On the human reality of other people:

If you deny any affinity with another person or kind of person,
if you declare it to be wholly diferent from yourself - as men
have done to woman, and class has done to class, and nation
has done to nation - you may hate it or deify it; but in either
case you have denied its spiritual equality and it's human reality.
You have made it into a thing, to which the only possible relationship
is a power relationship. And thus you have fatally impoverished your
own reality. You have, in fact, alienated yourself.

Urusla K. Le Guin - The Language of the Night (1979)
