    It is not the case that The inference from '∃x Human(x)' to 'humanity exists' is valid only given a prior substantive metaphysical assumption that predicates denote universals.

    ?Set your confidence on the premises below to see your aggregate.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.First-order quantification can be interpreted purely nominally: '∃x Human(x)' means 'some concrete particular is human' without universals.
      ?

      Think about whether this reason is strong or weak

    • 2.'Humanity exists' may simply report the instantiation of a pattern across particulars, not require commitment to abstract entities.
      ?

      Think about whether this reason is strong or weak

    • 3.The inference's validity depends on how 'humanity exists' is parsed, not necessarily on prior metaphysical assumptions about universals.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.The existential quantifier '∃x' ranges over objects satisfying predicates, requiring those predicates to have determinate extension.
      ?

      Think about whether this reason is strong or weak

    • 2.Without universals, predicates become merely linguistic conventions, making '∃x Human(x)' true only of word-usage, not reality.
      ?

      Think about whether this reason is strong or weak

    • 3.Inferring 'humanity exists' from '∃x Human(x)' treats humanity as an abstract object; this requires predicates to denote mind-independent universals.
      ?

      Think about whether this reason is strong or weak
