PHRASE-I never met a man who was not in some way my superior

Does anyone know where the phrase "I never met a man who was not in some way my superior". I think it may be Lincoln.

Quote: Ralph Waldo Emerson
"Every man I meet is in some way my superior. "
I will once again recommend to everyone Emerson's Journals. Good reading.

There is an episode of All in the Family which contains the quote: "Every man is my superior in that I may learn from him".
Is this a real quote? Who said it?
