Regardless of whether other human beings are actually realor not is irrelevant, since we would still have to treat them as such. The consequences of not doing so would inevitably be similar one way or the other. For example, if I decided to go about shooting everyone at random, claiming that I am the only real human being on the planet, I would inevitably be thrown in a psychiatric prison.

We cannot come to know anything about ourselves, except through the mediation of another. (Sartre, pg....
