The superficial goal of attempting to know other people can lead to a better Understanding of oneself.

We can't read minds, all we know of a person is what we hear from their lips, and what our minds fill in the blanks, they leave with.

In Not knowing others we give them aspects of ourselves, our biases or a reverse of our biases if they're someone you don't like.

Learning what assumptions you make, points to your own underlying structure.
