Every Israelite has a duty to study whether he is poor or rich, whethe — Maimonides

"An artisan busies himself with his work for three hours each day and spends nine hours in study."

"The third class of evils comprise those which everyone causes to himself by his own action. This is the largest class, and is far more numerous than the second class. It is especially of these evils that all men complain,—only few men are found that do not sin against themselves by this kind of evil. ...This class of evil originates in mans vices, such as excessive desire for eating, drinking, and love; indulgence in these things in undue measure, or in improper manner, or partaking of bad food. This course brings diseases and afflictions upon the body and soul alike."

"Aristotle was guided by that which appears to be the nature of things. The Ashariyah refused to ascribe to God ignorance about anything... they preferred to admit the above-mentioned absurdities. The Mutazilites refused to assume that God does what is wrong and unjust; on the other hand, they would not contradict common sense and say that it was not wrong to inflict pain on the guiltless, or that the mission of the Prophets and the giving of the Law had no intelligible reason. They likewise preferred to admit the above-named absurdities. But they even contradicted themselves, because they believe on the one hand that God knows everything, and on the other that man has free will. By a little consideration we discover the contradiction."

"A person who lives in a place where the norms of behavior are evil and the inhabitants do not follow the straight path should move to a place where the people are righteous and follow the ways of the good.If all the places with which he is familiar and of which he hears reports follow improper paths, as in our times, ... he should remain alone in seclusion. ...If they are wicked and sinful and do not allow him to reside there unless he mingle with them and follow their evil behavior, he should go out to caves, thickets, and deserts."

"Abraham ... was sunk in Ur of the Chaldees among foolish idolaters. His father and mother and all the people worshipped the stars. ... He knew that all were mistaken and that what caused them to err was worship of the images which drove the Truth out of their minds. ... It was proper to destroy and smash the idols so that the people should not err by them like those who think there is no god save images."

"Teach your tongue to say "I do not know" and you will progress."

"The absolute requisites for the study of this work... are a knowledge of algebra to the binomial at least, plane and solid geometry, plane trigonometry, and the most simple part of the usual applications of algebra to geometry. ...A. De Morgan. London July 1, 1836"

"A free people will always refuse to put up with preventable poverty. If freedom is to be saved and enlarged, poverty must be ended. There is no other solution. The problem of how to prevent these three forces from coming into head-on collision is the principal study of the more politically conscious Conservative leaders. How can wealth persuade poverty to use its political freedom to keep wealth in power? Here lies the whole art of Conservative politics in the twentieth century."

"A clear prediction in an area undergoing vigorous study permits doctrines to be subject to disproof. The last posture a bureaucratic religion wishes to find itself in is vulnerability to disproof, where an experiment can be performed on which the religion stands or falls."

"Spencer argued in a very articulate way for the communality of these processes of self-organization, and used his ideas to make a theory of sociology. However, he was not able to put these ideas into mathematical form or argue them from first principles. And no one else has, either — doing so is perhaps the central problem in the study of complex systems."

"The commercial exploitation of the web has become a growing facet of the world economy, particularly in the last several years. In June 1999 NUA Internet Surveys estimated that 179 million people are connected to the Internet worldwide. A recent study by the sponsored by estimated that the "Internet Economy" generated $300 billion in revenue in the United States alone."

"In biology the Cartesian view of living organisms as machines, constructed from separate parts, still provides the dominant conceptual framework. Although Descartes simple mechanistic biology could not be carried very far and had to be modified considerably during the subsequent three hundred years, the belief that all aspects of living organisms can be understood by reducing them to their smallest constituents, and by studying the mechanisms through which these interact, lies at the very basis of most contemporary biological thinking. This passage from a current textbook on modern biology is a clear expression of the reductionist credo: One of the acid tests of understanding an object is the ability to put it together from its component parts. Ultimately, molecular biologists will attempt to subject their understanding of cell structure and function to this sort of test by trying to synthesize a cell."
