Occasion. The fourth of the twenty-five Public Disputations printed in the Opera and in Nichols's English, and the only one in which Arminius is himself the respondent: these are the theses he defended for his doctorate in divinity. The Leiden quarto is dated 1603 (shelfmark 236 A 6: 72). It is not among the seven also printed in the 1615 Syntagma. By far the longest of the twenty-five, it runs to ninety-three theses.
The doctrinal move. Theses I–V establish that a nature is rightly ascribed to God and how it can be known: not a priori, but either by vision or, for us, mediately through his works and word, by the two modes of affirmation and of negation or removal (IV). Thesis V then names the only two perfections the mind can conceive, Essence and Life, and these frame what follows; two problems on their analogy come next. From VI the disputation treats the nature of God under an order of "moments": first his Essence (VI–XXIV), whose pre-eminent modes (simplicity, infinity, eternity, immensity, omnipresence, impassibility, immutability) belong to God alone, and whose general affections are unity and goodness; then his Life (XXV–XXIX), the act flowing from the Essence, exercised in three faculties. The Understanding (XXX–XLVI) knows all things by one simple and infinite intuition, and the section distinguishes theoretical from practical knowledge, vision from simple intelligence, and names the Schoolmen's natural, free and middle knowledge. The Will (XLVII–LXXVII) is ordered first to the Chief Good and then to other goods; the theses set out its freedom, its modes, and the affections and virtues analogous to it, among them love, hatred, goodness, mercy, anger and righteousness. The Power or Capability of God (LXXVIII–LXXXVI) and his Perfection, Blessedness and Glory (LXXXVII–XCIII) close the account, and a prayer ends the disputation.
