Classical elementThe classical elements typically refer to earth, water, air, fire, and (later) aether which were proposed to explain the nature and complexity of all matter in terms of simpler substances. Ancient cultures in Greece, Tibet, and India had similar lists which sometimes referred, in local languages, to "air" as "wind" and the fifth element as "void". These different cultures and even individual philosophers had widely varying explanations concerning their attributes and how they related to observable phenomena as well as cosmology.
ProclusProclus Lycius (ˈprɒkləs_laɪˈsiəs; 8 February 412 – 17 April 485), called Proclus the Successor (Πρόκλος ὁ Διάδοχος, Próklos ho Diádokhos), was a Greek Neoplatonist philosopher, one of the last major classical philosophers of late antiquity. He set forth one of the most elaborate and fully developed systems of Neoplatonism and, through later interpreters and translators, exerted an influence on Byzantine philosophy, Early Islamic philosophy, and Scholastic philosophy.
Fire (classical element)Fire is one of the four classical elements along with earth, water and air in ancient Greek philosophy and science. Fire is considered to be both hot and dry and, according to Plato, is associated with the tetrahedron. Fire is one of the four classical elements in ancient Greek philosophy and science. It was commonly associated with the qualities of energy, assertiveness, and passion. In one Greek myth, Prometheus stole fire from the gods to protect the otherwise helpless humans, but was punished for this charity.
AtlantisAtlantis () is a fictional island mentioned in Plato's works Timaeus and Critias as part of an allegory on the hubris of nations. In the story, Atlantis is described as a naval empire that ruled all Western parts of the known world, making it the literary counter-image of the Achaemenid Empire. After an ill-fated attempt to conquer "Ancient Athens," Atlantis falls out of favor with the deities and submerges into the Atlantic Ocean.
BasilidesBasilides (Greek: Βασιλείδης) was an early Christian Gnostic religious teacher in Alexandria, Egypt who taught from 117 to 138 AD, and claimed to have inherited his teachings from the apostle Saint Matthias. He was a pupil of either the Simonian teacher Menander, or a supposed disciple of Peter named Glaucias. The Acts of the Disputation with Manes state that for a time he taught among the Persians. According to Agapius of Hierapolis he appeared in the 15th year of Trajan reign (113 AD).
Anima mundiThe anima mundi (Greek: ψυχὴ κόσμου, psychè kósmou) or world soul is, according to several systems of thought, an intrinsic connection between all living beings, which relates to the world in much the same way as the soul is connected to the human body. Although the concept of the anima mundi originated in classical antiquity, similar ideas can be found in the thoughts of later European philosophers such as those of Baruch Spinoza, Gottfried Leibniz, Immanuel Kant, Friedrich Schelling, and Georg W.F.
Creatio ex nihiloCreatio ex nihilo (Latin for "creation out of nothing") is the doctrine that matter is not eternal but had to be created by some divine creative act. It is a theistic answer to the question of how the universe comes to exist. It is in contrast to Ex nihilo nihil fit or "nothing comes from nothing", which means that all things were formed from preexisting things; an idea by the Greek philosopher Parmenides (c. 540 – c. 480 BC) about the nature of all things, and later more formally stated by Titus Lucretius Carus (c.
Aether (classical element)According to ancient and medieval science, aether (ˈiːθər, alternative spellings include æther, aither, and ether), also known as the fifth element or quintessence, is the material that fills the region of the universe beyond the terrestrial sphere. The concept of aether was used in several theories to explain several natural phenomena, such as the propagation of light and gravity.
Sophist (dialogue)The Sophist (Σοφιστής; Sophista) is a Platonic dialogue from the philosopher's late period, most likely written in 360 BC. In it the interlocutors, led by Eleatic Stranger employ the method of division in order to classify and define the sophist and describe his essential attributes and differentia vis a vis the philosopher and statesman. Like its sequel, the Statesman, the dialogue is unusual in that Socrates is present but plays only a minor role. Instead, the Eleatic Stranger takes the lead in the discussion.
Parmenides (dialogue)Parmenides (Παρμενίδης) is one of the dialogues of Plato. It is widely considered to be one of the most challenging and enigmatic of Plato's dialogues. The Parmenides purports to be an account of a meeting between the two great philosophers of the Eleatic school, Parmenides and Zeno of Elea, and a young Socrates. The occasion of the meeting was the reading by Zeno of his treatise defending Parmenidean monism against those partisans of plurality who asserted that Parmenides' supposition that there is a one gives rise to intolerable absurdities and contradictions.
