Quote #4
[…] remember that time and habit are at least as necessary to fix the true character of governments as of other human institutions […] and remember, especially, that for the efficient management of your common interests, in a country so extensive as ours, a government of as much vigor as is consistent with the perfect security of liberty is indispensable. (19.3)
Basically, Washington is reminding people that patience is a virtue. If they're not 100 percent happy with this brand-new experimental government system, the first of its kind, maybe they should give it a chance before trying to dismantle it.
Quote #5
The spirit of encroachment tends to consolidate the powers of all the departments in one, and thus to create, whatever the form of government, a real despotism. A just estimate of that love of power, and proneness to abuse it, which predominates in the human heart, is sufficient to satisfy us of the truth of this position. The necessity of reciprocal checks in the exercise of political power […] has been evinced by experiments ancient and modern. (26.2-4)
Remember, friends: absolute power corrupts absolutely. That's why it's so necessary to put checks and balances in the government, to fight against the rise of tyranny. Good thing principled men like Washington were around to put those checks and balances in place.
Quote #6
Observe good faith and justice towards all nations; cultivate peace and harmony with all. (31.1)
It's a little "Kumbaya," but since Washington died about 160 years before hippies were even a thing, we'll assume that's not the image he was going for (unless he was just really ahead of his time). Washington's plea for America to avoid foreign entanglements isn't all about politics—there are principles behind it, too. Mainly that the United States should just be good toward everyone as a general practice.
