Logic in Islamic philosophy

Logic played an important role in early Islamic philosophy, making logic in Islamic philosophy an important branch of study in the history of logic....
. He argued that because God is usually seen as rational, rather than arbitrary, his behaviour in normally causing events in the same sequence (ie, what appears to us to be efficient causation) can be understood as a natural outworking of that principle of reason, which we then describe as the laws of nature. Properly speaking, however, these are not laws of nature but laws by which God. chooses to govern his own behaviour (his autonomy, in the strict sense) - in other words, his rational will.

However, Al-Ghazali does express support for a scientific method

The Deliverance From Error

The autobiography

An autobiography is a biography written by its subject . The term was first used by the poet Robert Southey in 1809 in the English language Periodical publication Quarterly Review, but the form goes back to antiquity....
 Ghazali wrote towards the end of his life, The Deliverance From Error (Al-munqidh min al-?alal; several English translations) is considered a work of major importance.

Though appreciating what was valid in the first two of these, at least, he determined that all three approaches were inadequate and found ultimate value only in the mystical experience and insight (the state of prophecy or nubuwwa) he attained as a result of following Sufi practices. William James
William James

William James was a pioneering American psychology and philosophy trained as a medical doctor. He wrote influential books on the young science of psychology, educational psychology, psychology of religion experience and mysticism, and the philosophy of pragmatism....
, in Varieties of Religious Experience, considered the autobiography an important document for "the purely literary student who would like to become acquainted with the inwardness of religions other than the Christian" because of the scarcity of recorded personal religious confessions and autobiographical literature from this period outside the Christian tradition.

In this work, Al-Ghazali expresses support for mathematics as an exact science, but argues that it cannot be used as a form of proof for religious or metaphysical doctrines due to their non-physical nature. He argues that religion and metaphysics are not in need of mathematics in the sense that poetry

 can be mastered without any knowledge of mathematical sciences. He also argues that every discipline has its own experts and that an expert in one discipline, in this case mathematics, may fail miserably in other disciplines, in this case religion and metaphysics. However, al-Ghazali sees the practical usefulness of mathematics and condemns those who reject the mathematical sciences:

The Revival of Religious Sciences

Another of Ghazali's major works is The Revival of Religious Sciences ( Ihya al-Ulum al-Din or Ihya'ul Ulumuddin). It covers almost all fields of Islamic religious sciences
Islam and science

The relationship between science and Islam is a matter of controversy.

Thus nature is completely dependent on God, which is consistent with other Ash'ari Islamic ideas on causation

. While it is not widely agreed that Al-Ghazali himself intended to "shut the door of ijtihad" completely and permanently, such an interpretation of Al-Ghazali's work is believed to have led Islamic societies to be "frozen in time". Works of critics of Al-Ghazali (such as Ibn-Rushd, a rationalist), as well as the works of any ancient philosopher, are believed to have been forbidden in these "frozen societies" through the centuries. As a result, all chances were lost to gradually revitalize religion - which may have been less painful had it been spread over a period of centuries.

Whether the actual outcome of "freezing Islamic thinking in time" was the goal of Al-Ghazali is highly debatable. While he himself was a critic of the philosophers, Al-Ghazali was a master in the art of philosophy and had an immense education in the field. After such a long education in philosophy, as well as a long process of reflection. But only taking Al-Ghazali's final conclusions, while lacking a comparable education (and a reflection process) in the area, and as a result being unable to trace Al-Ghazali in his thought process, only exacerbates the probability of the misuse of Al-Ghazali's conclusions.

This traditional view, however, has been disputed by recent scholarship, which has shown that scientific and philosophical activity continued to flourish in the Islamic world long after him. For example, Dimitri Gutas and the Stanford Encyclopedia of Philosophy

 curriculum. Emilie Savage-Smith has also shown that Al-Ghazali was a source of encouragement for the study of medicine in medieval Islam, and that his support for the study of anatomy was influential in the rise of dissections carried out among Muslim physicians in the 12th and 13th centuries.

Iqbal Latif holds Al-Ghazali responsible for the decline of logic, reason and tolerance in the Islamic world.. He continues "ignorance about Islam and calculated animosity with deep historic roots on the part of a minority in the West, as well as our failure to defend the true values of Islam, are the reason for the increasing wave of Islamophobia. Unfortunately, however the true values are rarely ever discussed freely, during the glorified ‘Golden Age’ there was particularly strong tradition of rationalists, the Mutazilites. They stressed a human being’s inherent free will countering the predestinarians, who taught that everything was foreordained. The Mutazilites carefully cultivated an ‘enlightened moderation’ and allowed for the growth of knowledge and in their active promulgation and acceptance of Science as a part of the religion doctrine they brought to the Islamic world her Golden Age. This guidance to coexist was advanced by the renowned thinkers such as Avicenna, Al-Raazi, Al Ma’ari and Omar Khayyam; each of whom would later be remembered for the striking global contribution to the field of art, science and logic. The decline set in when the puritan Al-Ghazali began to undermine this rationalistic tradition and instead push for dogma over thought, obedience over free will and the primacy of doctrine. It was the beginning of the end as Al-Ghazali strove to put a stop to the tradition that had cultivated the greatest of the Islamic thinkers and instead stifle the unbridled creativity of the Islamic world."

Iqbal Latif believes that thus the civilization of Islam began to falter as ‘Destiny’ persevered over reason and logic-and Lenient ecclesiastical and priestly control once again tightened over the free Muslim people. With the will of Allah sufficing to explain everything risk no longer matter and Muslim commerce began to dramatically suffer. The banking and finance capitals that could have emerged in the coastal cities and regions of Alexandria, the Yemen and Sumatra, as rivals to Europe were stemmed in their infancy. Any belief that employs “guardians of truth’’ on shaping of landscape of intellect will implode. It is said that ‘Crutches of faith are introduced when reason sink exhausted.’ It is an paradox that when curtain of dogma was descending within the Islamic lands killing free thinking it was slowly and steadily rising in Italy and northern Europe.

," Aquinas embraced non-Christian philosophers and incorporated ancient Greek, Latin and Islamic thought into his own philosophical writings.

"A careful study of Ghazali's works will indicate how penetrating and widespread his influence was on the Western medieval scholars.

In addition, Aquinas' interest in Islamic studies could be attributed to the infiltration of ‘Latin Averroism
