Temporality and Modality

In common parlance, 'possibility' is usually attributed to an as yet undetermined future.  Likewise, if one such possibility is actualized, it occurs in the present.  And, if there is anything that is absolutely unchangeable, it is what has already occurred, i. e. the past.  Thus, 'necessity', too, has a practical temporal significance, and is systematically related to 'actuality' and 'possibility' in that context.  Accordingly, to abstract the three from this temporal coordination is to eliminate that systematic interaction.  But that is what Modal Logicians do when they cast them as Modal operators, resulting in inadequacies that have been previously discussed.  Furthermore, and perhaps more seriously, treating the future as inevitable can be resigned submission, and treating the past as still open can be delusional.  Accordingly, a concept of Modal Logic as anything other than Methodological, e. g. as Ontological, is perhaps a symptom of a Psychological disorder.
