|Possibilia, philosophy: possibilia are accepted, possible objects that do not exist (in our world) actually. It is controversial whether one should discuss them at all, since their properties are not so clearly defined that they can always be distinguished from one another, for example, to count them. See also possibilism, actualism, modal realism._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them. Instead, they are intended to give a short introduction to the contributions below. – Lexicon of Arguments. |
