Hornstein entered the Jesuit order in 1744 and later held the professorship of philosophy and moral theology at Dillingen and Freiburg. Between 1768 and 1770 he served as Amanuensis Germaniae at the seat of the General of the Jeusites in Rome, before becoming a Scholasticus at Ellwangen in 1773.

The illustration comprises nine curious mnemonic plates and is divided into eight chapters, each with the following titles: Propylaeum sapientiae; Idearum idea; Terminorum usus; Arbor systematica; Iudicium; Suppasitionis officina; Pugna contradicitionis; Organum Aristotelicum; Inventio et criterium veritatis.

The beautiful binding could have been realised in the bookbinder's workshop at Ettal Abbey.
