12253 If tropes are in space and time, in what sense are they abstract? [Oderberg]

12256 We need to distinguish the essential from the non-essential powers [Oderberg]

12252 Empiricists gave up 'substance', as unknowable substratum, or reducible to a bundle [Oderberg]

12234 Realism about possible worlds is circular, since it needs a criterion of 'possible' [Oderberg]
18746 Possible worlds models contain sets of possible worlds; this is a large metaphysical commitment [Horsten/Pettigrew]
18750 Using possible worlds for knowledge and morality may be a step too far [Horsten/Pettigrew]
10. Modality / E. Possible worlds / 3. Transworld Objects / a. Transworld identity
12235 Necessity of identity seems trivial, because it leaves out the real essence [Oderberg]
