 One would interpret Bob's "wisdoms" as various pieces of Bob's wisdom (that is, don't run with scissors, defer to those with greater knowledge), "deceits" as a series of instances of deceitful behaviour (lied on income tax, dated my wife), and the different "idlenesses" of the worker as plural distinct manifestations of the mass concept of idleness (or as different types of idleness, "bone lazy" versus "no work to do").The pair "specie" and "species" both come from a Latin word meaning "kind", but they do not form a singular-plural pair.In Latin, "specie" is the ablative singular form, while "species" is the nominative form, which happens to be the same in both singular and plural.
