We do not inhabit a perfected world where natural selection ruthlessly scrutinizes all organic structures and then molds them for optimal utility. Organisms inherit a body form and a style of embryonic development; these impose constraints upon future change and adaptation. In many cases, evolutionary pathways reflect inherited patterns more than current environmental demands. These inheritances constrain, but they also provide opportunity. A potentially minor genetic change [...] entails a host of complex, nonadaptive consequences. [...] What "play” would evolution have if each structure were built for a restricted purpose and could be used for nothing else? How could humans learn to write if our brain had not evolved for hunting, social cohesion, or whatever, and could not transcend the adaptive boundaries of its original purpose? (Stephen Jay Gould)

We have entered a time of global transition marked by uniquely contradictory trends. Regional and continental associations of States are evolving ways to deepen cooperation and ease some of the contentious characteristics of sovereign and nationalistic rivalries. National boundaries are blurred by advanced communications and global commerce, and by the decisions of States to yield some sovereign prerogatives to larger, common political associations. At the same time, however, fierce new assertions of nationalism and sovereignty spring up, and the cohesion of States is threatened by brutal ethnic, religious, social, cultural or linguistic strife. Social peace is challenged on the one hand by new assertions of discrimination and exclusion and, on the other, by acts of terrorism seeking to undermine evolution and change through democratic means.

Sitting Bull, most renowned Sioux of modern history, is dead. He was not a Chief, but without Kingly lineage he arose from a lowly position to the greatest Medicine Man of his time, by virtue of his shrewdness and daring. He was an Indian with a white man's spirit of hatred and revenge for those who had wronged him and his. In his day he saw his son and his tribe gradually driven from their possessions: forced to give up their old hunting grounds and espouse the hard working and uncongenial avocations of the whites. And these, his conquerors, were marked in their dealings with his people by selfishness, falsehood and treachery. What wonder that his wild nature, untamed by years of subjection, should still revolt? What wonder that a fiery rage still burned within his breast and that he should seek every opportunity of obtaining vengeance upon his natural enemies.

[T]he psychic and physical characteristics of human beings, and the differences between individuals, are the consequence of an interaction between the genes that are present in the fertilized egg and the sequence of environmental circumstances that the developing organism experiences during its entire life history. With a few exceptions, like cystic fibrosis where possession of the defective genotype leads ineluctably to the disease, or language acquisition where the language spoken depends only on experience and not at all on genotype, human characteristics are all subject to this interaction of forces. There are, moreover, random events in cell growth and differentiation that are neither genetic nor environmental in the usual sense, and which play an extremely important part in development, especially in behavioral traits.

Richard Lewontin

The need for a fundamentally different approach to the study of physical processes at the molecular level motivated the development of relevant statistical methods, which turned out to be applicable not only to the study of molecular processes (statistical mechanics), but to a host of other areas such as the actuarial profession, design of large telephone exchanges, and the like. In statistical methods, specific manifestations of microscopic entities (molecules, individual telephone sites, etc.) are replaced with their statistical averages, which are connected with appropriate macroscopic variables. The role played in Newtonian mechanics by the calculus, which involves no uncertainty, is replaced in statistical mechanics by probability theory, a theory whose very purpose is to capture uncertainty of a certain type.

I gave up on this stuff. I gave up on my species and ... I gave up on my countrymen. Because I think we squandered great gifts. I think humans were given great great gifts: walking upright, binocular vision, opposable thumb, large brain ... We grew. We had great gifts, and we gave it all up for both money and God ... We gave it all up to superstition, primitive superstition, primitive shit ... Invisible man in the sky, looking down, keeping track of what we do, make sure we don't do the wrong thing, if we do, he puts us in hell, where we burn forever. That kind of shit is very limiting for this brain we have. So we keep ourselves limited. And then we want a toy and a gizmo and gold and we want shiny things, and we want something to plug in that will make big big big things for us... And all that shit is nothing! It's nothing.
