“We don't see things as they are, we see things as we are.”
The quote "We don't see things as they are, we see things as we are." is famous quote by Anaïs Nin (1903–1977), writer of novels, short stories, and erotica.
The Seduction of the Minotaur (1961); the documentation of the conflicting citations available on this page ( HNet http://h-net.msu.edu/cgi-bin/logbrowse.pl?trx=vx&list=H-Judaic&month=1108&msg=RizwZWCgeA8woVU9mNOEYQ) seems very thorough, and in the end attributes the quote to this novel, which includes the line:
Lillian was reminded of the talmudic words: "We do not see things as they are, we see them as we are."
With Nin's description of the statement as "Talmudic" it afterwards began to be attributed to the Jewish Talmud, without any cited version or passage.
Similar statements appear in You Can Negotiate Anything (1982) by Herb Cohen: "You and I do not see things as they are. We see things as we are"; and in Awareness (1992) by Anthony de Mello: "We see people and things not as they are, but as we are".
Another similar statement without cited source is also attributed to Nin https://web.archive.org/web/20050322041559/http://learn-gs.org/learningctr/tutorial/4.html: We see the world as "we" are, not as "it" is; because it is the "I" behind the "eye" that does the seeing.

Variant: We don't see people as they are. We see people as we are.

The Passionate State Of Mind, and Other Aphorisms (1955)
From a series of interviews with Marco Livingstone (April 22 - May 7, 1980 and July 6 - 7, 1980) quoted in Livingstone's David Hockney (1981) , p. 112
1980s
Context: When conventions are old, there's quite a good reason, it's not arbitrary. So Picasso discovered that, as it were, and I'm sure that for him that was probably almost as exciting as discovering Cubism, rediscovering conventions of ordinary appearance, one-point perspective or something. The purists think you're going backwards, but I know you'd go forward. Future art that is based on appearances won't look like the art that's gone before. Even revivals of a period are not the same. The Renaissance is not the same as ancient Greece; the Gothic revival is not the same as Gothic. It might look like that at first, but you can tell it's not. The way we see things is constantly changing. At the moment the way we see things has been left a lot to the camera. That shouldn't necessarily be.
