How To Read A Book- A Classic Guide to Intelligent Reading - Mortimer J. Adler, Charles Van Doren [133]
Plato. Other philosophers have attempted dialogues-for example, Cicero and Berkeley-but with little success. Their dialogues are Hat, dull, almost unreadable. It is a measure of the greatness of Plato that he was able to write philosophical dialogues that, for wit, charm, and profundity are the equal of any books ever produced by anyone, on any subject. Yet it may be a sign of the inappropriateness of this style of philosophizing that no one except Plato has ever been able to handle it effectively.

That Plato did so, goes without saying. All Western philosophy, Whitehead once remarked, is but "a footnote to Plato"; and the later Greeks themselves had a saying: "Everywhere I go in my head, I meet Plato coming back." Those statements, however, should not be misunderstood. Plato himself had apparently no philosophical system, no doctrine-unless it was that there is no doctrine, that we should simply keep talking.
And asking questions. For Plato, and Socrates before him, did indeed manage to raise most of the important questions that subsequent philosophers have felt it necessary to deal with.
2. THE PHn.osoPWCAL TREATISE OR EssAY: Aristotle was Plato's best pupil; he studied under him for twenty years. He is said to have also written dialogues, but none of these survives entirely. What does survive are curiously difficult essays or treatises on a number of different subjects. Aristotle was obviously a clear thinker, but the difficulty of the surviving works has led scholars to suggest that they were originally notes for lectures or books-either Aristotle's own notes, or notes taken down by a student who heard the master speak.
We may never know the truth of the matter, but in any event the Aristotelean treatise was a new style in philosophy.
The subjects covered by Aristotle in his treatises, and the various styles adopted by him in presenting his findings, also helped to establish the branches and approaches of philosophy in the succeeding centuries. There are, first of all, the so-called popular works-mostly dialogues, of which only fragments have come down to us. Then there are the documentary collections. The major one that we know about was a collection of 158 separate constitutions of Greek states. Only one of these survives, the constitution of Athens, which was recovered from a papyrus in 1890. Finally, there are the major treatises, some of which, like the Physics and Metaphysics, or the Ethics, Politics, and Poetics, are purely philosophical works, theoretical or normative; some of which, like the book On the Soul, are mixtures of philosophical theory and early scientific investiga-282 HOW TO READ A BOOK
tion; and some of which, like the biological treatises, are mainly scientific works in the field of natural history.
Immanuel Kant, although he was probably more influenced by Plato in a philosophical sense, adopted Aristotle's style of exposition. His treatises are finished works of art, unlike Aristotle's in this respect. They state the main problem first, go through the subject matter in a thorough and businesslike way, and treat special problems by the way or at the last.
The clarity of both Kant and Aristotle may be said to consist in the order that they impose on a subject. We see a philosophical beginning, middle, and end. We also, particularly in the case of Aristotle, are provided with accounts of the views and objections of others, both philosophers and ordinary men.
Thus, in one sense the style of the treatise is similar to the style of the dialogue. But the element of drama is missing from the Kantian or Aristotelean treatise; a philosophical view is developed through straightforward exposition rather than through the conflict of positions and opinions, as in Plato.
3. THE MEETING OF 0BJEcnoNs: The philosophical style developed in the Middle Ages and perfected by St. Thomas Aquinas in his Summa Theologica has likenesses to both of those already discussed. Plato, we have pointed out, raises most of the persistent philosophical problems; and Socrates,
