At one point, he spoke about the idea of America:
Eight years earlier, he gave the commencement address at the University of Pennsylvania:
Me, I'm in love with this country called America. I'm a huge fan of America, I'm one of those annoying fans, you know the ones that read the CD notes and follow you into bathrooms and ask you all kinds of annoying questions about why you didn't live up to that.
I'm that kind of fan. I read the Declaration of Independence and I've read the Constitution of the United States, and they are some liner notes, dude. As I said yesterday I made my pilgrimage to Independence Hall, and I love America because America is not just a country, it's an idea. You see my country, Ireland, is a great country, but it's not an idea. America is an idea, but it's an idea that brings with it some baggage, like power brings responsibility. It's an idea that brings with it equality, but equality even though it's the highest calling, is the hardest to reach. The idea that anything is possible, that's one of the reasons why I'm a fan of America. It's like hey, look there's the moon up there, lets take a walk on it, bring back a piece of it. That's the kind of America that I'm a fan of.
In 1771 your founder Mr. Franklin spent three months in Ireland and Scotland to look at the relationship they had with England to see if this could be a model for America, whether America should follow their example and remain a part of the British Empire.
Franklin was deeply, deeply distressed by what he saw. In Ireland he saw how England had put a stranglehold on Irish trade, how absentee English landlords exploited Irish tenant farmers and how those farmers in Franklin's words "lived in retched hovels of mud and straw, were clothed in rags and subsisted chiefly on potatoes." Not exactly the American dream...
So instead of Ireland becoming a model for America, America became a model for Ireland in our own struggle for independence.
When the potatoes ran out, millions of Irish men, women and children packed their bags got on a boat and showed up right here. And we're still doing it. We're not even starving anymore, loads of potatoes. In fact if there's any Irish out there, I've breaking news from Dublin, the potato famine is over you can come home now. But why are we still showing up? Because we love the idea of America.
