noise as a dimension of the body) constitutes a first type of nonsense. But in the midst of this world of intensities, there also appears a particular noise: the sound of the child’s parents, or other adults. Long before the infant can understand words and sentences, it grasps language as something that pre-exists itself, as something always-already there, like a Voice on high. But for the child the Voice has the dimensions of language without having its condition. (Adults have the same experience when they hear a foreign language being spoken.) For the infant to accede to the tertiary arrangement of language (denotation, manifestation, signification), it must pass through its secondary organization, which is the production of the surface dimension of sense. How does this construction take place? From the flow of the Voice, the child will extract differential elements of various orders (phonemes, morphemes, semantemes) and begin to synthesize them into diverse series.
