soundness englannista suomeksi
The state or quality of being sound.
The result or product of being sound.
The property of a logical theory that whenever a wff is a theorem then it must also be valid. Symbolically, letting ''T'' represent a theory within logic ''L'', this can be represented as the property that whenever T \vdash \phi is true, then T \vDash \phi must also be true, for any wff ''φ'' of logic ''L''.
