Opposing a long-standing orthodoxy of the Western philosophical tradition running from ancient Greek thought until the late nineteenth century, Frege argued that psychological laws of thought—those that explicate how we in fact think—must be distinguished from logical laws of thought—those that formulate and impose rational requirements on thinking. Logic does not describe how we actually think, but only how we should. Yet by thus sundering the logical from the psychological, Frege was unable to explain certain fundamental logical truths, most notably the psychological version of the law of non-contradiction—that one cannot think a thought and its negation simultaneously.

Irad Kimhi’s Thinking and Being marks a radical break with Frege’s legacy in analytic philosophy, exposing the flaws of his approach and outlining a novel conception of judgment as a two-way capacity. In closing the gap that Frege opened, Kimhi shows that the two principles of non-contradiction—the ontological principle and the psychological principle—are in fact aspects of the very same capacity, differently manifested in thinking and being.

As his argument progresses, Kimhi draws on the insights of historical figures such as Aristotle, Kant, and Wittgenstein to develop highly original accounts of topics that are of central importance to logic and philosophy more generally. Self-consciousness, language, and logic are revealed to be but different sides of the same reality. Ultimately, Kimhi’s work elucidates the essential sameness of thinking and being that has exercised Western philosophy since its inception.

Alfred North Whitehead has never gone out of print, but for a time he was decidedly out of fashion in the English-speaking world. In a splendid work that serves as both introduction and erudite commentary, Isabelle Stengers—one of today’s leading philosophers of science—goes straight to the beating heart of Whitehead’s thought. The product of thirty years’ engagement with the mathematician-philosopher’s entire canon, this volume establishes Whitehead as a daring thinker on par with Gilles Deleuze, Felix Guattari, and Michel Foucault.

Reading the texts in broadly chronological order while highlighting major works, Stengers deftly unpacks Whitehead’s often complicated language, explaining the seismic shifts in his thinking and showing how he called into question all that philosophers had considered settled after Descartes and Kant. She demonstrates that the implications of Whitehead’s philosophical theories and specialized knowledge of the various sciences come yoked with his innovative, revisionist take on God. Whitehead’s God exists within a specific epistemological realm created by a radically complex and often highly mathematical language.

“To think with Whitehead today,” Stengers writes, “means to sign on in advance to an adventure that will leave none of the terms we normally use as they were.”

On the creation of the world, and the destruction of Atlantis.

Plato, the great philosopher of Athens, was born in 427 BC. In early manhood an admirer of Socrates, he later founded the famous school of philosophy in the grove Academus. Much else recorded of his life is uncertain; that he left Athens for a time after Socrates’ execution is probable; that later he went to Cyrene, Egypt, and Sicily is possible; that he was wealthy is likely; that he was critical of “advanced” democracy is obvious. He lived to be 80 years old. Linguistic tests including those of computer science still try to establish the order of his extant philosophical dialogues, written in splendid prose and revealing Socrates’ mind fused with Plato’s thought.

In Laches, Charmides, and Lysis, Socrates and others discuss separate ethical conceptions. Protagoras, Ion, and Meno discuss whether righteousness can be taught. In Gorgias, Socrates is estranged from his city’s thought, and his fate is impending. The Apology (not a dialogue), Crito, Euthyphro, and the unforgettable Phaedo relate the trial and death of Socrates and propound the immortality of the soul. In the famous Symposium and Phaedrus, written when Socrates was still alive, we find the origin and meaning of love. Cratylus discusses the nature of language. The great masterpiece in ten books, the Republic, concerns righteousness (and involves education, equality of the sexes, the structure of society, and abolition of slavery). Of the six so-called dialectical dialogues Euthydemus deals with philosophy; metaphysical Parmenides is about general concepts and absolute being; Theaetetus reasons about the theory of knowledge. Of its sequels, Sophist deals with not-being; Politicus with good and bad statesmanship and governments; Philebus with what is good. The Timaeus seeks the origin of the visible universe out of abstract geometrical elements. The unfinished Critias treats of lost Atlantis. Unfinished also is Plato’s last work, Laws, a critical discussion of principles of law which Plato thought the Greeks might accept.

The Loeb Classical Library edition of Plato is in twelve volumes.

An award-winning philosopher bridges the continental-analytic divide with an important contribution to the debate on the meaning of realism.

Jocelyn Benoist argues for a philosophical point of view that prioritizes the concept of reality. The human mind’s attitudes toward reality, he posits, both depend on reality and must navigate within it.

Refusing the path of metaphysical realism, which would make reality an object of speculation in itself, independent of any reflection on our ways of approaching it or thinking about it, Benoist defends the idea of an intentionality placed in reality—contextualized. Intentionality is an essential part of any realist philosophical position; Benoist’s innovation is to insist on looking to context to develop a renewed realism that draws conclusions from contemporary philosophy of language and applies them methodically to issues in the fields of metaphysics and the philosophy of the mind. “What there is”—the traditional subject of metaphysics—can be determined only in context.

Benoist offers a sharp criticism of acontextual ontology and acontextual approaches to the mind and reality. At the same time, he opposes postmodern anti-realism and the semantic approach characteristic of classic analytic philosophy. Instead, Toward a Contextual Realism bridges the analytic-continental divide while providing the foundation for a radically contextualist philosophy of mind and metaphysics. “To be” is to be in a context.
