Abstract
If it is true, as Prof. Seidel contends, that “Fichte is a philosophical genius of the first water”, so too is it true that he remains for contemporary readers one of the more inaccessible philosophical authors and that even his most important and celebrated work, the Grundlage der gesamten Wissenschaftslehre of 1794, “cries out for a commentary”. No one who has struggled to come to terms with this fabulously abstract and frequently impenetrable text is likely to disagree with this judgment, and hence the appearance of an English language commentary on it is certainly a cause for celebration.
