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:
“Any so-called material thing that you want is merely a symbol: you want it not for itself, but because it will content your spirit for the moment.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
