The Rule of Explosion can be symbolised by the sequent:
- $\bot \vdash \phi$
Proof
By the tableau method of natural deduction:
| Line | Pool | Formula | Rule | Depends upon | Notes | |
|---|---|---|---|---|---|---|
| 1 | 1 | $\bot$ | Premise | (None) | ||
| 2 | 1 | $\phi$ | Rule of Explosion: $\bot \EE$ | 1 |
