The argument
P1 premise
Whatever begins to exist has a cause.
∀x. Began(x) → (∃y. Causes(y, x))
Grounded by ExNihilo
P2 premise
The universe began to exist.
Began(universe)
Grounded by Ghazali, Craig, Gen1
D1 deduction
Therefore the universe has a cause.
∃y. Causes(y, universe)
From P1, P2
Proof
P3 premise
A cause of all of space and time is itself beyond space and time.
∀y. Causes(y, universe) → Transcendent(y)
Grounded by Craig
C1 conclusion
Therefore the universe has a transcendent cause.
∃y. Causes(y, universe) ∧ Transcendent(y)
From D1, P3
Proof
Objections and replies
O1 objection to P1 answered
Quantum events, such as radioactive decay, seem to begin without a cause.
R1 reply to O1
Quantum events arise within a vacuum governed by physical law, which is not nothing; P1 concerns coming into being from nothing.
O2 objection to P2 answered
The universe might have an infinite past, so it never began.
R2 reply to O2
A series of past events formed by successive addition cannot be actually infinite, since an infinite cannot be traversed one step at a time.
