“The most valuable of all talents is that of never using two words when one will do.”

“A strong body makes the mind strong. As to the species of exercises, I advise the gun. While this gives moderate exercise to the body, it gives boldness, enterprise and independence to the mind. Games played with the ball and others of that nature are too violent for the body and stamp no character on the mind. Let your gun therefore be your constant companion of your walks.”

“I hope they pardoned them. The spirit of resistance to government is so valuable on certain occasions, that i wish it to be always kept alive....I like a little rebellion now and then. It is like a storm in the atmosphere.”

“All eyes are opened, or opening, to the rights of man. The general spread of the light of science has already laid open to every view the palpable truth that the mass of mankind has not been born with saddles on their backs, nor a favored few booted and spurred, ready to ride them legitimately, by the grace of God. These are grounds of hope for others. For ourselves, let the annual return of this day forever refresh our recollection of these rights, and an undiminished devotion to them.”

“the measure of society is how it treats the weakest members”

“I haven't failed. I've just found 10,000 ways that don't work.”

“Without books, I would certainly die.”

“I believe that banking institutions are more dangerous to our liberties than standing armies.” 

“I like the dreams of the future better than the history of the past.”

“The constitution of most of the states (and of the United States) assert that all power is inherent in the people; that they may exercise it by themselves; that it is their right and duty to be at all times armed and that they are entitled to freedom of person, freedom of religion, freedom of property, and freedom of the press.”

“Some men look at constitutions with sanctimonious reverence, and deem them like the ark of the covenant, too sacred to be touched. They ascribe to the men of the preceding age a wisdom more than human, and suppose what they did to be beyond amendment. I knew that age well; I belonged to it, and labored with it. It deserved well of its country. It was very like the present, but without the experience of the present; and forty years of experience in government is worth a century of book-reading; and this they would say themselves, were they to rise from the dead. I am certainly not an advocate for frequent and untried changes in laws and constitutions. I think moderate imperfections had better be borne with; because, when once known, we accommodate ourselves to them, and find practical means of correcting their ill effects. But I know also, that laws and institutions must go hand in hand with the progress of the human mind. As that becomes more developed, more enlightened, as new discoveries are made, new truths disclosed, and manners and opinions change with the change of circumstances, institutions must advance also, and keep pace with the times. We might as well require a man to wear still the coat which fitted him when a boy, as civilized society to remain ever under the regimen of their barbarous ancestors.” 

“Freedom, the first-born of science.”

“I felt enough of the effect of withdrawing from the world then, to see that it led to an antisocial and misanthropic state of mind, which severely punished him who gives in to it. And it will be a lesson I never shall forget as to myself.”

“A great deal of love given to a few is better than a little to many.”

“Equal and exact justice to all men, of whatever state or persuasion.”
