“In the United States both scholars and the general public have been conditioned to viewing human races as natural and separate divisions within the human species based on visible physical differences. With the vast expansion of scientific knowledge in this century, however, it has become clear that human populations are not unambiguous, clearly demarcated, biologically distinct groups. Evidence from the analysis of genetics (e.g. DNA) indicates that most physical variation, about 94%, lies within so-called racial groups. Conventional geographic "racial" groupings differ from one another only in about 6% of their genes. This means that there is greater variation within "racial" groups than between them. In neighboring populations there is much overlapping of genes and their phenotypic (physical) expressions. Throughout history whenever different groups have come into contact, they have interbred. The continued sharing of genetic materials has maintained all of humankind as a single species.”

“As this book will show, objectively defined races simply do not exist. Even Arthur Mourant realized that fact nearly fifty years ago, when he wrote: 'Rather does a study of blood groups show a heterogeneity in the proudest nation and support the view that the races of the present day are but temporary integrations in the constant process of . . . mixing that marks the history of every living species.' The temptation to classify the human species into categories which have no objective basis is an inevitable but regrettable consequence of the gene frequency system when it is taken too far. For several years the study of human genetics got firmly bogged down in the intellectually pointless (and morally dangerous) morass of constructing ever more detailed classifications of human population groups.”

“It is a bad sign when the people of a country stop identifying themselves with the country and start identifying with a group. A racial group. Or a religion. Or a language. Anything, as long as it isn't the whole population.”

“Most whites do not have a racial identity, but they would do well to understand what race means for others. They should also ponder the consequences of being the only group for whom such an identity is forbidden and who are permitted no aspirations as a group.”

“A man has as many social selves as there are distinct groups of persons about whose opinion he cares. He generally shows a different side of himself to each of these different groups.”

“The human species is an animal species without very much variation within it, and it is idle and futile to imagine that a voyage to Tibet, say, will discover an entirely different harmony with nature or eternity.”
