If a grasshopper tries to fight a lawnmower, one may admire his courage but not his judgement.
Robert A. Heinlein
If a grasshopper attempts to challenge a lawnmower, one can commend his boldness but not his wisdom.

You can sway a thousand men by appealing to their prejudices quicker than you can convince one man by logic.
Robert A. Heinlein
You can more readily move a multitude of people by appealing to their preconceived notions than you can persuade one individual through reason.

[T]here seems to have been an actual decline in rational thinking. The United States had become a place where entertainers and professional athletes were mistaken for people of importance. They were idolized and treated as leaders; their opinions were sought on everything and they took themselves just as seriously-after all, if an athlete is paid a million or more a year, he knows he is important ... so his opinions of foreign affairs and domestic policies must be important, too, even though he proves himself to be ignorant and subliterate every time he opens his mouth.

I am free, no matter what rules surround me. If I find them tolerable, I tolerate them; if I find them too obnoxious, I break them. I am free because I know that I alone am morally responsible for everything I do.

Women and cats will do as they please, and men and dogs should relax and get used to the idea.
Robert A. Heinlein
People of all genders should accept that everyone has the right to live freely and independently.
8.
Happiness lies in being privileged to work hard for long hours in doing whatever you think is worth doing. One man may find happiness in supporting a wife and children. Another may find it in robbing banks. Still another may labor mightily for years in pursuing pure research with no discernible result. Note the individual and subjective nature of each case. No two are alike and there is no reason to expect them to be. Each man or woman must find for himself or herself that occupation in which hard work and long hours make him or her happy.

Don't ever become a pessimist... a pessimist is correct oftener than an optimist, but an optimist has more fun, and neither can stop the march of events.

Political tags - such as royalist, communist, democrat, populist, fascist, liberal, conservative, and so forth - are never basic criteria. The human race divides politically into those who want people to be controlled and those who have no such desire.

It is a truism that almost any sect, cult, or religion will legislate its creed into law if it acquires the political power to do so.

Anyone who clings to the historically untrue-and thoroughly immoral-doctrine that, 'violence never settles anything' I would advise to conjure the ghosts of Napoleon Bonaparte and the Duke of Wellington and let them debate it. The ghost of Hitler could referee, and the jury might well be the Dodo, the Great Auk and the Passenger Pigeon. Violence, naked force, has settled more issues in history than has any other factor, and the contrary opinion is wishful thinking at its worst. Breeds that forget this basic truth have always paid for it with their lives and freedom.

In the absence of clearly-defined goals, we become strangely loyal to performing daily trivia until ultimately we become enslaved by it.

One of the sanest, surest, and most generous joys of life comes from being happy over the good fortune of others.

I also think there are prices too high to pay to save the United States. Conscription is one of them. Conscription is slavery, and I don't think that any people or nation has a right to save itself at the price of slavery for anyone, no matter what name it is called. We have had the draft for twenty years now; I think this is shameful. If a country can't save itself through the volunteer service of its own free people, then I say: Let the damned thing go down the drain!
Robert A. Heinlein

Secrecy is the keystone to all tyranny. Not force, but secrecy and censorship. When any government or church for that matter, undertakes to say to its subjects, "This you may not read, this you must not know," the end result is tyranny and oppression, no matter how holy the motives. Mighty little force is needed to control a man who has been hoodwinked in this fashion; contrariwise, no amount of force can control a free man, whose mind is free. No, not the rack nor the atomic bomb, not anything. You can't conquer a free man; the most you can do is kill him.
Robert A. Heinlein
28.
A fool cannot be protected from his folly. If you attempt to do so, you will not only arouse his animosity but also you will be attempting to deprive him of whatever benefit he is capable of deriving from experience. Never attempt to teach a pig to sing; it wastes your time and annoys the pig.
Robert A. Heinlein
29.
It is a truism that almost any sect, cult, or religion will legislate its creeds into law if it acquires the political power to do so, and will follow it by suppressing opposition, subverting all education to seize early the minds of the young, and by killing, locking up, or driving underground all heretics.

Ability is a wonderful thing, but its value is greatly enhanced by dependability. Ability implies repeatability and accountability.

A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly.

Mighty little force is needed to control a man whose mind has been hoodwinked; contrariwise, no amount of force can control a free man, a man whose mind is free. No, not the rack, not fission bombs, not anything - you can't conquer a free man; the most you can do is kill him.

What is supposed to happen in a democracy is that each sovereign citizen will always vote in the public interest for the safety and welfare of all. But what does happen is that he votes his own self-interest as he sees it... which for the majority translates as 'Bread and Circuses'.
