How to Understand Politics: What the Humanities Can Say to Science (2007)
The quantity of anthropological data discovered by scientists now exceeds any individual’s ability to assimilate it. The division of labor, including intellectual labor, begun thirty thousand years ago in the Paleolithic, has become an irreversible phenomenon, and there is nothing that can be done about it. Like it or not, we have placed our destiny in the hands of the experts. A politician is, after all, a kind of expert, if self-styled. Even the fact that competent experts must serve under politicians of mediocre intelligence and little foresight is a problem that we are stuck with, because the experts themselves cannot agree on any major world issue. A logocracy of quarreling experts might be no better than the rule of the mediocrities to which we are subject. The declining intellectual quality of political leadership is the result of the growing complexity of the world. Since no one, be he endowed with the highest wisdom, can grasp it in its entirety, it is those who are least bothered by this who strive for power.
One Human Minute (1986)
"Man alone, of all creatures of earth, can change his thought pattern and become the architect of his destiny." Actually said by Spencer W. Kimball, twelfth president of The Church of Jesus Christ of Latter-day Saints, in his Miracle of Forgiveness (1969), p. 114. This predates any of the misquotations.
Other forms: "The greatest discovery of my generation is that human beings can alter their lives by altering their attitudes of mind." This is also misattributed to Albert Schweitzer.
James did say: "As life goes on, there is a constant change of our interests, and a consequent change of place in our systems of ideas, from more central to more peripheral, and from more peripheral to more central parts of consciousness."
Misattributed
Context: Man alone, of all the creatures on earth, can change his own patterns. Man alone is the architect of his destiny. The greatest revolution in our generation is the discovery that human beings, by changing the inner attitudes of their minds, can change the outer aspects of their lives … It is too bad that most people will not accept this tremendous discovery and begin living it.
