Shakespeare's Sonnet 105 famously applies that janus-faced word, fair :

Let not my love be called idolatry,
Nor my beloved as an idol show,
Since all alike my songs and praises be
To one, of one, still such, and ever so.
Kind is my love to-day, to-morrow kind,
Still constant in a wondrous excellence;
Therefore my verse to constancy confined,
One thing expressing, leaves out difference.
Fair, kind, and true, is all my argument,
Fair, kind, and true, varying to other words;
And in this change is my invention spent,
Three themes in one, which wondrous scope affords.
Fair, kind, and true, have often lived alone,
Which three till now, never kept seat in one.

A brief summa. Reminds me of this passage I just read in PK Dick's Divine Invasion :

"A man came to the great Rabbi Hillel - he lived in the first century, C.E. - and said, 'I will become a proselyte on the condition that you teach me the entire Torah while I stand on one foot.' Hillel said, "Whatever is hateful to you, do not do it to your neighbor. That is the entire Torah. The rest is commentary. Go learn it.'"
