“The progress of human knowledge depends on maintaining that touch of scepticism even about the most "unquestionable" truths. A century ago, Darwin's theory of evolution by natural selection was regarded as scientifically unshakeable; today, most biologists have their reservations about it. Fifty years ago, Freud's sexual theory of neurosis was accepted by most psychiatrists; today, it is widely recognized that his methods were highly questionable. At the turn of this century, a scientist who questioned Newton's theory of gravity would have been regarded as insane; twenty years later, it had been supplanted by Einstein's theory, although, significantly, few people actually understood it. It seems perfectly conceivable that our descendants of the twenty-second century will wonder how any of us could have been stupid enough to have been taken in by Darwin, Freud or Einstein.”

“Nearly fifty years ago… Douglas McGregor launched a debate over how to manage The Human Side of the Enterprise. By comparing what he called Theory X and Theory Y perspectives, he challenged the management profession to reexamine its assumptions about the motivations employees bring to their jobs. The question was: Could employees be trusted and empowered to do good work, or did they have to be closely directed, monitored, and controlled to act in the interests of the firm? While McGregor’s Theory Y sparked important innovations in human resource practices, it did not challenge fundamental assumptions underpinning the 20th Century organizational model. If, as is widely recognized, human capital and knowledge are the most important sources of value for the 21st Century organization, then fundamental assumptions about the relationship between work and organizations will also need to be challenged.”

“According to the most influential twentieth-century philosopher of science, Karl Popper, a theory is scientific only in so far as it is falsifiable, and should be given up as soon as it has been falsified. By this standard, the theories of Darwin and Einstein should never have been accepted.”

“Half a century ago in Holism and Evolution Jan Smuts tried to synthesize Darwin's evolutionary theory, Einstein's physics, and his own insights to account for the evolution of mind as well as matter. Wholeness, Smuts said, is a fundamental characteristic of the universe—the product of nature's drive to synthesize.”

“Of course, science lives by confusing theories, but what were accepted as 'theories' even by the many professional psychologists and psychiatrists were very poor limitations of what physical scientists call a theory.”

“New truths in science are often condemned and 25 years ago it was very common and very popular for preachers to sneer at the evolution theory, but to-day it is no longer sneered at, for there is arising in all intelligent minds who have candidly examined the evidence the conviction that this was the method of creation, and no scientist of note to-day denies it.”

“Complexity has always been difficult to resolve and to understand. Evolutionary biologists were among the first scientists to recognize this problem, when they dug their way toward new theories about evolution. They discovered that matter does not lack purpose.”
