[Chap. XL] MY NEW IDEAS

rational and sympathetic training and a social system which 

 gave to all absolute equality of opportunity, might not 

 become useful, contented, and happy members of society, I 

 became much more tolerant. I learnt also to distrust all first

 here give a brief account of the more important of them, 

 some of which have, I think, been almost entirely overlooked. 



1. The first and perhaps the most important of these is 

 my independent discovery of the theory of natural selection 

 in 1858, in my paper on "The Tendency of Varieties to 

 depart indefinitely from the Original Type." This is reprinted 

 in my " Natural Selection and Tropical Nature ; " and it has

 Chapter XXII. of this work. 



2. In 1864 I published an article on "The Development 

 of Human Races under the Law of Natural Selection," the 

 most original and important part of which was that in which 

 I showed that so soon as man's intellect and physical struc- 

 ture led him to use fire, to make tools, to grow food, to 

 domesticate animals, to use clothing, and build houses, the
