In the "Parasceve" he says:--"If all the wits of all the ages had met or shall hereafter meet together; if the whole human race had applied or shall hereafter apply themselves to philosophy, and the whole earth had been or shall be nothing but academies and colleges and schools of learned men; still without a natural and experimental history such as I am going to prescribe, no progress worthy of the human race could have been made or can be made in philosophy and the sciences. Whereas on the other hand let such a history be once provided and well set forth and let there be added to it such auxiliary and light-giving experiments as in the very course of interpretation will present themselves or will have to be found out; and the investigation of nature and of all sciences will be the work of a few years. This therefore must be done or the business given up." To carry out this work an army of workers was required. In the preparation of each history some were to make a rough and general collection of facts. Their work was to be handed over to others who would arrange the facts in order for reference. This accomplished, others would examine to get rid of superfluities. Then would be brought in those who would re-arrange that which was left and the history would be completed. From Chapter CIII. it is clear that Bacon contemplated that eventually all the experiments of all the arts, collected and digested, _should be brought within one man's knowledge and judgment_. This man, having a supreme view of the whole range of subjects, would transfer experiments of one art to another and so lead "to the discovery of many new things of service to the life and state of man." Nearly three hundred years have passed since Bacon propounded his scheme. The arts and sciences have been greatly advanced. They might have proceeded more rapidly had the histories been prepared, but since his time there has arisen no man who has taken "all knowledge to be his province"--no man who could occupy the position Bacon contemplated. The method by which the induction was to be followed is described in Chapter CV. There must be an analysis of nature by proper rejections and exclusions, and then, after a sufficient number of negatives, a conclusion should be arrived at from the affirmative instances. "It is in this induction," Bacon adds, "that our chief hope lies." Bacon's new organ has never been constructed, and all wits and understandings have not yet been placed on a level.
