Carroll Paradox

Paradox
Modus Ponendo Ponens leads to infinite regress.

Proof
To be proven: $q$.

1. Assume $p \implies q$.

2. Assume $p$.

3. $p \land \left({p \implies q}\right) \vdash q$.

4. From 2 and 1, $p \land \left({p \implies q}\right)$.

5. $\left({p \land \left({p \implies q}\right) \land \left({p \land \left({p \implies q}\right)}\right) \vdash q}\right) \vdash q$.

6. From 4 and 3, $(p \land (p \implies q))\land ((p \land (p \implies q)) \vdash q)$.
