The world has a habit of going on.

The President is at liberty, both in law and conscience, to be as big a man as he can. His capacity will set the limit; and if Congress be overborne by him, it will be no fault of the makers of the Constitution, – it will be from no lack of constitutional powers on its part, but only because the President has the nation behind him, and the Congress has not.”

“The chief instrumentality by which the law of the Constitution has been extended to cover the facts of national development has of course been judicial interpretation, – the decisions of the courts. The process of formal amendment of the Constitution was made so difficult by provisions of the Constitution itself that it has seldom been feasible to use it; and the difficulty of formal amendment has undoubtedly made the courts more liberal, not to say lax, in their interpretation than they would otherwise have been. The whole business of adaptation has been theirs, and they have undertaken it with open minds, sometimes even with boldness and a touch of audacity...”

“The old theory of the sovereignty of the States, which used so to engage our passions, has lost its vitality. The war between the States established at least this principle, that the federal government is, through its courts, the final judge of its own powers... We are impatient of state legislatures because they seem to us less representative of the thoughtful opinion of the country than Congress is. We know that our legislatures do not think alike, but we are not sure that our people do not think alike...

Freedom exists only where people take care of the government.

There is nothing that succeeds in life like boldness, provided you believe you are on the right side.

[o]f course like every other man of intelligence and education I do believe in organic evolution. It surprises me that at this late date such questions should be raised.

It is ... particularly true of constitutional government that its atmosphere is opinion .... It does not remain fixed in any unchanging form, but grows with the growth and is altered with the change of the nation's needs and purposes.

You are not here merely to making a living. You are here in order to enable the world to live more amply, with greater vision, with a finer spirit of hope and achievement.

When men take up arms to set other men free, there is something sacred and holy in the warfare.

Just what is it that America stands for? If she stands for one thing more than another it is for the sovereignty of self-governing people.

no society is renewed from the top and every society is renewed from the bottom.

I would rather fail in a cause that would ultimately succeed, than succeed in a cause that would ultimately fail.
