General Introduction

Abstract

This chapter begins with a commitment to scientific realism and reasons for accepting the existence of an objective quantum realm. The notion of causality in the context of physical theories is discussed together with a (defined) Principle of Causality. The Causal Theory of Quantum Mechanics is then introduced together with a list of its advantages and another of its alleged flaws which will be addressed in later chapters. Criteria for the appraisal of rival scientific theories are presented which will be used in assessing the merits of both the Causal Theory of Quantum Mechanics and Orthodox Quantum Theory. The distinction between conceptual and theoretical problems as found in scientific theories is made explicit and examples are provided from the history of physical science.
