Remarks by Douglas B. Rasmussen
"We do not ever really have to wonder whether we are in cognitive contact with reality—that is a given. It should be noted that the Aristotelian approach to this issue does not confine knowledge to strictly that of knowing propositions. I have used the term ‘cognition’ here to indicate an intentional union or contact with reality. This certainly includes but is not confined to the propositional."
