Material Nonimplication

Material nonimplication or abjunction (latin ab = "from", junctio =–"joining") is the negation of material implication. That is to say that for any two propositions P and Q, the material nonimplication from P to Q is true if and only if P does not imply Q.

It may be written using logical notation as:

p⊅q
Lpq
p↛q

Famous quotes containing the word material:

    The only happy talkers are dandies who extract pleasure from the very perishability of their material and who would not be able to tolerate the isolation of all other forms of composition; for most good talkers, when they have run down, are miserable; they know that they have betrayed themselves, that they have taken material which should have a life of its own, to dispense it in noises upon the air.
    Cyril Connolly (1903–1974)
