 Peirce too emphasizes the continuous character of perceptual experience, and adds that we directly perceive external things as external, as ‘other’, that we can perceive necessary connections between events, and that experience contains elements of generality (citing a picture of a connected series of circles which can be seen as a stone wall, in the manner of Wittgenstein’s famous duck-rabbit dual diagram). Around 1902–3, Peirce developed a complex and original theory of perception which combines a percept, which is entirely non-cognitive, with a perceptual judgement, which is structured propositionally and lies in the space of reasons. In this way he seeks to capture how perception is both immediately felt and truth-evaluable. In contrast to standard British Empiricist analyses of the relation between impressions and ideas, Peirce does not claim that a perceptual judgment copies its percept. Rather, it indexes it, just as a weather-cock indicates the direction of the wind. Although percept and perceptual judgment are intrinsically dissimilar, over time certain habits of association between the two are reinforced, leading them to (literally) grow in our minds and link with other habits. This enables percepts and perceptual judgments to mutually inform one another, to the point where every perception is fallible and subject to reinterpretation in the light of future perceptions (Legg 2017). The end result is that, as Peirce puts it, in stark contrast to the accepted understanding of experience as ‘given’: ‘[n]othing at all…is absolutely confrontitional’, although, ‘the confrontitional is continually flowing in upon us’ (CP 7.653).
