Religious law makes it illegal for the ignorant to drink wine, but int — Avicenna

"The knowledge of anything, since all things have causes, is not acquired or complete unless it is known by its causes. Therefore in medicine we ought to know the causes of sickness and health. And because health and sickness and their causes are sometimes manifest, and sometimes hidden and not to be comprehended except by the study of symptoms, we must also study the symptoms of health and disease. Now it is established in the sciences that no knowledge is acquired save through the study of its causes and beginnings, if it has had causes and beginnings; nor completed except by knowledge of its accidents and accompanying essentials. Of these causes there are four kinds: material, efficient, formal, and final."

"An ignorant doctor is the aide-de-camp of death."

"I [prefer] a short life with width to a narrow one with length."

"Medicine considers the human body as to the means by which it is cured and by which it is driven away from health."

"Those who deny the first principle should be flogged or burned until they admit that it is not the same thing to be burned and not burned, or whipped and not whipped."

"God, the supreme being, is neither circumscribed by space, nor touched by time; he cannot be found in a particular direction, and his essence cannot change. The secret conversation is thus entirely spiritual; it is a direct encounter between God and the soul, abstracted from all material constraints."

"I appeal to all pupils, students and young people, asking you to focus on the horizons that are opening up for you, and which you could only dream of a year ago. Our future will depend on your desire for education and moral values as well as on your entrepreneurial spirit."

"We have created a wealthy society with tens of millions of talented, resourceful individuals who play virtually no role whatsoever as citizens. Bringing these people in — with their networks of influence, their knowledge, and their resources — is the key to creating the capacity for shared intelligence that we need to solve our problems."

"We are shocked when we see educators, timid before criticism and confused about first principles, betray their trust. And we wonder what can be that philosophy of education which believes that young people can be trained to the duties of citizenship by wrapping their minds in cotton wool."

"I cant read ten pages of Steinbeck without throwing up. I couldnt read the proletarian crap that came out in the 30s; again you had sentimentalism — the poor oppressed workers."

"An [hypertext] encyclopaedia will be an overall attempt by the knowledgeable, the learned societies or anyone else, to represent the state-of-the-art in their field. An encyclopaedia will be a living document, as up to date as it can be, instantly accessible at any time. It will contain carefully authored explanations and summaries of the subject, as well as computer-generated indexes of literature. A reference to a paper from the encyclopaedia conveys authority and acceptance by academic society. A measure of a paper’s standing may be conveyed by the number of links it is away from an encyclopaedia."

"One of the first major steps in the direction of modern skepticism came through the victory of Occam over Aquinas in a controversy about language. The statement that modi essendi were replaced by modi significandi et intelligendi, or that ontological referents were abandoned in favor of pragmatic significations, describes broadly the change in philosophy which continues to our time. From Occam to Bacon, from Bacon to Hobbes, and from Hobbes to contemporary semanticists, the progression is clear: ideas become psychological figments, words become useful signs. ... To one completely committed to this realm of becoming, as are the empiricists, the claim to apprehend verities is a sign of . Probably we have here but a highly sophisticated expression of the doctrine that ideals are hallucination and that the only normal, sane person is the healthy extrovert, making instant, instinctive adjustments to the stimuli of the material world."
