Single Idea 5566

[filed under theme 10. Modality / B. Possibility / 1. Possibility ]

Full Idea

Whether the field of possibility is greater than the field that contains everything actual, and whether the latter is in turn greater than the set of that which is necessary, are proper questions.

Gist of Idea

Is the possible greater than the actual, and the actual greater than the necessary?

Source

Immanuel Kant (Critique of Pure Reason [1781], B282/A230)

A Reaction

A good overview. Is the actual necessary (i.e. is only the actual possible?)? Why is the non-actual possible? What would a theory look like which explains why the necessary is necessary, the actual actual, and the possible possible? A religion?
