It seems as if there is a tendency to use words like, knowledge, belief, faith, and reason, as if they have real fixed meanings. I think we all understand these words in subtly and sometimes not so subtly different ways. Not only do different people relate to these words differently but I think individuals tend to fluctuate in how they understand the meanings.
"Beautifully taught is the Lord's Dhamma, immediately apparent, timeless, of the nature of a personal invitation, progressive, to be attained by the wise, each for himself." Anguttara Nikaya V.332
