 Drives are characterized by their aims – for instance, the aim of the shopping drive is having lots of stuff – and they generate objects (typically, objects of desire), which are formally a very different matter. When an object is attained (continuing the illustration, when you bring home that gewgaw from the craft fair), the desire for it evaporates, and you are satiated; but after a while, the drive generates a new object (now a garment, which seems to you a steal at 30% off). Drives working this way, that is, generating one object of desire after another, can be characterized more deeply as directed toward encountering and overcoming resistance.
