 Notice that both conjuncts of the modal transfer principle must be satisfied for it to apply. That is, for the modal transfer principle to apply to some y, it must be the case that both (i) y follows necessarily from x and (ii) x exists necessarily. Hence, if God exists necessarily and if the existence of Bruce Springsteen follows necessarily from God’s existence, then Springsteen exists necessarily too. Whatever differences there may be between a thing that exists necessarily in virtue of its own nature and a thing that exists necessarily in virtue of following from something else that exists necessarily, that distinction is wholly internal to necessity. Differences between external and internal sources of necessity, a difference to which Spinoza sometimes draws attention (Ip33s), does not entail differences in type of necessity or even strength of necessity, and Spinoza nowhere says that it does.
