Republic (Plato) in the context of "Atlantis"

Platonism is the philosophy of Plato and philosophical systems closely derived from it, though later and contemporary Platonists do not necessarily accept all of Plato's own doctrines. Platonism has had a profound effect on Western thought. At the most fundamental level, Platonism affirms the existence of abstract objects, which are asserted to exist in a third realm distinct from both the sensible external world and from the internal world of consciousness, and is the opposite of nominalism. This can apply to properties, types, propositions, meanings, numbers, sets, truth values, and so on (see abstract object theory). Philosophers who affirm the existence of abstract objects are sometimes called Platonists; those who deny their existence are sometimes called nominalists. The terms "Platonism" and "nominalism" also have established senses in the history of philosophy. They denote positions that have little to do with the modern notion of an abstract object.

In a narrower sense, the term might indicate the doctrine of Platonic realism, a form of mysticism. The central concept of Platonism, a distinction essential to the Theory of Forms, is the distinction between the reality which is perceptible but unintelligible, associated with the flux of Heraclitus and studied by the likes of physical science, and the reality which is imperceptible but intelligible, associated with the unchanging being of Parmenides and studied by the likes of mathematics. Geometry was the main motivation of Plato, and this also shows the influence of Pythagoras. The Forms are typically described in dialogues such as the Phaedo, Symposium and Republic as perfect archetypes of which objects in the everyday world are imperfect copies. Aristotle's Third Man Argument is its most famous criticism in antiquity.

The dithyramb (/ˈdɪθɪræm/; Ancient Greek: διθύραμβος, dithyrambos) was an ancient Greek hymn sung and danced in honor of Dionysus, the god of wine and fertility; the term was also used as an epithet of the god. Plato, in The Laws, while discussing various kinds of music mentions "the birth of Dionysos, called, I think, the dithyramb." Plato also remarks in the Republic that dithyrambs are the clearest example of poetry in which the poet is the only speaker.

However, in The Apology Socrates went to the dithyrambic poetswith some of their own most elaborate passages, asking their meaning, but got a response of, "Will you believe me?" which "showed me in an instant that not by wisdom do poets write poetry, but by a sort of genius and inspiration; they are like diviners or soothsayers who also say many fine things, but do not understand the meaning of them."

The Laws (Ancient Greek: Νόμοι) is Plato's last and longest dialogue. The conversation depicted in the work's twelve books begins with the question of who is given the credit for establishing a civilization's laws. Its musings on the ethics of government and law have frequently been compared to Plato's more widely read Republic. Some scholars see this as the work of Plato as an older man having failed in his effort to guide the rule of the tyrant Dionysius II of Syracuse. These events are alluded to in the Seventh Letter. The text is noteworthy as the only Platonic dialogue not to feature Socrates.

Conflict theories are perspectives in political philosophy and sociology which argue that individuals and groups (social classes) within society interact on the basis of conflict rather than agreement, while also emphasizing social psychology, historical materialism, power dynamics, and their roles in creating power structures, social movements, and social arrangements within a society. Conflict theories often draw attention to power differentials, such as class conflict, or a conflict continuum. Power generally contrasts historically dominant ideologies, economies, currencies or technologies. Accordingly, conflict theories represent attempts at the macro-level analysis of society.

Many political philosophers and sociologists have been framed as having conflict theories, dating back as far as Plato's idea of the tripartite soul of The Republic, to Hobbes' ideas in The Leviathan. Other historical political philosophers associated with having "conflict theories" include Jean Bodin, Adam Smith, John Stuart Mill, Thomas Robert Malthus, Karl Marx, and Georg Simmel. Georg Simmel was one of the earliest sociologists to formally use "conflict" as a framework to understand social change, writing about the topic in his 1908 book, "Conflict and the Web of Group Affiliations".

The Nag Hammadi library (also known as the Chenoboskion Manuscripts and the Gnostic Gospels) is a collection of early Christian and Gnostic texts discovered near the Upper Egyptian town of Nag Hammadi in 1945.

Twelve leather-bound papyrus codices (and a tractate from a thirteenth) buried in a sealed jar were found by an Egyptian farmer named Muhammed al-Samman and others in late 1945. The writings in these codices comprise 52 mostly Gnostic treatises, but also three works belonging to the Corpus Hermeticum, and a partial translation/alteration of Plato's Republic. In his introduction to The Nag Hammadi Library in English, James Robinson suggests that these codices may have belonged to a nearby Pachomian monastery and were buried after Saint Athanasius condemned the use of non-canonical books in his Festal Letter of 367 A.D. The Pachomian hypothesis has been further expanded by Lundhaug & Jenott (2015, 2018) and further strengthened by Linjamaa (2024). In his 2024 book, Linjamaa argues that the Nag Hammadi library was used by a small intellectual monastic elite at a Pachomian monastery, and that they were used as a smaller part of a much wider Christian library.

This article lists forms of government and political systems, which are not mutually exclusive, and often have much in common. According to Yale professor Juan José Linz there are three main types of political systems today: democracies, totalitarian regimes and, sitting between these two, authoritarian regimes with hybrid regimes. Another modern classification system includes monarchies as a standalone entity or as a hybrid system of the main three. Scholars generally refer to a dictatorship as either a form of authoritarianism or totalitarianism.

The ancient Greek philosopher Plato discusses in the Republic five types of regimes: aristocracy, timocracy, oligarchy, democracy, and tyranny. The question raised by Plato in the Republic: What kind of state is best? Generational changes informed by new political and cultural beliefs, technological progress, values and morality over millenniums have resulted in considerable shifts in the belief about the origination of political authority, who may participate in matters of state, how people might participate, the determination of what is just, and so forth.
