Greek Philosophy in Arabic: Its Encounter with Kalām

1. The historical meeting of kalām and philosophy

ثم لما نقلت الفلسفة عن اليونانية إلى العربية
Then, when philosophy was translated from Greek into Arabic.

Kalām investigates theological doctrines, establishes their proofs, and responds to objections. Earlier discussions were largely structured around revealed texts and controversies arising within Islamic scholarship. The translation of Greek philosophical works into Arabic introduced additional questions, vocabularies, and methods of argument.

This change was gradual: translation, study, debate, selective adoption, and critique did not occur all at once. Employing a philosophical term does not entail accepting every philosophical doctrine; likewise, rejecting a doctrinal claim does not mean all inquiry conducted in that field is useless.

For example, the term cause (ʿillah) can serve as a tool of reasoning. Adopting a particular theory about the causal relation between God and the world is a separate theological commitment.

2. Two prominent Sunni theological approaches

والماتريدية يخالفون الأشعرية في بعض المسائل، منها التكوين
The Māturīdīs differ from the Ashʿarīs on certain matters, among them takwīn.

Within Sunni scholarship, Ashʿarī and Māturīdī approaches were influential in organizing and defending theological positions. The first is associated with Abū al-Ḥasan al-Ashʿarī, and the second with Abū Manṣūr al-Māturīdī. They share many foundational commitments while differing in the precise formulation of some issues.

A legal school, a theological method, and every view of a particular scholar should not be treated as interchangeable. Each dispute requires identifying the exact propositions and terms employed by the participants.

For example, discussions of takwīn, the believer who follows authority, and the moral qualities of acts are best approached as distinct questions with specific arguments rather than as mere labels for groups.

Taghlīb: Some later authors used the more familiar Ashʿarī label for both scholarly approaches. That inclusive usage does not erase their distinct formulations.

3. Takwīn and divine power

قال الأشعري: راجع إلى القدرة، وقال الماتريدية: صفة أخرى
The Ashʿarī account relates it to power, whereas the Māturīdī account treats it as another attribute.

Takwīn concerns the divine attribute associated with bringing things into being. A principal question in Ashʿarī–Māturīdī discourse is whether this relation is explained under divine power or treated as a distinct attribute of creating.

The distinction is not simply a change of vocabulary: it touches the classification of divine attributes, their relation to created things, and the difference between an eternal attribute and a temporal effect. Neither approach should be simplistically described as denying God’s creatorship.

Example: “God is powerful” and “God creates” are both affirmations. The technical dispute concerns how the two statements relate within a systematic account of divine attributes.

4. Takfīr of people of the qiblah

ومنها تكفير أهل القبلة
Another issue concerns declaring people of the qiblah unbelievers.

People of the qiblah broadly refers to those identifying with Islam and praying toward its direction of worship. The theological question here is whether, and under what conditions, an erroneous doctrinal position may be deemed to remove someone from Islam. Classical formulations vary on the scope and application of this matter.

It is essential not to collapse every scholarly error, innovation, and denial of a foundational doctrine into one category. Assessing an actual person may require attention to the meaning of the claim, implications, clarification, and relevant impediments.

This lesson identifies a historical difference in theological formulations; it does not issue judgments of unbelief against contemporary persons or communities.

5. The faith of one who follows authority

ومنها إيمان المقلد
One of the disputed questions is the faith of the muqallid.

A muqallid may be a person who accepts a belief on a trusted scholar’s or community’s authority without independently constructing every proof. The problem of the muqallid’s faith does not ask whether evidence is valuable; it asks how correct belief is assessed when systematic demonstration is absent.

Two aspects must be separated: holding a true belief and possessing the ability to explain its formal proof. An inability to present a sophisticated argument does not, by itself, establish an absence of inward conviction. Learning the reasons for belief still has genuine intellectual value.

This is a distinct discussion about faith, understanding, and inference; it should not be confused with takwīn or the morality of actions.

6. Qualifying statements about one’s faith

ومنها الاستثناء جوزه الأشعرية
The question of qualification is mentioned, with allowance attributed to Ashʿarīs.

Exception in statements of faith is discussed through expressions such as “I am a believer, God willing.” A formulation may be heard as uncertainty about present faith, while the speaker may intend reference to the future, final outcome, acceptance, or humility.

Before classifying the statement, one must separate the words as uttered from the meaning intended in context. The phrase “God willing” does not necessarily indicate one identical psychological or doctrinal attitude in every use.

This is a distinct theological debate. Here it serves to identify one of the matters for which differences in Ashʿarī and Māturīdī exposition have been reported.

