“We want one class of persons to have a liberal education, and we want another class of persons, a very much larger class of necessity in every society, to forgo the privilege of a liberal education and fit themselves to perform specific difficult manual tasks.”

“We have not given science too big a place in our education, but we have made a perilous mistake in giving it too great a preponderance in method in every other branch of study.”

“[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.”

“We forget that there is much more patriotism in having the audacity to differ from the majority than in running before the crowd; we forget that in the resistance of the minority some of the biggest things in our own history have been accomplished, and the man who looks on the Stars and Stripes and doesn't hold a right to say nay to his neighbor, even if the neighbor is of the larger party, has forgotten the history of his country.”

“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 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...”

“We should not only use all the brains we have but all that we can borrow.”

“A nation which does not remember what it was yesterday, does not know what it is today, nor what it is trying to do. We are trying to do a futile thing if we do not know where we came from or what we have been about.”
