Similarly Alan R . Anderson ( 1959 ) shows how to define O in terms of the alethic operator \ Box and a deontic constant ( i . e . 0-ary modal operator ) s standing for some sanction ( i . e . bad thing, prohibition, etc . ) : OA \ equiv \ Box ( \ lnot A \ to s ).

Logical possibility is a form of " alethic " possibility; ( 4 ) makes a claim about whether it is possible ( i . e ., logically speaking ) that a mathematical truth to have been false, but ( 3 ) only makes a claim about whether it is possible, for all Jones knows, ( i . e ., speaking of certitude ) that the mathematical claim is specifically either true or false, and so again Jones does not contradict himself.

Epistemic possibility is often contrasted with subjunctive possibility ( or "'alethic possibility "'), and although epistemic and subjunctive possibilities are often expressed using the same modal terms ( such as " possibly ", " could be ", " must be " ) or similar modal terms that are sometimes confused ( such as " may be " and " might be " ), statements that are qualified in terms of epistemic possibility and statements that are qualified in terms of subjunctive possibility have importantly different meanings.
