“With highly civilised nations continued progress depends in a subordinate degree on natural selection; for such nations do not supplant and exterminate one another as do savage tribes. Nevertheless the more intelligent members within the same community will succeed better in the long run than the inferior, and leave a more numerous progeny, and this is a form of natural selection. The more efficient causes of progress seem to consist of a good education during youth whilst the brain is impressible, and of a high standard of excellence, inculcated by the ablest and best men, embodied in the laws, customs and traditions of the nation, and enforced by public opinion. It should, however, be borne in mind, that the enforcement of public opinion depends on our appreciation of the approbation and disapprobation of others; and this appreciation is founded on our sympathy, which it can hardly be doubted was originally developed through natural selection as one of the most important elements of the social instincts.”

2015, Remarks to the People of Africa (July 2015)
Context: [... ] let girls learn so they grow up healthy and they grow up strong. And that will be good for families. And they will raise smart, healthy children, and that will be good for every one of your nations. Africa is the beautiful, strong women that these girls grow up to become. The single best indicator of whether a nation will succeed is how it treats its women. When women have health care and women have education, families are stronger, communities are more prosperous, children do better in school, nations are more prosperous. Look at the amazing African women here in this hall. If you want your country to grow and succeed, you have to empower your women. […] Let’s work together to stop sexual assault and domestic violence. Let’s make clear that we will not tolerate rape as a weapon of war -- it’s a crime. And those who commit it must be punished.  Let’s lift up the next generation of women leaders who can help fight injustice and forge peace and start new businesses and create jobs -- and some might hire some men, too. We’ll all be better off when women have equal futures.

Context: Our progress as a nation can be no swifter than our progress in education. Our requirements for world leadership, our hopes for economic growth, and the demands of citizenship itself in an era such as this all require the maximum development of every young American's capacity. The human mind is our fundamental resource.

Context: Where natural selection slackens, new forms may arise which would not survive under more rigid competition, and many ultimately hardy combinations will thus have a chance of arising.... Thus the distinction between the principal mammalian orders seems to have arisen during an orgy of variation in the early Eocene which followed the doom of the great reptiles... Since that date mammalian evolution has been a slower affair, largely a progressive improvement of the types originally laid down in the Eocene.
Another possible mode of making rapid evolutionary jumps is by hybridisation.... hybridisation (where the hybrids are fertile) usually causes an epidemic of variation in the second generation which may include new and valuable types which could not have arisen within a species by slower evolution.

Kosmos (1845 - 1847)
Context: While we maintain the unity of the human species, we at the same time repel the depressing assumption of superior and inferior races of men. There are nations more susceptible of cultivation, more highly civilized, more enobled by mental cultivation than others, but none in themselves nobler than others. All are in like degree designed for freedom; a freedom which, in the ruder conditions of society, belongs only to the individual, but which, in social states enjoying political institutions, appertains as a right to the whole body of the community.
