Bertrand Russell Quotes(バートランド・ラッセルの名言・警句)

 


To be able to concentrate on the same matter for a considerable time is essential to difficult achievement, and even to the understanding of any complicated or abstruse subject. A profound spontaneous interest brings this about naturally, so far as the object of interest is concerned. Most people can concentrate on a mechanical puzzle for a long time ; but this is not in itself very useful. To be really valuable, the concentration must also be within the control of the will.
