“Anyone who can't learn from other people's mistakes simply can't learn, and that;s all there is to it. There is value in the wrong way of doing things. The knowledge gained from errors contributes to our knowledge base.”

“And, you know, what we need to do—[applause]what we need to do in this PC world is forget about unanimity of speech and unanimity of thought, and we need to concentrate on being respectful to those people with whom we disagree.”

“Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive.”

“This power became addicting to many elected officials who, instead of going to Washington, DC, for a brief time to represent their constituency, wanted to hold their positions for extended periods of time — even for life. This growing power and the progressive intrusion of government into the lives of the people was so insidious that it went largely undetected.”

“Everyone in the world worth being nice to. Because God never creates inferior human beings, each person deserves respect and dignity.”

“Anyone who writes a law that cannot be easily understood by an average citizen is not worthy of leadership.

“We were very poor. But between the covers of books I could go anywhere, I could be anybody, I could do anything. I began to read about people of great accomplishment.

You decide how much energy you want to put behind that decision.”

“I practiced in Australia for one year as a neurosurgeon, and my malpractice premiums were only $200 a year at that time. Compare this with the $300,000 malpractice insurance fee assessed on a litigation-free neurosurgeon in Philadelphia today.”

“Our country, as well as the rest of the world, faces an enormous threat from ISIS and other radical Islamic terrorist organizations that aspire to achieve world domination. These were the same aspirations held by the followers of Adolf Hitler in the 1930s. Our government must recognize the importance of directly and vigorously confronting these forces of evil. We must not make the mistake of avoiding necessary conflict; we did not get involved in World War I or World War II until we felt that American interests were directly threatened, and this proved to be the wrong choice, though we eventually were victorious. If a vicious enemy that is willing to decapitate people, burn people alive, and even crucify children is allowed to grow with only minor to moderate resistance, it will only become a more formidable adversary in the future. If during this period of tepid responses to terrorist expansion the radical Islamists manage to acquire nuclear weapons, providing for the common defense will take on an entirely new different meaning. The longer we wait to eliminate the threat, the more difficult that task will become and the more dangerous the world will be for our children and grandchildren. We must use all necessary resources to protect the lives of our people. Given the existence of enemies who have a stated goal of destroying our nation and our way of life, one way to provide for the common defense is to hide, which in our case would not be possible. A better option is to try to eliminate the threat, and the earlier the threat can be eliminated, the fewer lives will be lost in the conflict.”

“Wisdom is essentially the same thing as common sense, the slight difference is that common sense provides the ability to react appropriately, while wisdom is frequently more proactive and additionally encourages the shaping of the environment.”

“If you wouldn’t join in a mugging you saw taking place on a street, if you wouldn’t physically attack or verbally abuse and cruelly insult an acquaintance in your school, why would you ever ridicule or hurl vicious and hurtful words at a person online?”

“The bottom line was that we have only ourselves to blame. We create our own destiny by the way we do things. We have to take advantage of opportunities”
