The Islamic Kalam Argument: Burhan al-Imkan

Session 6 — Hypothetical Propositions and the Square of Opposition (Al-Tanaqud)

Listen in EnglishRead aloud by your device — pick a speed:

The complete toolkit, assembled: Sessions 5 and 6 together give you the complete toolkit for propositions. Now you can form them, classify them, relate them, flip them, and use them.

Session 7 builds on this: Session 7 will build the syllogism from these propositions. Here is the application — the classical Islamic Kalam argument, using only the tools of Sessions 5 and 6.

Step 1 — set up the disjunction: The question: is Allah's existence Wajib (necessary) or Mumkin (contingent)? Step 1: set up a Munfasila Haqqiyya: "Either Allah's existence is Wajib (necessary) or it is Mumkin (contingent)" — these are the only two options, and exactly one must be true.

Step 2 — prove by elimination: Step 2: prove by elimination. If Allah's existence were Mumkin, then it would require a cause (Muttasila Haq): "If Allah's existence were Mumkin, then it would require a cause."

The chain to the contradiction: "If it required a cause, then something is prior to Allah" (Muttasila Haq). "If something were prior to Allah, then Allah is not the First Cause" — this contradicts the proven [E] proposition "Nothing is prior to Allah".

Step 3 — apply Tanaqud: Step 3: apply Tanaqud. The conclusion "Allah is not the First Cause" contradicts [E] "Nothing is prior to Allah".

Therefore not Mumkin: Since [E] is proven, [I] "Something is prior to Allah" is false. Therefore Allah's existence cannot be Mumkin.

Conclusion: Allah's existence is Wajib: Conclusion: the Munfasila is reduced to one option — Allah's existence is Wajib. Q.E.D.

The classical Burhan al-Imkan: This is the classical Burhan al-Imkan — the argument from contingency — used by Mulla Sadra and Allama Tabataba'i, built entirely from the tools in Sessions 5 and 6.
