| name | philosophical-theology |
| description | Philosophical theology — the use of philosophical tools to analyze and evaluate theological claims. Covers classical arguments for and against the existence of God (cosmological, ontological, teleological, moral, evil), the divine attributes (simplicity, omniscience, omnipotence, eternity, impassibility), the relation of faith and reason, religious epistemology, and the boundary between natural theology and revealed theology. Use when a query asks whether a theological claim is rationally defensible, how a divine attribute should be understood, or how philosophical frameworks across traditions have engaged religious questions. |

Philosophical Theology
Philosophical theology is the use of the tools of philosophy — conceptual analysis, argument, inference to the best explanation — to examine theological claims. Its classical questions are about God: does God exist, what is God like, how could we know. Its modern questions also include religious epistemology (how are religious beliefs justified?), religious language (what does God-talk mean?), and the problem of disagreement (what should a believer or nonbeliever do about the persistence of religious disagreement?). The discipline is methodologically neutral: it can be done by believers, by atheists, or by anyone interested in the arguments.

1. Natural theology vs. revealed theology
A classical distinction separates what can be known about God by reason alone from what can only be known through revelation. Natural theology argues for conclusions about God from premises available to any reasoner — the existence of a cosmos that requires explanation, the experience of moral obligation, the intelligibility of nature. Revealed theology begins from claims a community takes as given by God through scripture, tradition, or prophetic experience and works out their implications.
The boundary between the two is contested. Aquinas held that reason can establish the existence of God and some of the divine attributes, but cannot establish the Trinity or the Incarnation without revelation. Maimonides drew a similar line in a Jewish frame, reserving to reason what reason could secure and to prophetic revelation what exceeds it. Al-Farabi and Ibn Sina worked out similar distinctions in the Islamic tradition. Reformation theology, especially in its Barthian twentieth-century version, rejected natural theology entirely; Karl Barth's "Nein!" to Emil Brunner in 1934 is the famous modern rejection, on the ground that natural theology underwrites a God built to human specifications rather than the God who speaks from outside.
2. Classical arguments for the existence of God
Cosmological arguments
Cosmological arguments argue from the existence or order of the cosmos to a cause that explains it. Two major families.
Kalam cosmological argument. Developed by medieval Muslim theologians (especially al-Ghazali), revived in modern analytic philosophy of religion by William Lane Craig. The form:
- Whatever begins to exist has a cause.
- The universe began to exist.
- Therefore the universe has a cause.
Premise (2) is argued philosophically (the impossibility of an actual infinite regress) and empirically (appealing to Big Bang cosmology). Premise (1) is argued as a metaphysical principle. The argument is disputed at both premises.
