Parens argues that Alfarabi, the tenth-century Muslim philosopher, demonstrated that Plato is not the originator of Western metaphysics, and that what appears to be Plato's metaphysics was intended as a rhetorical defense of his politics.

by the question in its being an answer, if only in a circumstantial (i. e. inessential) manner. One indeed must question oneself in order to remember, says Plato, but the dialectic, which would be scientific, must be something else even if it remains a play of question and answer. This contradiction did not escape Aristotle: he split the scientific from the dialectic and logic from argumentation whose respective theories he was led to conceive in order to clearly define their boundaries and specificities. As for Plato, he found in the famous theory of Ideas what he sought in order to justify knowledge as that which is supposed to hold its truth only from itself. What do Ideas mean within the framework of our approach? In what consists the passage from rhetoric to ontology which leads to the denaturation of argumentation? When Socrates asked, for example, "What is virtue?", he thought one could not answer such a question because the answer refers to a single proposition, a single truth, whereas the formulation of the question itself does not indicate this unicity. For any answer, another can be given and thus continuously, if necessary, until eventually one will come across an incompatibility. Now, to a question as to what X, Y, or Z is, one can answer in many ways and nothing in the question itself prohibits multiplicity. Virtue is courage, is justice, and so on.

Philosophy and rhetoric are both old enemies and old friends. In The Rhetorical Sense of Philosophy, Donald Phillip Verene sets out to shift our understanding of the relationship between philosophy and rhetoric from that of separation to one of close association. He outlines how ancient rhetors focused on the impact of language regardless of truth, ancient philosophers utilized language to test truth; and ultimately, this separation of right reasoning from rhetoric has remained intact throughout history. It is time, Verene argues, to reassess this ancient and misunderstood relationship. Verene traces his argument utilizing the writing of ancient and modern authors from Plato and Aristotle to Descartes and Kant; he also explores the quarrel between philosophy and poetry, as well as the nature of speculative philosophy. Verene's argument culminates in a unique analysis of the frontispiece as a rhetorical device in the works of Hobbes, Vico, and Rousseau. Verene bridges the stubborn gap between these two fields, arguing that rhetorical speech both brings philosophical speech into existence and allows it to endure and be understood. The Rhetorical Sense of Philosophy depicts the inevitable intersection between philosophy and rhetoric, powerfully illuminating how a rhetorical sense of philosophy is an attitude of mind that does not separate philosophy from its own use of language.

By going back to the Italian humanist tradition and aspects of earlier Greek and Latin thought, Ernesto Grassi develops a conception of rhetoric as the basis of philosophy. Grassi explores the sense in which the first principles of rational thought come from the metaphorical power of the word. He finds the basis for his conception in the last great thinker of the Italian humanist tradition, Giambattista Vico (1668-1744). He concentrates on Vico's understanding of imagination and the sense of human ingenuity contained in metaphor. For Grassi, rhetorical activity is the essence and inner life of thought when connected to the metaphorical power of the word. Originally published in English in 1980, Rhetoric as Philosophy has been out of print for some time. In his foreword to this reprint edition, Burke scholar Timothy W. Crusius rues the lack of concentrated attention to Grassi because "what he had to say about rhetoric is at least as significant as, for example, what Kenneth Burke taught us".

Plato isn’t exactly thought of as a champion of democracy, and perhaps even less as an important rhetorical theorist. In this book, James L. Kastely recasts Plato in just these lights, offering a vivid new reading of one of Plato’s most important works: the Republic. At heart, Kastely demonstrates, the Republic is a democratic epic poem and pioneering work in rhetorical theory. Examining issues of justice, communication, persuasion, and audience, he uncovers a seedbed of theoretical ideas that resonate all the way up to our contemporary democratic practices. As Kastely shows, the Republic begins with two interrelated crises: one rhetorical, one philosophical. In the first, democracy is defended by a discourse of justice, but no one can take this discourse seriously because no one can see—in a world where the powerful dominate the weak—how justice is a value in itself. That value must be found philosophically, but philosophy, as Plato and Socrates understand it, can reach only the very few. In order to reach its larger political audience, it must become rhetoric; it must become a persuasive part of the larger culture—which, at that time, meant epic poetry. Tracing how Plato and Socrates formulate this transformation in the Republic, Kastely isolates a crucial theory of persuasion that is central to how we talk together about justice and organize ourselves according to democratic principles.

RHETORIC the counterpart of Dialectic. Both alike are concerned with such things as come more or less within the general ken of all men and belong to no definite science. Accordingly all men make use more or less of both; for to a certain extent all men attempt to discuss statements and to maintain them to defend themselves and to attack others. Ordinary people do this either at random or through practice and from acquired habit. Both ways being possible the subject can plainly be handled systematically for it is possible to inquire the reason why some speakers succeed through practice and others spontaneously; and every one will at once agree that such an inquiry is the function of an art.
