The categories of metaphysical possibility and metaphysical possibility have been criticized as unscientific and unsuitable for serious theorizing. I will develop an alternative view on which they are limiting cases of a family of objective modalities many members of which are studied in natural science, and discuss the modal aspect of applied mathematics. Some consequences for the logic of metaphysical modality will be discussed.
