I wrote The Metaphysics of Science as a follow-up and conclusion to an issue raised in Scientific Progress, viz., what is the nature of modern science.
My ‘simplistic’ leanings led me to a conception of modern science according to which the core of modern science consists of three particular principles, physically interpreted. These are i) the principle of the uniformity of nature; ii) the principle of substance, and iii) the principle of causality.
