[[Need]] is a purely [[biological]] [[instinct]], an appetite which emerges according to the requirements of the organism and which abates completely (even if only temporarily) when satisfied. The [[human]] [[subject]], being born in a state of [[helplessness]], is unable to [[satisfy]] its own [[need]]s, and hence depends on the [[Other]] to help it [[satisfy]] them. In order to get the [[Other]]'s help, the [[infant]] must express its [[need]]s vocally; need must be articulated in [[demand]]. The primitive [[demand]]s of the [[infant]] may only be inarticulate screams, but they serve to bring the [[Other]] to minister to the [[infant]]'s [[need]]s. However, the [[presence]] of the [[Other]] soon acquires an importance in itself, an importance that goes beyond the [[satisfaction]] of [[need]], since this [[presence]] [[symbolize]]s the [[Other]]'s [[love]]. Hence [[demand]] soon takes on a double function, serving both as an articulation of [[need]] and as a [[demand]] for [[love]]. However, whereas the [[Other]] can provide the [[object]]s which the [[subject]] requires to satisfy his [[need]]s, the [[Other]] cannot provide that unconditional [[love]] which the [[subject]] craves. Hence even after the [[need]]s which were articulated in [[demand]] have been satisfied, the other aspect of [[demand]], the craving for [[love]], remains unsatisfied, and this leftover is [[desire]].
