“In politics the middle way is none at all.”

“When John Quincy Adams in the Netherlands was placed with elementary students and belittled because he did not speak Dutch, either the author or John Adams accuses school authorities of "littleness of soul".”

“When writing the constitution for the Commonwealth of Massachusetts, John Adams wrote:I must judge for myself, but how can I judge, how can any man judge, unless his mind has been opened and enlarged by reading.”

“Our obligations to our country never cease but with our lives. - John Adams”

“As we look over the list of the early leaders of the republic, Washington, John Adams, Hamilton, and others, we discern that they were all men who insisted upon being themselves and who refused to truckle to the people. With each succeeding generation, the growing demand of the people that its elective officials shall not lead but merely register the popular will has steadily undermined the independence of those who derive their power from popular election. The persistent refusal of the Adamses to sacrifice the integrity of their own intellectual and moral standards and values for the sake of winning public office or popular favor is another of the measuring rods by which we may measure the divergence of American life from its starting point.”

“The author perceives nuances of Abigail Adams' character in the occasional errors she makes in readily quoting John Milton. Rather than giving the observer a reason to quibble, they are evidence that she had absorbed Milton's works enough to feel comfortable quoting them from memory.”

“The author perceptively outlines what might be an underrated aspect of his subject and of many others whose public achievements are of note – a "gift for friendship". McCullough says Adams, despite his towering intellect and curmudgeonly demeanor, had a soft heart for other people and a genuine interest in their particulars.”

“The more Adams thought about the future of his country, the more convinced he became that it rested on education. Before any great things are accomplished, he wrote to a correspondent, a memorable change must be made in the system of education and knowledge must become so general as to raise the lower ranks of society nearer to the higher. The education of a nation instead of being confined to a few schools and universities for the instruction of the few, must become the national care and expense for the formation of the many.”

“Negro Slavery is an evil of Colossal magnitude and I am utterly averse to the admission of Slavery into the Missouri Territories.”

“The true source of our sufferings has been our timidity.”

“It is more important that innocence be protected than it is that guilt be punished, for guilt and crimes are so frequent in this world that they cannot all be punished.But if innocence itself is brought to the bar and condemned, perhaps to die, then the citizen will say, 'whether I do good or whether I do evil is immaterial, for innocence itself is no protection,' and if such an idea as that were to take hold in the mind of the citizen that would be the end of security whatsoever.”
