“The government of the Union, then, … is, emphatically, and truly, a government of the people. In form and in substance it emanates from them. Its powers are granted by them, and are to be exercised directly on them, and for their benefit.”

Quote, First State of the Union Address (1865)
Context: Our Government springs from and was made for the people — not the people for the Government. To them it owes allegiance; from them it must derive its courage, strength, and wisdom. But while the Government is thus bound to defer to the people, from whom it derives its existence, it should, from the very consideration of its origin, be strong in its power of resistance to the establishment of inequalities. Monopolies, perpetuities, and class legislation are contrary to the genius of free government, and ought not to be allowed. Here there is no room for favored classes or monopolies; the principle of our Government is that of equal laws and freedom of industry. Wherever monopoly attains a foothold, it is sure to be a source of danger, discord, and trouble. We shall but fulfill our duties as legislators by according "equal and exact justice to all men," special privileges to none.

Context: This government is acknowledged by all to be one of enumerated powers. The principle, that it can exercise only the powers granted to it, would seem too apparent to have required to be enforced by all those arguments which it enlightened friends, while it was depending before the people, found it necessary to urge. That principle is now universally admitted. But the question respecting the extent of the powers actually granted, is perpetually arising, and will probably continue to arise, as long as our system shall exist.

McCulloch v. Maryland (1819)
Context: The convention which framed the Constitution was indeed elected by the State legislatures. But the instrument, when it came from their hands, was a mere proposal, without obligation or pretensions to it. It was reported to the then existing Congress of the United States with a request that it might "be submitted to a convention of delegates, chosen in each State by the people thereof, under the recommendation of its legislature, for their assent and ratification." This mode of proceeding was adopted, and by the convention, by Congress, and by the State legislatures, the instrument was submitted to the people. They acted upon it in the only manner in which they can act safely, effectively and wisely, on such a subject — by assembling in convention. It is true, they assembled in their several States — and where else should they have assembled? No political dreamer was ever wild enough to think of breaking down the lines which separate the States, and of compounding the American people into one common mass. Of consequence, when they act, they act in their States. But the measures they adopt do not, on that account, cease to be the measures of the people themselves, or become the measures of the State governments. From these conventions the Constitution derives its whole authority. The government proceeds directly from the people; is "ordained and established" in the name of the people, and is declared to be ordained, "in order to form a more perfect union, establish justice, insure domestic tranquillity, and secure the blessings of liberty to themselves and to their posterity." The assent of the States in their sovereign capacity is implied in calling a convention, and thus submitting that instrument to the people. But the people were at perfect liberty to accept or reject it, and their act was final. It required not the affirmance, and could not be negatived, by the State Governments. The Constitution, when thus adopted, was of complete obligation, and bound the State sovereignties.

This quote is incorrectly quoted from Lincoln's Address to Congress on July 4, 1861 http://millercenter.org/president/speeches/detail/3508, in which Lincoln outlined the events that had led to the American Civil War and his views on the nature of the rebellion by the southern slave states. To suppress the rebellion Lincoln said that Congress must "give the legal means for making this contest a short and a decisive one; that you place at the control of the Government for the work at least 400,000 men and $400,000,000." And Lincoln remarked further: "A right result at this time will be worth more to the world than ten times the men and ten times the money. The evidence reaching us from the country leaves no doubt that the material for the work is abundant, and that it needs only the hand of legislation to give it legal sanction and the hand of the Executive to give it practical shape and efficiency. One of the greatest perplexities of the Government is to avoid receiving troops faster than it can provide for them. In a word, the people will save their Government if the Government itself will do its part only indifferently well".

1840s
Context: Any people anywhere being inclined and having the power have the right to rise up and shake off the existing government, and form a new one that suits them better. This is a most valuable, a most sacred right — a right which we hope and believe is to liberate the world. Nor is this right confined to cases in which the whole people of an existing government may choose to exercise it. Any portion of such people that can may revolutionize and make their own of so much of the territory as they inhabit.
