“Whitehead’s contributions to relativity, gravitation, and ‘unified field’ theory grew out of his preoccupations with the principles underlying our knowledge of nature. These philosophical considerations are presented chiefly in ‘An Enquiry Concerning the Principles of Natural Knowledge‘ (1919), ‘The Concept of Nature‘ (1920), and ‘The Principle of Relativity‘ (1922)” (DSB:XIV:305).
