The experiences of the years…have brought the country, particularly its young people, to a mood of depression, disillusion, and withdrawal from the effort to affect the world.

In the last two decades we have witnessed the emergence of the "system" as a key concept in scientific research. Systems, of course, have been studied for centuries, but something new has been added… The tendency to study systems as an entity rather than as a conglomeration of parts is consistent with the tendency in contemporary science no longer to isolate phenomena in narrowly confined

contexts, but rather to open interactions for examination and to examine larger and larger slices of nature. Under the banner of systems research (and its many synonyms) we have also witnessed a convergence of many more specialized contemporary scientific developments… These research pursuits and many others are being interwoven into a cooperative research effort involving an ever-widening

spectrum of scientific and engineering disciplines. We are participating in what is probably the most comprehensive effort to attain a synthesis of scientific knowledge yet made.

The effort to get rid of what we do not want is reactive, retrospectively oriented problem solving. The effort to obtain what we want is proactive, prospectively oriented problem solving.

I have often thought that if photography were difficult in the true sense of the term — meaning that the creation of a simple photograph would entail as much time and effort as the production of a good watercolor or etching — there would be a vast improvement in total output. The sheer ease with which we can produce a superficial image often leads to creative disaster.

This is the most magnificent movement of all! There is a dignity, a majesty, a sublimity, in this last effort of the patriots that I greatly admire. The people should never rise without doing something to be remembered — something notable and striking. This destruction of the tea is so bold, so daring, so firm, intrepid and inflexible, and it must have so important consequences, and so lasting,

that I can't but consider it as an epocha in history!

Nothing could be worse than the fear that one had given up too soon, and left one unexpended effort that might have saved the world.

The Settlement … is an experimental effort to aid in the solution of the social and industrial problems which are engendered by the modern conditions of life in a great city. It insists that these problems are not confined to any one portion of the city. It is an attempt to relieve, at the same time, the overaccumulation at one end of society and the destitution at the other …

There is a city to be built, the plan of which we carry in our heads, in our hearts. Countless generations have already toiled at the building of it. The effort to aid in completing it, with us, takes the place of prayer. In this sense we say, "Laborare est orare."

The books to be read should not be limited to those written in English…. Instead it should be devoted to the great works of history, biography, philosophy, theology, natural science, social science, and mathematics, as well as the… tradition of Western literature -- in English translation… Its aim should not be a survey of Western civilization, but an effort to understand the basic ideas and

issues in Western thought.

I think it's a disgrace for the international community that we have allowed so many conflicts to become frozen, and we are not making a serious effort to solve them.
