Context: <response>: In higher organisms (like people), these two modes of perception combine into wetin Whitehead dey call "symbolic reference", wey join appearance with causation for one process wey dey so automatic say both people and animals dey find am hard to avoid am. For example, Whitehead use the example of person wey see chair. Ordinary person go look up, see colored shape, and immediately believe say na chair. But, artist, Whitehead suppose, "fit no just believe say na chair", but instead "fit just stop for beautiful color and shape." Dis one no be normal human reaction; most people dey put objects for categories out of habit and instinct, without even think about am. Also, animals dey do the same thing. Using the same example, Whitehead talk say dog "for don act immediately on top say na chair and for don jump on top am as e dey use am like that." For this symbolic reference na combination of pure sense perceptions on one hand and causal relations on the other, and na the causal relationships dey dominate the more basic mentality (as the dog show), while na the sense perceptions dey show say na higher grade mentality (as the artist show).
