Even texts that were written in and for themselves are closely linked to the activity of teaching, and their literary genre reflects the methods of the schools. One of the exercises esteemed in the schools consists of discussing, either dialectically, that is, in the form of questions and answers, or rhetorically, that is, in a continuous discourse, what were called "theses," that is, theoretical positions presented in the form of questions: Is death an evil? Is the wise man ever angry? This provides both training in the mastery of the spoken word and a properly philosophical exercise. The largest portion of the philosophical works of antiquity, for example those of Cicero, Plutarch, Seneca, Plotinus, and more generally those classified by the moderns as belonging to what they called the genre of diatribe, correspond to this exercise. They discuss a specific question, which is posed at the outset of the work and which normally requires a yes or no answer. In these works, the course of thought consists in going back to general principles that have been accepted in the school and arc capable of resolving the problem in question.
This search to find principles to solve a given problem thus encloses thought within narrowly defined limits. Different works written by the same author and guided according to this "zetctic" method, "one that seeks," will not necessarily be coherent on all points because the details of the argument in each work will be a function of the question asked .
Another school exercise is the reading and exegesis of the authoritative texts of each school. Many literary works, particularly the long commentaries from the end of antiquity, are the result of this exercise. More generally, a large number of the philosophical works from that time utilize a mode of exegetical thinking. Most of the time, discussing a "thesis" consists in discussing not the problem in itself but the meaning that one should give to Plato's or Aristotle's statements concerning this problem. Once this convention has been taken into account, one docs in fact discuss the question in some depth, but this is done by skillfully giving Platonic or Aristotelian statements the meanings that support the very solution one wishes to give to the problem under consideration. Any possible meaning is true provided it coheres with the t ruth one believes one has discovered in the text.

fundamental dogmas. It is precisely the third philosophical literary genre, the systematic treatise, that proposes a rational ordering of the whole of doctrine, which sometimes is presented, as in the case of Proclus, as a more geometrico, that is, according to the model of Euclid's Elements. In this case one no longer returns to the principles necessary to resolve a specific question but sets down the principles directly and deduces their consequences. These works are, so to speak, "more written" than the others. They often comprise a long sequence of books and are marked by a vast, overarching design. But, like the Summae theologicae of the Middle-Ages that they prefigure, these works must themselves also be understood from the perspective of dialectical and exegetical scholarly exercises.
Unlike their modem counterparts, none of these philosophical productions, even the systematic works, is addressed to everyone, to a general audience, but they are intended first of all for the group formed by the members of the school; often they echo problems raised by the oral teaching. Only works of propaganda are addressed to a wider audience.
Moreover, while he writes the philosopher often extends his activity as spiritual director that he exercises in his school. In such cases the work may be addressed to a particular disciple who needs encouragement or who finds himself in a special difficulty. Or else the work may be adapted to the spiritual level of the addressees. Not all the details of the system can be explained to beginners; many details can be revealed only to those further along the path.
