When a sixth of the population of a nation which has undertaken to be the refuge of liberty are slaves, and a whole country [Mexico] is unjustly overrun and conquered by a foreign army, and subjected to military law, I think that it is not too soon for honest men to rebel and revolutionize. What makes this duty the more urgent is the fact that the country so overrun is not our own, but ours is the invading army.

Men are in the main alike, but they were made several in order that they might be various. If a low use is to be served, one man will do nearly quite as well as another; if a high one, individual excellence is to be regarded.

The golden mean in ethics, as in physics, is the centre of the system and that about which all revolve, and though to a distant and plodding planet it be an uttermost extreme, yet one day, when that planet's year is completed, it will be found to be central.

If we were always, indeed, getting our living, and regulating our lives according to the last and best mode we had learned, we should never be troubled with ennui.

The heroic books, even if printed in the character of our mother tongue, will always be in a language dead to degenerate times; and we must laboriously seek the meaning of each word and line, conjecturing a larger sense than common use permits out of what wisdom and valor and generosity we have.

They seem as solitary, and the letter in which they are printed as rare and curious, as ever.

If I deny the authority of the State when it presents my tax bill, it will soon take and waste all my property, and so harass me and my children without end. This is hard, this makes it impossible for a man to live honestly, and at the same time comfortably, in outward respects.

A person who chooses to die or to risk death demonstrates that there are values, principles, maxims, that are more valuable to him than is life itself. In short, he places his immortal self above his mortal self. Nothing goes by luck in composition. It allows of no tricks. The best you can write will be the best you are.
