Berkeleyan Idealism (BI) is the view that objects do not exist independently of our experience and perception. At first glance, this theory seems incompatible with science because it denies the existence of objective material reality, which is the focus of scientific investigation. This paper examines whether Berkeleyan Idealism is compatible with science by considering several common scientific platitudes, including the empirical basis of science, its aim of objective knowledge, the possibility of perceptual error, and the search for causal explanations. It argues that BI is compatible with the empirical foundations of science because all knowledge is grounded in perception and sense experience. The paper then addresses objections that BI is not compatible with science. It argues that objectivity depends on the formation of knowledge, that perceptual errors can be explained through differences in the quality of perception, and that causal explanations may be understood through repeated perception. The paper concludes that Berkeleyan Idealism remains compatible with contemporary science.
