QUOTE : If you summarily rule out any single sensation and do not make a distinction between the element of belief that is superimposed on a percept that awaits verification and what is actually present in sensation or in the feelings or some percept of the mind itself, you will cast doubt on all other sensations by your unfounded interpretation and consequently abandon all the criteria of truth. On the other hand, in cases of interpreted data, if you accept as true those that need verification as well as those that do not, you will still be in error, since the whole question at issue in every judgment of what is true or not true will be left intact.
