Obama's Oval floor piece contains five quotes from past presidents and Martin Luther King Jr.
From The Daily Caller, here are the five quotes:
•“The Only Thing We Have to Fear is Fear Itself” – President Franklin D. Roosevelt
•“The Arc of the Moral Universe is Long, But it Bends Towards Justice” – Martin Luther King, Jr. (this is the controversial quote)
•“Government of the People, By the People, For the People” – President Abraham Lincoln
•“No Problem of Human Destiny is Beyond Human Beings” – President John F. Kennedy
•“The Welfare of Each of Us is Dependent Fundamentally Upon the Welfare of All of Us” – President Theodore Roosevelt
Here is the original quote by Theodore Parker. In Parker's book "Of Justice and the Conscience" (1853) he asserted: "I do not pretend to understand the moral universe; the arc is a long one, my eye reaches but little ways; I cannot calculate the curve and complete the figure by the experience of sight; I can divine it by conscience. And from what I see I am sure it bends towards justice."
According to Wikipedia, Martin Luther King Jr. echoed the same sentiments of Parker but only more succinctly. Martin Luther King Jr. did indeed say "The arc of the moral universe is long, but it bends towards justice".
I do agree that the Bush-era rug displayed an air of optimism whereas the new rug that Obama chose for the oval office is quite drab and honestly IMO displays pessimism. Bush endeared, loved, and raved about his rug since his wife Laura designed it. His rug displayed what looked like rays of sun.
Here is a picture of Bush's Oval Office rug:
