Paraconsistent logic has already demonstrated that there are situations in which the principle of non-contradiction is violated, and there are situations in quantum physics that violate the principle of non-contradiction (an example of this is the hypothetical representative of Schrödinger's cat), and the photons With its duality. And also considering the self-reference of some paradoxes such as the liar, which demonstrate that the principle of non-contradiction has limits not only physical but also linguistic. This doesn't mean that it is invalid, it just means that it is not absolute and that it does not apply to everything.
