The Way to be a Thinker 



is to get in touch with thinkers. All the world's prizes are captured by 

 those who have seasoned their energy with the spice of originality and 

 originality means the habit of clear and fresh thinking. Originality can 

 be developed and is developed by contact with original minds. Even 

 the best of us have a tendency to fall into mental ruts, to go plodding 

 on, year after year, in the same track, to do things without knowing 

 precisely why. The way to keep alive, the way to be original, the way 

 to be a success, is to talk with brainy people and to read books that 

 make you think. That 's the reason the 



NEW SCIENCE LIBRARY 



is a cure for mental paralysis. It contains the best work of Darwin, 

 Huxley, Spencer, Tyndall, and other great leaders of modern thought. 

 It will tell you what the famous Darwinian theory is; how the planets 

 are weighed and their motions charted; what radium is; what ideas 

 Herbert Spencer brought into the world; how liquid air is made and 

 used and ten thousand other interesting things you have always 

 wanted to know. It is a work to be read and enjoyed, for it is written in 

 a clear and interesting style not abstruse or technical. H The work con- 

 sists of sixteen superb volumes, handsomely printed and bound.
