"It would be naive to think that peace and justice can be achieved easily. No set of rules or study of history will automatically resolve the problems.... However, with faith and perseverance,... complex problems in the past have been resolved in our search for justice and peace. They can be resolved in the future, provided, of course, that we can think of five new ways to measure the height of a tall building by using a barometer."
"That night ended the day when history was written in Abilene. August 14, 1865 was the date. That was the end of the first drive on the Chisolm Trail. It was just the first of thousands of such drives bringing beef to the world."
"If man is reduced to being nothing but a character in history, he has no other choice but to subside into the sound and fury of a completely irrational history or to endow history with the form of human reason."
"... every event has had its cause, and nothing, not the least wind that blows, is accident or causeless. To understand what happens now one must find the cause, which may be very long ago in its beginning, but is surely there, and therefore a knowledge of history as detailed as possible is essential if we are to comprehend the past and be prepared for the future."
"All true histories contain instruction; though, in some, the treasure may be hard to find, and when found, so trivial in quantity that the dry, shrivelled kernel scarcely compensates for the trouble of cracking the nut."
"Neither the historian nor the cartographer can ever reproduce the reality they are trying to communicate to the reader of books or maps; they can but give a plan, a series of indications, of this reality. There are contrasting schemes for choosing from enormous numbers of geographic details. You may have a map in which every feature that can be named, every hill, brook, crossroads, is crowded in; or you may have a map in which many details are omitted in the effort to show the reader the lay of the land, the shape of the mountain systems, the relations of drainage, relief, communications, and so on. Both kinds are useful, depending on the needs of the user."
"History in the making is a very uncertain thing. It might be better to wait till the South American republic has got through with its twenty-fifth revolution before reading much about it. When it is over, some one whose business it is, will be sure to give you in a digested form all that it concerns you to know, and save you trouble, confusion, and time. If you will follow this plan, you will be surprised to find how new and fresh your interest in what you read will become."
