Abstract
This text concentrates on the investigation of relations of two books of Alfred North Whitehead: Process and Reality and Function of Reason, both being published in the same year 1929. Author of the text first exhibit Whitehead’s conception of method of speculative philosophy as it is presented on the initial pages of Process and Reality.
He points out at Whitehead’s rejection of mathematical axiomatic method and position of rigid empiricism as appropriate methods of construction of philosophical scheme and shows Whitehead’s own philosophical method: method of descriptive generalization. It is shown that Whitehead does not presents in Process and Reality the process of imaginative construction of his philosophy.
One phase of Whitehead’s method of descriptive generalization is therefore missing in Process and Reality. It is argued that this missing phase of descriptive generalization can be found in Function of Reason.
