Avicenna was a Persian polymath who is regarded as one of the most significant physicians, astronomers, thinkers and writers of the Islamic Golden Age. He has been described as the father of early modern medicine. Of the 450 works he is known to have written, around 240 have survived, including 150 on philosophy and 40 on medicine.His most famous works are The Book of Healing, a philosophical and scientific encyclopedia, and The Canon of Medicine, a medical encyclopedia which became a standard medical text at many medieval universities and remained in use as late as 1650. In 1973, Avicenna's Canon Of Medicine was reprinted in New York.Besides philosophy and medicine, Avicenna's corpus includes writings on astronomy, alchemy, geography and geology, psychology, Islamic theology, logic, mathematics, physics and works of poetry.

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

—  Avicenna

As quoted in Familiar Medical Quotations (1968) by Maurice B. Strauss

„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.“

—  Avicenna

"On Medicine, (c. 1020) http://www.fordham.edu/halsall/source/1020Avicenna-Medicine.html
Context: 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.

„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.“

—  Avicenna

As quoted in 366 Readings From Islam (2000), edited by Robert Van der Weyer
Context: 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.

„The world is divided into men who have wit and no religion and men who have religion and no wit.“

—  Avicenna

This was declared without citation to have been attributed to Avicenna in A Rationalist Encyclopaedia : A Book of Reference on Religion, Philosophy, Ethics, and Science (1950), by Joseph McCabe, p. 43; it was also later wrongly attributed to Averroes in The Atheist World‎ (1991) by Madalyn Murray O'Hair, p. 46. It actually originates as a statement by the atheist Al-Maʿarri, earlier translated into English in A Short History of Freethought Ancient and Modern (1906) by John Mackinnon Robertson, Vol. I, Ch. VIII : Freethought under Islam, p. 269, in the form: "The world holds two classes of men ; intelligent men without religion, and religious men without intelligence."
