Defeasible Arguments
An argument is defeasible when additional information (such as new counterreasons) can have the effect that it no longer justifies its conclusion. The term "defeasibility" goes back to the legal theorist H.L.A. Hart, although he focused on concepts instead of arguments. Stephen Toulmin's influential argument model includes the possibility of counterreasons that are characteristic of defeasible arguments, but he did not discuss the evaluation of defeasible arguments. Defeasible arguments give rise to defeasible reasoning.

Famous quotes containing the word arguments:
“Through Plato Aristotle came to believe in God, but Plato never attempted to prove His reality. Aristotle had to do so. Plato contemplated Him; Aristotle produced arguments to demonstrate Him. Plato never defined Him, but Aristotle thought God through logically and concluded with entire satisfaction to himself that He was the Unmoved Mover.”
—Edith Hamilton (1867–1963)
