Perspectivism and Truth

According to what is probably the most common theory of Truth, the Correspondence Theory, Truth is a relation between a Proposition and some object.  In contrast, according to the most prominent rival, the Coherence Theory, Truth is a relation among a set of Propositions.  But, neither is suitable for Perspectivism.  For, each entails an independence, from an object of cognition, of an act of cognition expressed by a relevant Proposition, while according to Perspectivism, a cognition is inherently relative to its object.  However, it does not follow that Perspectivism agrees with Subjectivism that propositions cannot be objectively evaluated.  For, as the comparison of 'The sun crosses the sky from East to West' and 'The Earth spins from West to East' shows, one proposition can be truer than another because more comprehensive, including social judgments.  So, appropriate to Perspectivism is what can be called the Comprehensiveness Theory, which entails the possibility of greater and lesser Truth.
