Yardsticks of Success
Truth-Seeking
- Science-Like Evaluation
- Timothy Williamson, Thomas Nagel
This framework treats philosophy as a discipline continuous with science, aiming at objective truth about reality, knowledge, and value. Success is measured by logical rigor, explanatory power, consistency with evidence, and the ability to resolve or clarify problems. Philosophical progress occurs through refinement, elimination of weaker theories, and gradual convergence toward more accurate accounts, even if certainty remains elusive.
Coherence-Building
- Reflective Equilibrium
- John Rawls
This approach sees philosophy as the construction of a stable, internally consistent system of beliefs. Using the method of reflective equilibrium, philosophers iteratively adjust general principles and specific intuitions until they align. Success is judged by how well a theory achieves coherence, balance, and resilience without contradiction, even if multiple coherent systems can coexist.
Concept-Creation
- Generative Philosophy
- Gilles Deleuze, Félix Guattari
In this view, philosophy’s primary task is not to discover truths or unify beliefs, but to create new concepts that reshape understanding. Success is measured by originality, usefulness, and the ability of ideas to open new ways of thinking or reframe existing problems. Philosophical progress is the expansion of the conceptual landscape rather than convergence on a single correct answer.
