“The fact that the span of apprehension averages only four or five… probably results from the high rate of encoding. In a tachistoscopic experiment the subject must read the fading icon as rapidly as possible.”

“The result is that constitutional precedents are accepted only at their current valuation and have a mortality rate almost as high as their authors.”

Robert H. Jackson (1892–1954) American judge

Source: "The Task of Maintaining Our Liberties: The Role of the Judiciary" (1953), P. 962
Context: For over a century it has been the settled doctrine of the Supreme Court that the principle of stare decisis has only limited application in constitutional cases. It might be thought that if any law is to be stabilized by a court decision it logically should be the most fundamental of all law -- that of the Constitution. But the years brought about a doctrine that such decisions must be tentative and subject to judicial cancellation if experience fails to verify them. The result is that constitutional precedents are accepted only at their current valuation and have a mortality rate almost as high as their authors.

“When high self-needs are combined with the deprivation of physical affection, the result is self-interest and high rates of narcissism.”

James W. Prescott (1930) American psychologist

"Body Pleasure and the Origins of Violence" (1975)
Context: When high self-needs are combined with the deprivation of physical affection, the result is self-interest and high rates of narcissism. Likewise, exhibitionistic dancing and pornography may be interpreted as a substitute for normal sexual expression.

“Special Forces” Innovation: How DARPA Attacks Problems (2013)
Context: Over the past 50 years, the Pentagon’s Defense Advanced Research Projects Agency (DARPA) has produced an unparalleled number of breakthroughs. Arguably, it has the longest-standing, most consistent track record of radical invention in history. Its innovations include the internet; RISC computing; global positioning satellites; stealth technology; unmanned aerial vehicles, or “drones”; and micro-electro-mechanical systems (MEMS), which are now used in everything from air bags to ink-jet printers to video games like the Wii. Though the U. S. military was the original customer for DARPA’s applications, the agency’s advances have played a central role in creating a host of multibillion-dollar industries.
What makes DARPA’s long list of accomplishments even more impressive is the agency’s swiftness, relatively tiny organization, and comparatively modest budget. Its programs last, on average, only three to five years.

“In our zeal as revolutionists we try to move ahead as fast as possible, clearing the way, but knowing we must draw our sustenance from the mass and that it can advance more rapidly only if we inspire it by our example.”

Ernesto Che Guevara (1928–1967) Argentine Marxist revolutionary

Man and Socialism in Cuba (1965)
Context: The road is long and full of difficulties. At times we wander from the path and must turn back; at other times we go too fast and separate ourselves from the masses; on occasions we go too slow and feel the hot breath of those treading on our heels. In our zeal as revolutionists we try to move ahead as fast as possible, clearing the way, but knowing we must draw our sustenance from the mass and that it can advance more rapidly only if we inspire it by our example.
