It's a definition thing. Change the words to suit your own preferences.

I trust you are not recommending this. The conventional understanding is that knowledge is true, justified, belief.

I just didn't want to get into a discussion over semantics. All dictioaries are eventually circular, "knowledge" "proof" "belief" "faith" do not have universally agreed interpretation -- see posts above for more wordy discussions where people were working toward establishing a mutually agreed definition for "belief."
