demonstrative way of givenness / Peacocke: here, now, this is also non-linguistically possible - ostentatiously: "Today", descriptively: "the day after today" - instead of phrase and language only capacity for different reaction
Summary / Peacocke: what is determinative of a given demonstrative type, is the pattern of evidence or prior conditions so that judgments that contain tokens of this type, must be sensitive for it - the constitutive role that is associated with this type, must capture this complex pattern of evidential sensitivity.
