“The current understanding that all organisms share a common evolutionary origin is based in part on this observed universality of chemical intermediates and transformations, often termed "biochemical unity."”

“The huge human brain, approximately 1,350 cubic centimeters, is the most complex organic structure in the known world. Understanding the human mind/brain mechanisms in evolutionary perspective is the goal of the new scientific discipline called evolutionary psychology. Evolutionary psychology focuses on four key questions: (1) Why is the mind designed the way it is—that is, what causal processes created, fashioned, or shaped the human mind into its current form? (2) How is the human mind designed—what are its mechanisms or component parts, and how are they organized? (3) What are the functions of the component parts and their organized structure—that is, what is the mind designed to do? (4) How does input from the current environment interact with the design of the human mind to produce observable behavior?”

“All life on earth - everything from bacteria to mushrooms to hippos - shares an astonishing range of detailed biochemical similarities, including the structure of heredity in DNA and RNA, and the universal use of ATP as an energy-storing compound. Two possible scenarios, with markedly different implications for the nature of life, might explain these regularities: either all earthly life shares these features because no other chemistry can work, or these similarities only record the common descent of all organisms on earth from a single origin that happened to feature this chemistry as one possibility among many.”

“Organization always hinges on the creation of shared meanings and shared understandings, because there have to be common reference points if people are to shape an align their activities in an organized way.”

“... I have no reason to doubt that the universe is the billions of years old that physicists say it is. Further, I find the idea of common descent (that all organisms share a common ancestor) fairly convincing, and have no reason to doubt it. ... I think that evolutionary biologists have contributed enormously to our understanding of the world. Although Darwin's mechanism - natural selection working on variation - might explain many things, however, I do not believe it explains molecular life.”

“Pure rationality and limited rationality share a common perspective, seeing decisions as based on evaluation of alternatives in terms of their consequences for preferences. This logic of consequences can be contrasted with a logic of appropriateness by which actions are matched to situations by means of rules organized into identities.”

“If I try to hold on the currently predominant view and derive the unity of my self, … I find myself with an impenetrable thicket of questions. … Why is it precisely at this intermediate level in the hierarchy of successively superimposed unities (cell, organ, human body, state)—why, I ask, it is precisely at the level of my body that unitary self-consciousness comes into the picture, whereas the cell and the organ do not as yet possess it and the state possesses it no longer?”

“Organization is not only directly linked to unity, but a natural development of that unity. Accordingly, the leaders' pursuit of that unity is also an attempt to organize the people, requiring witness to the fact that the struggle for liberation is a common task.”
