O princípio de não contradição

Abstract

It is common to have a diminutive notion of the principle of non-contradiction, since normally it is only posited as a logical principle, but it is above all an ontological principle, the very ulterior manifestation of being. Indeed, it will help us answer the central question: how does being manifest itself in the multiplicity of entities? In this way, it is mostly necessary to present the manifestation of being through its ontological principle in the ontological, ontic and gnosiological planes of the real. From this, to clarify the impossibility of demonstrating the principle of non-contradiction and how this leads to the principle of the excluded middle; to explain the principle of identity as the synthesis and affirmation of thought, establishing the coincidence between being and thinking; and also to relate the principle of non-contradiction with essential and accidental semantic predication. For this, a qualitative approach is used with a bibliographic character of descriptive nature, making use of the doctrinal analysis. As a result, the presence of the same principle in beings of all natures is perceptible. Concluding that being, through the principle of non-contradiction, manifests itself in the multiplicity of entities.
