Liberty, according to my metaphysics is a self-determining power in an intellectual agent. It implies thought and choice and power. - John Adams
 

 Our Constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other. - John Adams

I must study politics and war that my sons may have liberty to study mathematics and philosophy. - John Adams

In politics the middle way is none at all. - John Adams

When people talk of the freedom of writing, speaking or thinking I cannot choose but laugh. No such thing ever existed. No such thing now exists; but I hope it will exist. But it must be hundreds of years after you and I shall write and speak no more. 

 -John Adams

 Remember, democracy never lasts long. It soon wastes, exhausts, and murders itself. There never was a democracy yet that did not commit suicide.  -John Adams

 Power always thinks... that it is doing God's service when it is violating all his laws. 

- John Adams

 Posterity! You will never know how much it cost the present generation to preserve your freedom! I hope you will make a good use of it. 

-John Adams
