The Unreliability of Worldviews and Their Implications for Enterprise Architecture

1. The "Unreliability" of Worldviews

The term "worldview" has two layers: observation (the act of watching) and conception (the ideas formed from observation). Historically, Aristotle’s purpose‑driven worldview dominated for two millennia, aligning well with religious thought, but later observations by Copernicus, Tycho, Kepler, Galileo, and ultimately Newton overturned it, introducing a mechanistic, purpose‑free universe.

Newton’s mechanics treated space and time as absolute, yet could not explain action at a distance, prompting Einstein to replace them with a relativistic view where space‑time is curved by mass, resolving the “instantaneous” gravity problem.

Einstein’s theory further reshaped concepts, showing planetary orbits as straight‑line motion in curved space, analogous to running on a bent track.

Biology followed a similar pattern: Darwin’s evolution, grounded in extensive data, altered the conception of life, and quantum theory later introduced probabilistic, observer‑dependent notions such as superposition and many‑worlds.

Each new worldview renders previous ones partially obsolete, yet both instrumentalism (focus on predictive utility) and realism (demand for correspondence with reality) coexist, as illustrated by the continued use of Newtonian physics for practical engineering despite its theoretical limitations.

2. Applying the Concept to Enterprise Architecture

Enterprise architecture itself is a worldview: it observes internal structures and their relationships to the environment, then formulates guiding principles. It blends purpose‑driven (teleological) thinking with mechanistic elements, but often leans toward realism—emphasizing concrete implementation and accurate representation of current or target states.

Current architectural theories tend toward “purpose‑plus‑realism,” lacking the objectivity of a fully mechanistic approach. To mature, architecture should adopt more mechanistic, standardized components (instrumentalism) while reserving realism for necessary customizations, thereby reducing subjective design and improving reusability across enterprises.
