Abstract
In this book the analysis of the relationship between Whewell and Mill is extended from the theme of induction, the topic the author starts with, to the comparison between the two projects of an overall reform of knowledge. These programmes announce themselves to the general public as proclamations of war for or against the academic, political and religious establishment; however, when viewed from the inside, they more or less consciously share very similar objectives. This applies both to the scientific method and to ethics and politics.
