Our Sensations are not adequate in Knowledge.

"The main and more philosophic reply to Reymond's widely accepted view, that sensations must play a role in the learning process, is directed against two words, sensation and role. Clark's reply to both is the same, viz., they convey no meaning. Like nearly all, one could actually say all, Clark's empirical critics within the evangelical movement, Reymond refuses to define sensation. If it be defined as Aristotle and John Locke defined it (though these two did not completely agree) there is no such thing. Augustine made that quite clear. We never see a poem with our eyes nor do we ever hear a tune with our ears. A single note may be a sensation, but it is not a tune. In ordinary parlance we must hold in mind remember, compare, judge a series of notes in order to 'hear' a tune. Similarly, no one has ever seen a tree. Since Clark was so deeply influenced by Augustine, his critics are remiss in not meeting Augustine's position." - Clark Speaks from the Grave
