In contrast with this point of view, Bacon eloquently proclaimed the superiority of discovery of new facts and truths to demonstration of the old. Now there is only one road to discovery, and that is penetrating inquiry into the secrets of nature. Scientific principles and laws do not lie on the surface of nature. They are hidden, and must be wrested from nature by an active and elaborate technique of inquiry. Neither logical reasoning nor the passive accumulation of any number of observations--which the ancients called experience--suffices to lay hold of them. Active experimentation must force the apparent facts of nature into forms different to those in which they familiarly present themselves; and thus make them tell the truth about themselves, as torture may compel an unwilling witness to reveal what he has been concealing. Pure reasoning as a means of arriving at truth is like the spider who spins a web out of himself. The web is orderly and elaborate, but it is only a trap. The passive accumulation of experiences--the traditional empirical method--is like the ant who busily runs about and collects and piles up heaps of raw materials. True method, that which Bacon would usher in, is comparable to the operations of the bee who, like the ant, collects material from the external world, but unlike that industrious creature attacks and modifies the collected stuff in order to make it yield its hidden treasure. Along with this contrast between subjugation of nature and subjection of other minds and the elevation of a method of discovery above a method of demonstration, went Bacon's sense of progress as the aim and test of genuine knowledge. According to his criticisms, the classic logic, even in its Aristotelian form, inevitably played into the hands of inert conservatism. For in accustoming the mind to think of truth as already known, it habituated men to fall back on the intellectual attainments of the past, and to accept them without critical scrutiny. Not merely the medieval but the renaissance mind tended to look back to antiquity as a Golden Age of Knowledge, the former relying upon sacred scriptures, the latter upon secular literatures. And while this attitude could not fairly be charged up against the classic logic, yet Bacon felt, and with justice, that any logic which identified the technique of knowing with demonstration of truths already possessed by the mind, blunts the spirit of investigation and confines the mind within the circle of traditional learning.
