Mario Bunge's Foundations of Physics: A Critical Review
Mario Bunge was a prominent philosopher of science who wrote extensively on the foundations of physics. His book Foundations of Physics, published in 1967, is a systematic and rigorous analysis of some of the key concepts and theories of physics, such as space, time, motion, causality, fields, quantum mechanics, and relativity. Bunge aimed to clarify the logical structure and physical meaning of these notions, as well as to expose their philosophical implications and presuppositions. He also criticized some of the prevailing philosophical views that he considered to be misleading or obstructive for the understanding and progress of physics.
In this article, we will review some of the main ideas and arguments of Bunge's book, as well as some of the criticisms and challenges that it has faced over the years. We will also discuss its relevance and significance for contemporary physics and philosophy of science.
Bunge's Approach to the Foundations of Physics
Bunge's approach to the foundations of physics can be characterized by several features:
He adopted a realist stance, according to which physical theories aim to describe and explain objective aspects of reality that exist independently of our observations and measurements. He rejected instrumentalism, conventionalism, and other forms of anti-realism that deny or downplay the ontological commitment of physics.
He advocated a systematic and axiomatic method for formulating physical theories, in which the basic concepts, principles, and laws are explicitly defined and logically derived from a set of postulates. He opposed the use of vague or ambiguous terms, ad hoc hypotheses, or unjustified assumptions that may introduce inconsistencies or contradictions in the theories.
He emphasized the unity and coherence of physics as a network of interrelated theories that share common concepts and methods. He opposed the fragmentation or isolation of different branches or domains of physics that may lead to incomparability or incompatibility among them.
He recognized the historical and sociological dimensions of physics as a human activity that is influenced by various factors such as empirical evidence, logical reasoning, aesthetic criteria, ethical values, social interests, etc. He acknowledged the role of creativity and imagination in the discovery and invention of new theories, as well as the role of criticism and revision in their evaluation and improvement.
He explored the philosophical implications and presuppositions of physics for various topics such as ontology, epistemology, logic, metaphysics, ethics, etc. He also examined the relations between physics and other disciplines such as mathematics, biology, psychology, etc.
Bunge's Analysis of Some Key Concepts and Theories of Physics
Bunge's book covers three major areas of physics: classical mechanics, classical field theories (including electromagnetism and general relativity), and quantum mechanics. In each area, he analyzes some of the fundamental concepts and theories that are essential for understanding modern physics. Some examples are:
In classical mechanics, he discusses the notions of space, time, motion, mass, force, energy, momentum, etc., as well as Newton's laws of motion and conservation laws. He also introduces his own theory of causality as a relation between events that involves both necessity and contingency.
In classical field theories, he discusses the notions of field, charge, current, potential, etc., as well as Maxwell's equations and Einstein's field equations. He also introduces his own theory of fields as physical entities that have both properties (such as intensity) and relations (such as divergence).
In quantum mechanics, he discusses the notions of wave function, state vector, operator, observable,
measurement,
etc., as well as SchrÃdinger's equation
and Heisenberg's uncertainty principle.
He also introduces his own interpretation
of quantum mechanics
as a statistical theory
that describes
the probabilities
of possible outcomes
of measurements
on physical systems.
