Apodicticity

Apodictic (Greek apodeiktikos, conclusive ') stands for

• Actually: irrefutable claims determined by striking proof strength
• Generally, however, rather pejoratively: not refutable, necessarily correct, without further explanation immediately certain, brooking no contradiction, no other opinion are leaving

A apodictic statement is a statement whose opposite can not possibly be true, because the evidence base is a generally recognized incontrovertible truth. A distinction is made between mathematical, logical and philosophical apodictic statements. In today's parlance often means " no contradiction tolerating " meant.

Studies of statements of this kind fall within the scope of modal logic.

The doctrine of the apodictic statements is called Apodiktik, also theory of evidence (philosophy)

Apodictic law as contained in the Decalogue, for example, demands of man a certain behavior ( Thou shalt / thou shalt not ).
