The one thing needed to achieve scientific progress and it is essential to make an effort at gaining this quite simple insight into it is the recognition of the logical principle that negation is equally positive, or that what is self contradictory does not resolve itself into a nullity, into abstract nothingness, but essentially only into the negation of its particular content; or that such a negation is not just negation, but is the negation of the determined fact which is resolved, and is therefore determinate negation; that in the result there is therefore contained in essence that from which the result derives a tautology indeed, since the result would otherwise be something immediate and not a result.
