Quote #4
In contemplating the causes which may disturb our Union, it occurs as matter of serious concern that any ground should have been furnished for characterizing parties by geographical discriminations, Northern and Southern, Atlantic and Western; whence designing men may endeavor to excite a belief that there is a real difference of local interests and views. (15.1)
In some pretty spot-on foreshadowing, Washington fears that some people will exploit regional differences to turn those regions against one another. Again, he tries to emphasize patriotism to the whole nation over a local area. It was a good effort, George, but your buddy Abraham (whom you never met) is going to have a lot of regional "difference" on his plate in about 60 years.
Quote #5
In offering to you, my countrymen, these counsels of an old and affectionate friend, I dare not hope they will make the strong and lasting impression I could wish; that they will control the usual current of the passions, or prevent our nation from running the course which has hitherto marked the destiny of nations. (42.1)
Although it's a little depressing that Washington seems to be a bit pessimistic about the future, the idea that he's trying to prevent America's doom is another form of patriotism. He found himself in a position of real power, and instead of taking advantage of it for his own gain, he did what he could to set up the country for success. Even if his efforts only worked a little bit, the intent is just about as patriotic as you can get. That's love for your country right there.
