that is to be found in human consciousness; it will be _a complete recapitulation, as it were, a reflection, of the world in abstract concepts_, which is only possible by the union of the essentially identical in _one_ concept and the relegation of the different to another. This task was already prescribed to philosophy by Bacon of Verulam when he said: _ea demum vera est philosophia, quae mundi ipsius voces fidelissime reddit, et veluti dictante mundo conscripta est, et nihil aliud est, quam ejusdem_ SIMULACRUM ET REFLECTIO, _neque addit quidquam de proprio, sed tantum iterat et resonat_ (De Augm. Scient., L. 2, c. 13). But we take this in a wider sense than Bacon could then conceive. The agreement which all the sides and parts of the world have with each other, just because they belong to a whole, must also be found in this abstract copy of it. Therefore the judgments in this sum-total could to a certain extent be deduced from each other, and indeed always reciprocally so deduced. Yet to make the first judgment possible, they must all be present, and thus implied as prior to it in the knowledge of the world in the concrete, especially as all direct proof is more certain than indirect proof; their harmony with each other by virtue of which they come together into the unity of _one_ thought, and which arises from the harmony and unity of the world of perception itself, which is their common ground of knowledge, is not therefore to be made use of to establish them, as that which is prior to them, but is only added as a confirmation of their truth. This problem itself can only become quite clear in being solved.(23)
