“We can assume that in a relatively short time — perhaps within 100 million years — the one celled organism evolved into a colony of cells. With the further passage of time, groups of cells within those colonies assumed specialized functions of food-gathering, digestion, the structural features of an outer skin, and so on; thus began the stage of evolution leading to the complex, many-celled creatures which dominate life today.
The fossil record contains no trace of these preliminary stages in the development of many-celled organisms. The first clues to the existence of relatively advanced forms of life consist of a few barely discernible tracks, presumably made in the primeval slime by soft, wriggling wormlike animals. These are found in rocks about one billion years old. These meager remains are the earliest traces of many-celled animal life on the planet.”

“Nonsense wakes up the brain cells. And it helps develop a sense of humor, which is awfully important in this day and age.”

Dr. Seuss (1904–1991) American children's writer and illustrator, co-founder of Beginner Books

As quoted in "Author Isn't Just a Cat in the Hat" by Miles Corwin in The Los Angeles Times (27 November 1983); also in Dr. Seuss: American Icon (2004) by Philip Nel, p. 38
Context: Nonsense wakes up the brain cells. And it helps develop a sense of humor, which is awfully important in this day and age. Humor has a tremendous place in this sordid world. It's more than just a matter of laughing. If you can see things out of whack, then you can see how things can be in whack.

“The fundamental division of forms of life on Earth is not that between plants and animals, as is commonly assumed, but between prokaryotes—organisms composed of cells with no nucleus, that is, bacteria—and eukaryotes—all other life forms.”

“[Another significant aspect of the concept of growth is the distinction that Mesarovic and Pestel draw between "undifferentiated" and "organic" growth. The former type of growth, according to these authors, consists of mere replication of cells by cellular division, usually expotentially, with an increase in quantity alone. The latter type of growth] involves a process of differentiation, which means that various groups of cells begin to differ in structure and function… During and after differentiation the number of cells can still increase, and the organs grow in size, but while some organs grow, others might celine.”

“To rationalize their lies, people — and the governments, churches, or terrorist cells they compose — are apt to regard their private interests and desires as just.”

Wendy Kaminer (1949) American lawyer

"Lies and consequences." in The American Prospect (19 May 2002) http://prospect.org/cs/articles?article=lies_and_consequences&gId=6282
Context: To rationalize their lies, people — and the governments, churches, or terrorist cells they compose — are apt to regard their private interests and desires as just. Clinton may have lied to preserve his power while telling himself that he was lying to protect “the people” who benefited from his presidency. Liars — especially liars in power — often conflate their interest with the public interest. (What’s good for General Motors is good for the United States.) Or they consider their lies sanctified by the essential goodness they presume to embody, like terrorists who believe that murder is sanctified by the godliness of their aspirations. Sanctimony probably engenders at least as much lying as cynicism. We can’t condemn lying categorically, but we should categorically suspect it.

“Cajal revealed the precision of the interconnections between populations of individual nerve cells. Mountcastle, Hubel, and Wiesel revealed the functional significance of those patterns of interconnections. They showed that the connections filter and transform sensory information on the way to and within the cortex, and that the cortex is organized into functional compartments, or modules.”
