ISBN: 978-3-88405-595-3

Price: €9.80 (including 19 % tax)

Such is also the case for the deontic modalities ‘it is permitted that’ (often symbolised as ‘P’) and ‘it is obligatory that’ (often symbolised as ‘O’). These modalities are dual in the sense that ‘non-P-non’ corresponds to ‘O’: if it is obligatory that p, then it is not permitted that non-p. (Consequently, ‘non-O-non’ corresponds to ‘P’). In formal contexts it is customary to take the strong ‘O’ modality as basic and to treat the weak ‘P’ as an abbreviation; sometimes ‘F’ (‘it is forbidden that’) is used as an abbreviation for ‘Onon’ (equivalently, for ‘non-P’).
