  In the canonical literature conceptual proliferation is associated  with sensory activity rather than consciousness [see Samyutta  Nikāya, I, 100, IV, 52; Majjhima Nikāya, I,  65]. These proliferating tendencies, which are sustained by a  constant flow of sense impressions, give rise to the common sense  conceptual schema that informs our ordinary, habitual coping  practices. Thus cognition, in its perceptual aspect, has a dual form: subjectively, it discloses a bare consciousness that merely attends  to the flow of sensations; objectively, it corresponds to each  specific domain of empirical awareness: visual objects to visual  awareness, sounds to auditory awareness, etc.
