attempts to combine positivism with a version of a-priorism. Another theory of truth which is related to a-priorism is the concept-containment theory of truth. The concept-containment theory of truth is the view that a proposition is true if and only if the concept of the predicate of the proposition is "contained in" the concept of the subject. For example, the proposition that bachelors are unmarried men is true, on this view, because the concept of the predicate (unmarried men) is contained in the concept of the subject (bachelor). A contemporary reading of the concept-containment theory of truth is to say that every true proposition is an analytically true proposition.

's philosophy are some of the most famous examples of such perspectivism. There are three main versions of perspectivism, and some interesting subdivisions:

Individualist perspectivism

According to individualist perspectivism (also individual perspectivism) perspectives are the points of view of particular individual persons. So, a proposition is true for a person if and only if it is accepted or believed by that person (i.e., "true for me").

Collectivist perspectivism

In collectivist perspectivism, perspectives are understood as collective (

-dependent). There are, roughly, three versions of collectivism:

Consensus

A perspective is, roughly, the broad opinions, and perhaps norms and practices, of a

of people, perhaps all having some special feature in common. So, a proposition is true (for a community C) if, and only if, there is a consensus amongst the members of C for believing it.

Power

Transcendental perspectivism

On this conception, a truth-conferring perspective is something transcendental, and outside immediate human reach. The idea is that there is a transcendental or ideal epistemic perspective and truth is, roughly, what is accepted or recognized-as-true from that ideal perspective. There are two subvarieties of

is not strictly classifiable as an epistemic theory of truth, it does bear a relationship to theories of truth that are based on concepts of inquiry and knowledge. The ideal epistemic perspective is that of "completed science", which will appear in the (temporal) "limit of scientific inquiry". A proposition is true if and only if, in the long run it will come to be accepted by a group of inquirers using scientific rational inquiry. This can also be modalized: a proposition is true if, and only if, in the long run it would come to be accepted by a group of inquirers, if they were to use scientific rational inquiry. This view is thus a modification of the consensus view. The consensus need to satisfy certain constraints in order for the accepted propositions to be true. For example, the methods used must be those of scientific inquiry (
