Interpreting phenomena as sums of parts

Principal Metaphors

  • Knowledge is … both parts to assemble and assemblages of parts
  • Knowing is … acting on assembled truths
  • Learner is … an assembler
  • Learning is … putting together
  • Teaching is … breaking things down




Reductionism is a descriptive notion that can be applied to any discourse that embraces the premise that an object, agent, event, or any other type of phenomenon can be fully understood in terms of either simpler phenomena or as the sum of its parts. Types of Reductionism include:
  • Methodological Reductionism – any approach to study that is oriented by an intention to provide explanations for phenomena in terms of smaller or simpler phenomena.
  • Ontological Reductionism – any belief system in which the entirety of reality is seen to consist of different combination of a few specified parts or elements (such as, e.g., earth, fire, air, and water).
  • Theory Reductionism – an assertion that new, more expansive and/or powerful theories operate by reducing previous theories to simpler or more basic terms.


The major (and condemning) commentaries on reductionism are associated with Emergent Complexity Discourses and Ecological Discourses, which flatly assert the underlying premise of Reductionism is false.

Status as a Theory of Learning

While usually applied specifically to discussions of knowledge (rather than learning), the assumptions of Reductionism and its subdiscourses are evident in virtually all Correspondence Discourses.

Status as a Theory of Teaching

Reductionism is not a theory of teaching, but its core premise is pervasively present in modern schooling – and especially evident in Directive Pedagogies.

Status as a Scientific Theory

The notion that a phenomenon might be understood by reducing it to simpler phenomena was foundational to modern science, and so Reductionism is integral to both Empiricism and Rationalism. However, the realization that some phenomena transcend their parts has exposed Reductionism as an over-applied assumption rather than a defensible principle of scientific study. It is relevant and appropriate to many phenomena, but it is of limited relevance and use in the study of such complex phenomena as learning.
