The right method in any particular case must be largely determined by the nature of the problem. - Arnold Toynbee

You must pursue facts for their own sake, but penetrated with a vivid sense of the problems of your own time. This is not a principle of perversion, but a principle of selection. You must have some principle of selection, and you could not have a better one than to pay special attention to the history of the social problems which are agitating the world now, for you may be sure that they are problems not of temporary but of lasting importance.

We must expect for a long time yet to see capitalists still striving to obtain the highest possible profits. But observe, that the passion for wealth is certainly in some senses new. It grew up very rapidly at the beginning of the present century; it was not so strong in the last century, when men were much more content to lead a quiet easy life of leisure. The change has really influenced the relations between men; but in the future it is quite possible that the scramble for wealth may grow less intense, and a change in the opposite direction take place.
