This study examines the history of a fundamental problem in Aristotelian cognitive psychology, i.e. the nature and function of the mechanisms that provide the human mind with data concerning physical reality.Chapter I traces the Classical and Arabic prehistory of the Medieval doctrine of intelligible species. Scholastic discussions on formal mediation in intellective cognition were constrained in essential ways by Thomas. Chapter II analyzes his views on mental representation in the context of the reception of Peripatetic psychology in the West. The following chapters (III-V) examine the controversies about the necessity of intelligible species, from Aquinas' death to the 15th century. Another volume is planned, devoted to Renaissance discussions, developments of later Scholasticism, and the elimination of the intelligible species in modern non-Aristotelian philosophy.

Medieval discussions of mental representation were constrained in essential ways by Thomas Aquinas' doctrine of intelligible species. Aquinas' view of a formal mediation of sensible reality in intellectual knowledge was not universally accepted. In particular, after his death, a long series of controversies developed about the necessity of intelligible species. (These were analyzed in the first volume of this study.) The first part of this book deals with Renaissance controversies, discussing Peripatetics, Neoplatonics, and a group of relatively independent authors. In the second part, developments of late Scholasticism, and the elimination of the intelligible species in modern non-Aristotelian philosophy are scrutinized. Particular attention is paid to the possible roots of the seventeenth-century theories of ideas in traditional philosophy.

In 1503, Nifo published De intellectu, the major work of his early career, touching on questions of philosophical psychology. Based on a detailed assessment of the views of his predecessors, Nifo in this work presented an analysis of the main issues of Peripatetic noetics, namely origin and immortality of the intellect or rational soul, its relation to the body, its unity and parts, the speculative intellect, and intellectual beatitude. Here the 1554 edition is reproduced. The Introduction is followed by an extensive analytical summary of the contents of the work. The Appendix contains a chronology of Nifo’s life and works, and a full index of the chapters of De intellectu.

Brill authors Leen Spruit and Pina Totaro discovered the original manuscript of Spinoza's "Ethica" in the Vatican library. This spectacular discovery attracted a lot of media attention.The Vatican codex, which contains the complete text of Spinoza’s Ethics, is the only surviving manuscript of this work and constitutes a document of great importance. On 23 September 1677, it was handed over to the Roman Holy Office by Spinoza’s former friend Niels Stensen who had converted to Catholicism in 1667. Thus, it predates the publication of the Opera Posthuma, which is dated 1677, but which did not in fact appear until the first months of 1678. Recent research and fresh documentation allow us to determine the several stages of the manuscript’s life before it reached Rome, where it was kept in the Archive of the Holy Office, and subsequently, transferred to the Vatican Apostolic Library, in 1922.