7. Moral goodness and badness of acts

ومنها القبح والحسن في الأفعال
Another matter is the goodness and badness of human actions.

The debate over ḥusn and qubḥ requires distinguishing what people naturally approve or dislike, what is beneficial or harmful, and what is subject to religious praise, blame, reward, or punishment. Without these distinctions, “reason knows good and evil” remains ambiguous.

For example, truthfulness supports social trust. But “What religious ruling and ultimate accountability attach to an act?” asks an additional question. Ashʿarī and Māturīdī explanations differ in how they assign roles to reason and revelation in these matters.

The dispute is neither simply the complete rejection of reason nor the denial of revelation. A fair comparison identifies the exact domain of moral evaluation and the conditions of religious obligation.

8. Divine acts and rational judgments

قال الماتريدية: لا يجوز من الله ما يستقبحه العقل
The Māturīdī formulation denies attributing to God what reason judges repugnant.

In discussions of divine acts, possibility, actual occurrence, and rational permissibility need careful distinction. One approach may reject attributing an act to God because it is considered incompatible with perfection; another analyzes the relationship between rational judgment and revealed norms differently.

To interpret “God does not perform an evil act” adequately, the relevant sense of “evil” must be specified. One cannot automatically import changing human tastes and interests into claims about divine action.

A necessary discipline is to separate established creedal affirmations, the arguments advanced for them, and a school’s particular technical formulation.

9. Wisdom and purpose in divine action

قد يراعي الله سبحانه المصلحة تفضلا
God may consider benefit as an act of grace.

Wisdom (ḥikmah), benefit (maṣlaḥah), and purpose (gharaḍ) are not identical terms. Creatures often act to obtain something they lack; arguments about divine wisdom must avoid suggesting that God is dependent upon an external need or coercion.

Ashʿarī–Māturīdī discussions ask whether divine action is explained through purpose in a technical sense. Denying an imposed external objective is not necessarily denying wisdom; affirming the consideration of benefit need not mean God is under an externally imposed obligation.

This distinction connects with the earlier debate about aṣlaḥ and the three brothers, but the present issue is the broader interpretation of divine acts and attributes.

The sending of messengers illustrates the same distinction: prophetic guidance benefits people, but identifying this benefit does not impose an external duty on God.

10. Greek philosophy enters Arabic scholarship

وخاض فيها الإسلاميون، وحاولوا الرد على الفلاسفة فيما خالفوا فيه الشريعة
Muslim scholars engaged these discussions and sought to answer philosophical claims they saw as contrary to revelation.

When Greek philosophical texts entered Arabic scholarship, Muslim scholars did more than translate them. They studied the questions, tested forms of reasoning, and challenged conclusions they considered unacceptable. Reading philosophy, using its vocabulary, and accepting a particular doctrine are different acts.

The encounter influenced the agenda of kalām. Older issues were reformulated in a broader rational idiom, and new questions became prominent: the beginning of the world, causality, and the nature of material and immaterial things.

This history cannot be captured adequately by saying scholars adopted everything or rejected everything. Each conceptual tool and substantive proposition requires separate evaluation.

11. Stages in the translation movement

وأول من نقلها خالد بن يزيد بن معاوية
An early stage of its transmission is associated with Khālid ibn Yazīd ibn Muʿāwiyah.

Accounts of Greek learning’s transmission into Arabic name several figures and periods. Khālid ibn Yazīd ibn Muʿāwiyah is associated in some historical reports with early patronage; translation activities expanded markedly during the reign of the Abbasid al-Maʾmūn. Ḥunayn ibn Isḥāq is also a prominent name in the history of translators.

These historical attributions do not all have equal evidentiary strength. They should be read as part of a broad chronology, not as a claim that the whole corpus entered Arabic through one individual or in one moment.

Translated material had differing uses: medicine could inform practice, logic could inform disputation, and metaphysical propositions might become subjects of critique.

12. The meanings of falsafah and ḥikmah

والفلسفة: هي الحكمة اليونانية
Here philosophy means Greek wisdom.

Falsafah is connected with the Greek linguistic tradition of “love of wisdom.” Ḥikmah in broader Islamic usage can also mean insight, sound judgment, or wise conduct. The word “wisdom” therefore does not always designate one particular Greek philosophical system.

Philosophical inquiry examines beings, their principles, and relations accessible to rational reflection. This description does not establish that every philosopher’s conclusion is true, nor that every philosophical question is intrinsically invalid.

Example: “What causes a thing to occur?” is a general question. “The universe proceeds necessarily from an eternal cause” is a specific metaphysical answer. The question and the proposed answer must be assessed separately.

