The Source(s) of Necessity

Though virtually all philosophers agree that a sentence like ‘Every bachelor is a bachelor’ expresses a logical truth, there is some disagreement as to whether ‘Every bachelor is unmarried’ does. One way of addressing the question as to whether ‘Every bachelor is unmarried’ expresses a logical truth is to ask whether the source of the necessity of ‘Every bachelor is a bachelor’ is the same as the source of the necessity of ‘Every bachelor is unmarried’. Assuming the framework of the theory of structured propositions, the question of whether the propositions expressed by these two sentences have their necessity in the same source is addressed. The view that the source of necessity is the same in the two cases is rejected, and an alternative view is sketched.
