 The general attitude, present throughout Łukasiewicz’s treatment, is that Aristotle’s work is of sufficient precision and stature to warrant and withstand exposition using the most rigorous modern logical methods and concepts. In other words, the development of modern logic, while it may highlight lacunae and deficits of Aristotle’s logic, in fact brings out its merits, innovations and genius more clearly than previous traditional or philological studies. Łukasiewicz’s attitude has prevailed and is now pervasive among those studying Aristotle’s logic, whether or not they agree with his specific interpretative principles.
