In the context of contemporary analytic philosophy, some metaphysicians adopt a "scientific" approach to their discipline, modeling their methodology on the physical sciences.1

The Scientific Approach to Metaphysics

Under this conception, metaphysicians treat their field as an inquiry that mirrors scientific investigation. The process involves two primary components:

Data Collection: Metaphysicians identify relevant data—often derived from general knowledge or scientific findings—that pertain to their specific questions.1
Theory Construction: They attempt to build theories that account for this data. When evaluating competing theories, they apply constraints similar to those used in science, such as the principle of parsimony (e.g., not multiplying entities beyond necessity).1

Challenges and Criticisms

While this approach is common among late 20th- and early 21st-century analytic philosophers, it faces significant criticism regarding its success. A primary objection is the lack of consensus among metaphysicians. Critics argue that if the scientific method were truly a reliable source of metaphysical knowledge, one would expect a degree of convergence in belief similar to that found among physical scientists.1

Furthermore, some philosophers, such as those associated with naturalism, argue that all knowledge of the universe falls within the scope of scientific investigation, often viewing traditional metaphysical speculation with skepticism.23
