Single Idea 14786

[catalogued under 10. Modality / B. Possibility / 1. Possibility]

Full Idea

Many say everything is logically possible which involves no contradiction. In this sense two contradictory propositions may be severally possible. In the substantive sense, the contradictory of a possible proposition is impossible (if we were omniscient).

Gist of Idea

Some logical possibility concerns single propositions, but there is also compatibility between propositions
