A healthy, dose of guilt never hurt anybody. It’s what civilization was built on, guilt. A highly underrated emotion. - Barack Obama

And I think one of the things that's important for bringing about further progress is that we listen to each other and we understand our differences. I don't think it's necessary for us to all speak one language, or all have the same foods, or all have the same customs. But I do believe that there are some universal principles that are important. I believe that the most important principle is a very simple one that is at the heart of most of the world’s great religions, which is treat somebody the same way you’d want to be treated. And if you start with that basic premise, then we will continue to make progress. But I also think that in order for us to make progress, we have to have that fellow feeling and we have to combine that with the use of our brains and reason, and our intellect. […] That requires not just a strong heart, but also using our heads. And if we do those two things, then I feel confident that we'll make progress.

In my second inaugural address, I said that if we are truly created equal, then surely the love we commit to one another must be equal as well. It is gratifying to see that principle enshrined into law by this decision.

Dignity will win -- because every human being is born equal, with free will and inalienable rights. And any regime or system of government that tries to deny these rights will ultimately fail and countries that uphold them will only grow stronger.
