In Seminar VII: The Ethics of Psychoanalysis 1959-1960, Lacan says the following about reading Aristotle:
There are no doubt a number of difficulties to be found at the level of the text, and it's digressions and in the order of his arguments. But skip over the passages that seem too complicated or require an addition with good notes that refers you to what is sometimes essential to know about his logic, in order to understand the problems that he raises. Above all, don't overburden yourself by trying to grasp everything paragraph by paragraph. Try instead to read him from beginning to end, and he will certainly be rewarded. (p. 22)
I think Lacan's advice on how to read Aristotle is the same advice I give students when it comes to reading Lacan.
