No, I can know something and I can say I know something without making a knowledge claim....
I do not make a knowledge claim because I cannot prove what I know is true to anyone else.
Claims require proof. Since I cannot prove what I know is true I cannot claim it is a fact, but I can still know that what I believe is true since all knowledge is not based on facts that can be proven true. In
short, I do not claim that what I believe is true and expect others to believe it is true because I cannot prove it is true, but I can still say I know they are true because certitude is an inner knowing, and nobody can take my certitude away from me because it isn't theirs to take.
