Bacon’s classification of our prejudices as Idols is a critical attempt to separate, in what passes for knowledge, the subjective, which has become traditional, from the real. Logic, religion, and poetry have had a bad effect on science, as is especially shown in the theatrical character of philosophy. (b) Having dispossessed ourselves of our prejudices or Idols, we are ready to proceed to a positive construction of a scientific method of work. By what, in general, ought science to be guided? By induction and experience. Bacon suggests the following steps for the science of the future:―― (1) There must be an exhaustive collection of particular instances. (2) There must then be an analysis and comparison of these instances, for to Bacon induction was not a mere enumeration of single instances. Negative instances, and instances of difference of degree, must be taken into account. Hasty generalizations must be avoided, and we must ascend gradually from the particular to the general. (3) The simple “form” of the phenomenon must be discovered. Of the four causes of Aristotle, Bacon emphasizes the “formal.” By “form” Bacon means the nature that is always present when the phenomenon is present, absent when the phenomenon is absent, and increases or decreases with the phenomenon. The “form” is the abiding essence of the phenomenon. =The English Natural Science Movement.= The natural science movement in England thus received at the start the impression of the sober Anglo-Saxon mind. Through its entire history English philosophy differed from that of the Continent. Here at the outset the Englishman is skeptical, not only of scholastic deductions from dogma, but also of deductions of all kinds.[17] He prefers the slow road of patient empirical discovery. Even pure contemplative knowledge and the deductions of mathematics have little charm for him. To be sure, induction even in the hands of an Englishman demands by its nature the establishment of a general principle, but Bacon would have refused to use such a deduction to establish a new truth in the way that Galileo used his mathematical hypotheses. According to Bacon, an hypothesis is true only so far as it has already received the indispensable sanction of experience.