Some traditional accounts portray early sages as learning from prophets and explain later errors through flawed transmission or misunderstanding. These are historical claims within the received narrative, not independently established facts that must be treated as certain in every detail.

13. Premises and theological consequences

كقدم العالم، وإيجاب الصانع، ونفي حشر الأجساد، ونفي علم الله سبحانه بالجزئيات
Such as the eternity of the world, necessary causation attributed to the Creator, denial of bodily resurrection, and denial of divine knowledge of particulars.

An argument must be evaluated through its premises as well as its conclusion. If someone moves from observed regularities in the world to the claim that the world is eternal, we must ask what additional assumption bridges observation and eternity.

Classical disputes address the eternity of the world, necessary emanation from the Creator, denial of bodily resurrection, and denial of divine knowledge of particulars. These are not identical propositions and cannot all be assessed by a single undifferentiated argument.

Defending creed through reason requires identifying the exact disputed claim, the evidence advanced for it, and the weakness—if any—in its supporting inference.

14. What is disputed in the eternity of the world?

Qidam al-ʿālam is the thesis that the world, or its underlying reality, has no temporal beginning. Calling the world created is a different kind of claim: it denies that the world is independently self-sufficient or necessary in itself. Detailed arguments engage questions about beginnings, causation, and existence.

Example of reasoning: “We did not observe its beginning” does not establish “It never began.” The first is about the limits of observation; the second asserts a fact about reality.

Terms such as “eternal,” “pre-eternal,” “originated,” and “created” must be defined before the arguments can be fairly compared. Otherwise disputants may appear to disagree while talking past one another.

15. Necessity and divine agency

Ījāb al-ṣāniʿ in this context refers to a metaphysical account in which effects follow from their source with necessity. In contrast, the discussion of a volitional agent (fāʿil mukhtār) stresses the relation of power and will to action.

If an agent’s action is portrayed as the unavoidable output of a natural process with no room for will or choice, the assertion is more than the neutral use of the word “cause”: it becomes a substantive theological theory.

Example: Cloth warming near fire is a physical relation. It does not by itself prove a particular metaphysical theory about divine volition and creation. The limits of analogies between Creator and creature must be observed.

16. Bodily resurrection and knowledge of particulars

Bodily resurrection concerns the reality of embodied human life in the hereafter. Knowledge of particulars asks whether God knows individual persons, times, and events or whether divine knowledge is instead confined to universal structures. Each is a substantive doctrinal issue.

Universal versus particular: “All humans are mortal” is a universal proposition. “What does this individual intend at this moment?” concerns a particular person and state. Knowledge of universals does not, without further argument, entail ignorance of particulars.

These disputes are not merely verbal. They concern how divine knowledge and the reality of the hereafter should be understood in relation to revelation and sound reasoning.

17. How debate shaped kalām

فخلطوا بالكلام كثيرا من الفلسفة؛ ليحققوا مقاصدها، فيتمكنوا من إبطالها
They incorporated much philosophical discussion into kalām to identify its claims and thereby answer them.

To answer philosophical objections, theologians examined premises, defined equivocal words, and exposed invalid inferences. Disputation (munāẓarah) thus involved more than trading conclusions; it became a disciplined examination of the structure of arguments.

A position must be represented accurately before it is refuted. Weakening an opponent’s claim and defeating the weakened version is not a scholarly achievement. Equally, a valid logical principle does not become false simply because someone uses it in a faulty argument.

Example: If a person begins with “Every originated thing has a cause” and draws an unrelated conclusion, the missing or invalid intermediate step needs to be identified.

18. The widening scope of later kalām

أدرجوا فيه معظم الطبيعيات والإلهيات، وخاضوا في الرياضيات
They included much natural philosophy and metaphysics within kalām and also engaged mathematics.

Later kalām expanded to include discussions associated with multiple philosophical disciplines alongside its core doctrinal concerns. This happened partly because arguments about belief were being formulated through questions of nature, existence, possibility, causation, and mathematical illustrations.

The distinction between the objective and an auxiliary discussion is crucial. A logical or physical premise introduced to defend a creed is a means of inquiry; it does not automatically become an article of faith.

Example: “What is a body?” can be a question of natural philosophy. “Can bodiliness be attributed to God?” concerns theological transcendence and divine attributes. The same word must be handled differently at these two levels.

19. Natural philosophy and matter

الطبيعيات: علم يتعلق بأمور يتوقف على مادة في التصور والوجود الذهني والخارجي
Natural philosophy concerns matters dependent upon matter in conception and in mental and external existence.

