    The first edition, published in 2001, was titled simply An Introduction to Non-Classical Logic. In 2008, Priest published a substantially expanded and revised second edition under the title An Introduction to Non-Classical Logic: From If to Is. [1] The second edition more than doubled the length of the original text, expanding from 242 to 613 ...

  3. Unconventional warfare - Wikipedia

    en.wikipedia.org/wiki/Unconventional_warfare

    Aside from the earlier definition of warfare that is not conventional, unconventional warfare has also been described as: There is another type of warfare— new in its intensity, ancient in its origin—war by guerrillas, subversives, insurgents, assassins; war by ambush instead of by combat, by infiltration instead of aggression, seeking victory by eroding and exhausting the enemy instead of ...

  4. Non-classical logic - Wikipedia

    en.wikipedia.org/wiki/Non-classical_logic

    Non-classical logics (and sometimes alternative logics or non-Aristotelian logics) are formal systems that differ in a significant way from standard logical systems such as propositional and predicate logic. There are several ways in which this is commonly the case, including by way of extensions, deviations, and variations.

  5. Non-Euclidean geometry - Wikipedia

    en.wikipedia.org/wiki/Non-Euclidean_geometry

    In mathematics, non-Euclidean geometry consists of two geometries based on axioms closely related to those that specify Euclidean geometry.As Euclidean geometry lies at the intersection of metric geometry and affine geometry, non-Euclidean geometry arises by either replacing the parallel postulate with an alternative, or relaxing the metric requirement.

  6. Nonconformity (quality) - Wikipedia

    en.wikipedia.org/wiki/Nonconformity_(quality)

    In quality management, a nonconformity (sometimes referred to as a non conformance or nonconformance or defect) is a deviation from a specification, a standard, or an expectation. Nonconformities or nonconformance can be classified in seriousness multiple ways, though a typical classification scheme may have three to four levels, including ...

    en.wikipedia.org/wiki/Non-conventional_trademark

    A non-conventional trademark, also known as a nontraditional trademark, is any new type of trademark which does not belong to a pre-existing, conventional category of trade mark, and which is often difficult to register, but which may nevertheless fulfill the essential trademark function of uniquely identifying the commercial origin of products or services.

  8. Convention (norm) - Wikipedia

    en.wikipedia.org/wiki/Convention_(norm)

    A convention influences a set of agreed, stipulated, or generally accepted standards, social norms, or other criteria, often taking the form of a custom.. In physical sciences, numerical values (such as constants, quantities, or scales of measurement) are called conventional if they do not represent a measured property of nature, but originate in a convention, for example an average of many ...

  9. Non-normal modal logic - Wikipedia

    en.wikipedia.org/wiki/Non-normal_modal_logic

    A non-normal modal logic is a variant of modal logic that deviates from the basic principles of normal modal logics. Normal modal logics adhere to the distributivity axiom ( ( p → q ) → ( p → q ) {\displaystyle \Box (p\to q)\to (\Box p\to \Box q)} ) and the necessitation principle which states that "a tautology must be necessarily true ...
