 Finally, regarding (3), as mentioned, perception is an activity of “taking up” by organisms already functioning in situations, not an instant, passive apprehension of stimulus. As such, there are always selective adjustments; quick or slow, they always take some time. Perception is never naïve, never a confrontation with some “given” content already imbued with inherent meaning. Long before Wilfred Sellars (see  entry on Sellars)  dismissed the passive-perception-encounter as modern empiricism’s “Myth of the Given”, Dewey rebuked such claims. All seeing is seeing as—adjustments within larger acts. Over time, these habits of adjustment change and, as a result, what is perceived can also shift; subsequent selections and interpretations are modified (DE, MW9: 346).