Ṭabīʿiyyāt (natural philosophy) studies things for which matter is integral to their nature and actual existence. Bodies, motion, change, and physical qualities are representative subjects. This classification belongs to the language of classical philosophical sciences, not to a complete taxonomy of modern academic departments.

Example: To describe an actual wooden plank as a physical object, we cannot detach it from its extension and material constitution.

Such questions become relevant to kalām when theologians examine arguments about bodies, temporal origination, motion, or the composition of physical objects.

20. Metaphysics beyond material conditions

والعلم الإلهي: علم يتعلق بأمور لا يتوقف على مادة في التصور والوجود
Metaphysics concerns matters not dependent on matter for their conception or existence.

In classical classification, ilāhiyyāt (metaphysics) also addresses general notions not tied to conceiving a particular material body, such as being, necessity, cause, and effect. The term does not mean only rituals or devotional theology.

Example: “Is everything that exists necessarily existent?” examines the relationship between being and necessity, not the physical shape of a particular stone or tree.

Although metaphysics and kalām may share questions, their every claim is not thereby identical. A doctrinal conclusion still requires its own assessment against the relevant rational and revealed evidence.

21. Mathematics: conception versus external instantiation

والعلم الرياضي: علم يتعلق بأمور يتوقف على مادة في الوجود دون التصور
Mathematics concerns things requiring matter for external existence but not for conceptualization.

In classical philosophical classification, riyāḍiyyāt (mathematics) examines objects that can be understood independently of a particular material while their concrete external instances appear through a material bearer. A sphere, circle, or quantity helps illustrate the distinction.

In conception: one can investigate an ideal sphere without specifying wood, iron, or any other material.
In external instantiation: a ball placed before us exists as some concrete physical thing.

The point is the difference between requiring material in the concept itself and needing a material instance for a particular physical realization. It does not amount to denying either mathematical truth or concrete objects.

22. The characteristic form of later kalām

وهذا هو كلام المتأخرين
This is the form of discourse known as later kalām.

Later kalām is characterized by a more explicit use of philosophical questions and technical classifications. A theologian might construct premises about being and possibility, critique an account of bodies, or use logic to test the validity of an inference.

Differences between earlier and later styles do not imply that later scholars accepted every philosophical claim, or that early theological argument lacked all rational reasoning. The objective of defending doctrine could remain while the supporting vocabulary, organization, and auxiliary sciences changed.

The essential distinction is between the doctrinal conclusion and the method used to argue for it.

23. Kalām and the foundations of religious sciences

وبالجملة هو أشرف العلوم، لكونه أساس الأحكام الشرعية، ورئيس العلوم الدينية
In summary, kalām is called an eminent science because it underlies religious rulings and holds a foundational place among the religious disciplines.

Kalām is regarded as foundational among the religious sciences because commitment to worship and legal duties presupposes convictions about God, prophethood, and the truth of revelation. Once the authority of those foundations is affirmed, legal details can be studied within their appropriate discipline.

Foundations and branches: The units and conditions of prayer are studied in fiqh. Accepting prayer as divinely prescribed, however, is connected with the authority of God, His Messenger, and revelation.

Calling one discipline “foundational” does not render other sciences unnecessary. Each remains important according to its subject and purpose; the designation identifies the relationship between basic commitments and their further consequences.

24. Certainty and ancillary philosophical questions

The central purpose of theological inquiry is sound understanding of God, assent to prophethood, and a dependable basis for religious obligations. By contrast, disputes over certain auxiliary philosophical details do not automatically define the essential commitments of every believer.

Example: Belief in divine knowledge and power is a foundational theological concern. Accepting one ancient classification of matter or a philosopher’s definition of motion is not thereby a prerequisite of personal faith.

This distinction guards against two errors: treating foundational creed as merely speculative philosophy, and elevating every historical philosophical term into a binding article of religion.

Its central proofs also draw strength from decisive revealed evidence alongside rational inquiry. Historical debate over ancillary philosophical details must not be confused with that foundational authority.

25. Synthesis and transition

The development of kalām can be understood on three connected levels. 1. Doctrinal foundations: convictions concerning God, the divine attributes, and prophethood. 2. Intellectual defense: careful analysis of claims, arguments, and objections. 3. Auxiliary disciplines: selected uses of logic, natural philosophy, metaphysics, and mathematics.

On this account, Ashʿarī–Māturīdī differences are debates within the theological tradition, whereas the translation of Greek philosophy brought engagement with an additional body of questions. These should not be confused as one single controversy.

Against this background, ḥaqāʾiq al-ashyāʾ thābitah raises a distinct foundational issue: how do the realities of things relate to human knowledge? That question bears on the status of philosophical arguments, observation, and theological proof.
