a posteriori Discourses


Reasoned thought as the source of truth

Principal Metaphors

  • Knowledge is … demonstrable truths
  • Knowing is … evidence-based awareness
  • Learner is … an inquirer
  • Learning is … deriving truth from evidence
  • Teaching is … formatting experiences




The phrase a posteriori is Latin for “from the later” (and it is typically contrasted with a priori, Latin for “from the earlier”). The term is used both to refer to truth claims that are based on replicable evidence (e.g., via observation, experimentation, empirical demonstration) and to categorize discourses that privilege observation over argument.


The phrase a posteriori is certainly useful for purposes of description and categorization of those discourses that assume separations of reasoned conclusion and observed evidence. As we aim to illustrate through this site, however, issues arise when it is coupled with a priori to generate a continuum that is imagined to span all claims to truth and all discourses on knowledge and learning.
