For Reid, the perception of the child is different from the adult, and he states that man must become like a child to get past the artificial perception of the adult, which leads to Hume's view that what we perceive is an illusion.
Reidi arvates on lapse taju erinev täiskasvanu omast ning ta leiab, et inimesed peaksid muutuma lapselikemaks, et saada üle täiskasvanu kunstlikust tajust, mis viib Hume’i vaateni – see, mida me tajume, on illusioon.
