For 2,500 years, Western thought has treated contradiction as catastrophic.
From Aristotle’s law of non-contradiction to modern formal systems, logic has operated under one sacred assumption: a statement cannot be both true and false.
But what if that assumption is wrong?
In my latest Singularity. FM conversation, I sit down with Graham Priest — one of the world’s leading philosophers of logic and the foremost defender of *dialetheism* — the view that some contradictions are true.
We explore:
• Why the liar paradox still unsettles logicians • How paraconsistent logic blocks “explosion” • Whether classical logic is incomplete rather than universal • What Buddhist philosophy understood about contradiction centuries ago • And whether AI systems may require non-classical logics to model human reasoning.
This isn’t an abstract academic debate.
If contradictions can be true, then the foundations of logic, mathematics, rationality — and perhaps artificial intelligence — may need rethinking.
For those working in AI, engineering, or technology, this conversation challenges assumptions you may not even realize you’re making.
For philosophers, it unsettles what many believe is settled.
And for anyone interested in the future of thought itself, this discussion is essential.
