 Prehension is, however, intimately related to knowledge. Broad asks us to consider a subject “which has appropriate general concepts and is capable of making judgements and knowing facts”. Suppose this subject prehends a certain particular object as red. Then this “suffices to enable him to know the fact that it is red. Whether he does or does not actually contemplate this fact at the time depends on various contingent circumstances” (1952a, p. 14; Broad’s  emphasis).[4]
