If events are indeed particulars then an important question concerns the conditions of identity for events.
Sometimes the unintelligibility of abstract objects is linked to their lack of clear and intelligible conditions of identity.
But it is not the abstractness of abstract objects that makes them lack clear identity conditions, since some abstract objects, like sets, have clear and intelligible conditions of identity.
The main difficulty is the trouble of keeping track of what we are talking about when it becomes crucial to know what pertains to what on account of what; in general, when the conditions of identity and distinction of the items we are talking about become variable and occasionally rather unclear.
Note that Quine thought that the relativity of eternal sentences to languages turned them problematic in a way similar to propositions, for Quine thought that the notion of language has no clear and intelligible conditions of identity, and this is what he found problematic about propositions (Quine 1969, 142).
Conditions of identity (VS/VO) were pseudo-randomly mixed within blocks, together with a "fixation" condition, consisting of the presentation of a fixation sign in the center of an otherwise blank screen.
The BLASTX search using the KEGG DB under the conditions of identity ≥70% and bit-score ≥40 led to the successful assignment of putative gene functions for 29% of the reads on average (ranging from 24 to 35%) (Supplementary Table S11 for gene abundance of each KO-assigned protein).
The terms and conditions of identity theft insurance, automatic transfer to an IRA or other services may require that you cancel each product individually.
Haysom's diagnosis was borderline personality disorder, a condition of unstable identity and impulse control.
They satisfy the criterion of phonetic similarity, but this, though a necessary condition of phonemic identity, is not a sufficient one.
