The examples that work for me as examples that look like knowledge, and as examples that don’t look like knowledge, are those expressed in Paragraph 563 of On Certainty, a publication of material written on twenty sheets of foolscap, and written in small notebooks, that Dr. Ludwig Wittgenstein wrote in the last year and a half of his life:

563. “One says ‘I know that he is in pain’ although one can produce no convincing grounds for this.—Is this the same as ‘I am sure that he…’?—No. ‘I am sure’ tells you my subjective certainty. ‘I know’ means that I who know it, and the person who doesn’t are separated by a difference in understanding. (Perhaps based on a difference in degree of experience.) “If I say ‘I know’ in mathematics, then the justification for this is a proof.

“If in these two cases instead of ‘I know’, one says ‘you can rely on it’ then the substantiation is of a different kind in each case. “And substantiation comes to an end.”
