The paper offers a discussion of Philip Merlan's contributions (in "From Platonism to Neoplatonism, The Hague 1960, e in some papers of his, now included in his "Kleine Philosophische Schriften", Hildesheim 1976) to the understanding of Aristotle's metaphysics, with particular reference to the science of being qua being.

The paper was originally intended to serve as an introduction to the Italian translation of Kurt von Fritz's "Grundprobleme der antiken Wissenschaft, Berlin, 1971, pointing out the merits but also certain limitations of the book. (Because it appeared too critical it was not accepted by the italian publisher Il Mulino.)

The paper is a long, detailed, critical presentation of Ingemar Duering's Aristoteles. Darstellung und Interpretation seines Denkens, Heidelberg 1966, on the occasion of the publication of the Italian translation (by P.L. Donini, Milano 1976) of the same.

The treatment of Presocratic philosophy from Hegel to Zeller.

The paper is concentrated on Aristotle's "Posterior Analytics" and attempts to show that his account of the sciences is less uniform than it is usually taken to be but shows some awareness of important differences between the mathematical and the physical sciences.

In this paper I discuss the issue how far Presocratic cosmology can be regarded as scientific, giving attention to some examples of their explanations of physical phaenomena.

This is the fullest existing collection of the texts, for the moment only in Italian translation, with an introduction, notes, general presentation of the texts, various indexes (part of this material is to be found in an attached CD).

A paper on some logical procedures used by Aristotle, with comparisons with the procedures used in recent analytic philosophy.
