 Thus consciousness is a function of the scope of attention, which may be broader (as perception) or narrower (as  apperception[34]  ). Apperception, in turn, may either actively select and focus upon a perceived representation, or it may passively find certain representations suddenly thrusting themselves into the center of attention (PP II: 267; 562). There is no distinct boundary between the perceived and the apperceived, and Wundt’s analogy may be misleading (cf. esp. PP II: 268) to the extent that it gives the impression of two separable forms of attention able in principle to subsist together simultaneously (that is, apperception focusing upon a point in the perceptual field while that field continues to be perceived). No: perceptive attention becomes apperceptive attention just as it focuses more strenuously, constricting the perceptive field. The more it contracts, the “brighter” the representation appears, now becoming the focal point of apperception as the fringes of the perceptual field retreat into “darkness” (PP II: 268). For Wundt, the distinguishing feature of the apperceptive focus is that it “always forms a unitary representation”, so that a narrower focal point (or rather, the focal “field” [PP II: 268; 477]) results in a correspondingly higher intensity of attention (PP II: 269). Hence
