This entry outlines the role of the Law of Non-Contradiction (LNC), or Principle of Non-Contradiction (PNC), as the foremost among the first (indemonstrable) principles of Aristotelian philosophy and its heirs, and depicts the relation between LNC and LEM (the law of excluded middle) in establishing the nature of contradictory and contrary ...
The law of non-contradiction is a rule of logic. It states that if something is true, then the opposite of it is false. ... The law of non-contradiction is found in ancient Indian logic as a rule in the Shrauta Sutras, the writing of Pāṇini, [3] and the Brahma Sutras attributed to Vyasa. It was later elaborated on by medieval commentators ...
The Law of Non-Contradiction applies universally in formal logic, but its application in real-life situations must consider context. For instance, moral or ethical dilemmas often involve contextually dependent contradictions where the right course of action might vary based on specific circumstances.
The Law of Non-Contradiction (A is not non-A): a statement cannot be both true and false at the same time and in the same respect This is a basic law of logic. As an example, this statement would say that a table cannot be both made entirely of wood and not made entirely of wood. A commonly
law of non-contradiction, on some terminology—betray a conception of possibil-ity that is ultimately rooted in metaphysics, not in the linguistic competence that should guide our work in the locked room. It is the business of metaphysics, not of logic, to legislate on whether an object can ever be indeterminate, or overdetermi-
the law of non-contradiction. 2 Non-Apriorism in Logic Despite the influence of Quine (1953) and Putnam (1979), the view that theory choice in logic proceeds via non-apriori terms is far from universally accepted. In this section we provide a defence of non-apriorism in logic.4 To motivate logical non-apriorism, we will critically assess some ...
The law of non-contradiction is a fundamental principle in classical logic stating that contradictory statements cannot both be true at the same time. This principle asserts that if one statement is true, then its negation must be false, which underlies the consistency of logical reasoning and argumentation. Understanding this law is essential for distinguishing between tautologies ...
The law of non-contradiction says, I guess, that for any P, P is incompatible with not-P. But if you deny this law, you aren't committed to say that (1) for any P, P is compatible with not-P. ... Most logic breaks down under contradictions because you can prove anything from it.
The law of non-contradiction is a fundemental law, which can be used in our daily lives. This law can provide truth, regardless of physical objects, philosophy, religion, or action. I wanted to share this law, in hopes to provide another tool for your critical thinking skills. ... Logic is the study of the anatomy and physiology of arguments ...
Regarding the Law of Non-Contradiction and dialectic logic, Zacharias shares his encounter with an Eastern professor. As the professor waxed eloquent and expounded on the law of non-contradiction, he eventually drew his conclusion: "This either/or logic is a Western way of looking at reality. The real problem is that you are seeing ...
The aim of this book is to present a comprehensive debate about the Law of Non-Contradiction (LNC), from discussions as to how the law is to be understood, to reasons for accepting or re-thinking the law, and to issues that raise challenges to the ...

In classical logic, the law of non-contradiction is the second of three classic laws of thought. It states that contradictory statements cannot both be true in the same sense at the same time.¹ The law of non-contradiction, along with its complement, the law of excluded middle, are correlates of the law of identity. Aristotle (as pictured) was one of the main writers of classical logic, among ...
the law of non-contradiction (LNC) is non-trivially unprovable. The law of contradiction just follows logically from the normal semantic of contradictions, conjunctions and negations. According to the normal semantic of English, a contradiction is the conjunction of two terms, one the negation of the other. Symbolically: Φ ∧ ¬Φ
The law of non-contradiction is a tautology. The law of non-contradiction (LNC) is a fundamental principle in logic, stating that a proposition cannot be both true and false simultaneously. This principle is expressed as the tautology ¬(p ∧ ¬p), indicating that contradictory propositions cannot coexist.
There is widespread acknowledgement that the law of non-contradiction (LNC) is an important logical principle. However, there is less-than-universal agreement on exactly what the law amounts to. This lack of clarity is brought to light by the emergence of paraconsistent logics in which contradictions are tolerated: from the point of view of ...
The law of non-contradiction states that a proposition and its negation cannot both be true in the same sense at the same time. It is a fundamental principle of logic that asserts something cannot both be and not be at the same time and in the same respect.
The Law of Non-Contradiction is a law in logic which states that for any sentence or proposition, it and its negation are not both true. In other words, the law states that there are no true contradictions. The Law of Non-Contradiction is often stated as the axiom: ¬(φ ∧ ¬φ).
