  Not all permanent properties are necessary. The property of having been conceived in Provo is a permanent property of Susan but contingent, as her mother could have been elsewhere when Susan was conceived. In response to the modal version of our second problem, a substance theorist should claim that the constituents of singular propositions are independent of their contingent properties but involve their necessary properties. Where F is a necessary property of o and G a contingent, temporary property of o, the singular proposition [o is F] is true at evey index while the proposition [o is G] is true at some times and worlds and false at others. o is thus independent of its contingent but not necessary properties. The substance theorist can insist, then that the object constituent of (10) is not a property-less bare particular, but instead an entity clad in its necessary properties.
