Can’t I reasonably use myself as a model for all the rest? It would be not so much a case of knowledge as of a hypothesis or conjecture, but it perhaps it is a reasonable conjecture to make. This is called the argument from analogy to the existence of other minds.
Its reasonable that since i cme from my parents, i am like them. Thus they must too have minds like mine. Likewise all people are related having arose from apes and subsequent presursor species some few hundres years ago. We all ought to have similar minds.
