Averroes: Defending Philosophy and Harmonizing Reason and Revelation

Suppose your religious community starts to suspect that philosophy corrupts faith and should be banned.
Ibn Rushd (Averroes) writes what is essentially a legal opinion arguing that, properly done, philosophy is not just allowed by Islam—it is required for some.

Averroes, working in al‑Andalus (Islamic Spain), responds to al‑Ghazali from a different angle. In his Decisive Treatise (Faṣl al‑Maqāl), he asks whether studying philosophy and logic is permitted, forbidden, or commanded by Islamic law. His answer: the Qurʾan itself commands reflection on creation, and philosophy is nothing but disciplined reflection, so for those capable of it, philosophical inquiry is a religious duty. He is not promoting a secular reason against faith; he is arguing that reason, done right, serves understanding of revelation. Averroes distinguishes between different classes of people and different modes of discourse. Some understand through rhetorical images, others through dialectical argument, and a few through demonstrative proofs. Scripture speaks in ways accessible to all, often using metaphor. Philosophers use demonstration, which can uncover meanings in the text that are not obvious on the surface. When there is apparent conflict between a demonstrative truth and a literal reading of scripture, Averroes says the text should be interpreted allegorically. Truth, as he memorably puts it, does not contradict truth. This has sometimes been misread as a “double truth” doctrine—one truth for philosophy, another for religion. Averroes himself rejects that. For him there is one reality and one ultimate truth, but different audiences and methods. His stance in the reason–revelation debate is thus a mediated one: stricter than al‑Ghazali (who is ready to condemn certain philosophical doctrines as unbelief), but not a proto‑secularist. He wants law scholars (fuqahāʾ) to see that philosophy has at least as strong a claim to legitimacy as jurisprudence, because both are ways of obeying the divine command to reflect.

“Our purpose in this treatise is to investigate, by way of a legal inquiry, whether the study of philosophy and the logical sciences is permitted by the Law, or prohibited, or commanded, either by way of recommendation or obligation.

We say that, if the activity of philosophy is nothing more than study of existing beings and reflection upon them in order to know the Creator, may He be exalted, through them, then the Law has encouraged and urged this, for it has called attention to the consideration of beings and exhorted us to reflect on them. … Thus it is clear that this activity is either obligatory or recommended by the Law.”

— Averroes (Ibn Rushd), Decisive Treatise, opening sections, standard English translation (wording approximate)

Averroes frames the whole question as a matter of fiqh, legal reasoning. That is a strategic move: he’s speaking in the language jurists respect. He then defines philosophy simply: study of beings in order to know the Creator through them. On that definition, he can point to Qurʾanic verses that urge believers to “reflect” on the heavens, the earth, and their own souls. If God commands reflection, and philosophy is just refined reflection, then at least for qualified people, it must be permitted and even commanded. The last line is punchy: philosophical activity is “either obligatory or recommended.” That undercuts the idea that philosophers are dangerous outsiders. At the same time, Averroes’s careful audience‑splitting preserves the authority of the Law for most people. Not everyone should read allegorical interpretations or advanced arguments; mishandled, they can confuse or mislead. That elitism is part of his solution: it allows deep rational work without demanding that every believer become a philosopher.

Think about contemporary debates over evolutionary theory in religious communities. An Averroist approach would say: if demonstrative scientific inquiry shows that life developed through evolution, and if that inquiry meets high standards of evidence, then apparent conflicts with scripture are to be resolved by non‑literal interpretation. Religious leaders might still teach creation stories at a more literal level to children or laypeople, while theologians and philosophers work out harmonizing readings in the background. The claim “truth does not contradict truth” then becomes a principle: authentic science and authentic revelation cannot ultimately clash, though our interpretations of either might.

If you split audiences and allow allegorical readings for the elite, do you risk creating two religions—one philosophical, one popular? Or is that a realistic way to protect both intellectual honesty and communal stability?
