How would Plato have responded if his student Aristotle had ever challenged his idea that our senses perceive nothing more than the shadows cast upon a wall by a true world of perfect ideals? What would Charles Darwin have said to Karl Marx about his claim that dialectical materialism is a scientific theory of evolution? How would Jean-Paul Sartre have reacted to Simone de Beauvoir’s claim that the Marquis de Sade was a philosopher worthy of serious attention? This light-hearted book proposes answers to such questions by imagining dialogues between thirty-three pairs of philosophical sages who were alive at the same time. Sometime famous sages get a much rougher handling than usual, as when Adam Smith beards Immanuel Kant in his Konigsberg den. Sometimes neglected or maligned sages get a chance to say what they really believed, as when Epicurus explains that he wasn’t epicurean. Sometimes the dialogues are about the origins of modern concepts, as when Blaise Pascal and Pierre de Fermat discuss their invention of probability, or when John Nash and John von Neumann discuss the creation of game theory. Even in these scientific cases, the intention is that the protagonists come across as fallible human beings like the rest of us, rather than the intellectual paragons of philosophical textbooks.

Hosle covers the development of the philosophical dialogue beginning with Plato to the late twentieth century, providing a taxonomy and doctrine of categories.

'Intellectual Entertainments' consists of eight philosophical dialogues, each with five participants, some living, some imaginary and some dead. The dialogues take place either in Elysium or in an imaginary Oxford Common Room. Each historical figure speaks in his own idiom with a distinctive turn of phrase. The imaginary figures speak in the accent and idiom of their respective countries (English, Scottish, American, Australian). The themes are the nature of the mind and the relation between mind and body; the nature of consciousness and its demystification; the nature of thought and its relation to speech; and the objectivity or subjectivity of perceptual qualities such as colour, sound, smell, taste and warmth. Each participant presents a different point of view and defends his position against the arguments of the others. No philosophical knowledge is presupposed.

The Republic is a Socratic dialogue, written by Plato around 380 BCE, concerning the definition of justice, the order and character of the just city-state and the just man. The dramatic date of the dialogue has been much debated and though it must take place some time during the Peloponnesian War, "there would be jarring anachronisms if any of the candidate specific dates between 432 and 404 were assigned". It is Plato's best-known work and has proven to be one of the most intellectually and historically influential works of philosophy and political theory. In it, Socrates along with various Athenians and foreigners discuss the meaning of justice and examine whether or not the just man is happier than the unjust man by considering a series of different cities coming into existence "in speech", culminating in a city (Kallipolis) ruled by philosopher-kings; and by examining the nature of existing regimes. The participants also discuss the theory of forms, the immortality of the soul, and the roles of the philosopher and of poetry in society.

“Witty and profound” musings on questions of art and religion from a celebrated novelist known for her philosophical explorations (Library Journal). For centuries, the works of Plato, featuring his mentor and teacher Socrates, have illuminated philosophical discussions. In Acastos: Two Platonic Dialogues, acclaimed philosopher, poet, and writer Iris Murdoch turns her keen eye to the value of art, knowledge, and faith, with two dramatic conversations featuring Plato and Socrates. “Art and Eros”: After witnessing a theatrical performance, Socrates and his pupils—Callistos, Acastos, Mantias, Deximenes, and Plato—undertake a quest to uncover the meaning and worth of artistic endeavors. “Above the Gods”: The celebration of a religious festival leads to a lively discussion of the gods and their place in society, as Socrates, along with several of his followers, talk about the morality of religion, wisdom, and righteousness. Told through vivid characterizations and lively discourse, Acastos is at once a “profound and satisfying” exploration of the Socratic method and an enjoyable example of theatrical writing from a Man Booker Prize–winning novelist known for her studies with Ludwig Wittgenstein and her philosophy lectures at Oxford University, as well as for such works of fiction as The Sea, The Sea and The Black Prince (Kirkus Reviews).
