Four causesThe four causes or four explanations are, in Aristotelian thought, four fundamental types of answer to the question "why?", in analysis of change or movement in nature: the material, the formal, the efficient, and the final. Aristotle wrote that "we do not have knowledge of a thing until we have grasped its why, that is to say, its cause." While there are cases in which classifying a "cause" is difficult, or in which "causes" might merge, Aristotle held that his four "causes" provided an analytical scheme of general applicability.
Ancient philosophyThis page lists some links to ancient philosophy, namely philosophical thought extending as far as early post-classical history (600 CE). Genuine philosophical thought, depending upon original individual insights, arose in many cultures roughly contemporaneously. Karl Jaspers termed the intense period of philosophical development beginning around the 7th century BCE and concluding around the 3rd century BCE an Axial Age in human thought.
GeistGeist (ˈɡaɪst) is a German noun with a significant degree of importance in German philosophy. Its semantic field corresponds to English ghost, spirit, mind, intellect. Some English translators resort to using "spirit/mind" or "spirit (mind)" to help convey the meaning of the term. Geist is also a central concept in Georg Wilhelm Friedrich Hegel's 1807 The Phenomenology of Spirit (Phänomenologie des Geistes). Notable compounds, all associated with Hegel's view of world history of the late 18th century, include Weltgeist "world-spirit", Volksgeist "national spirit" and Zeitgeist "spirit of the age".
AristotleAristotle (ˈærᵻstɒtəl; Ἀριστοτέλης Aristotélēs, aristotélɛːs; 384–322 BC) was an Ancient Greek philosopher and polymath. His writings cover a broad range of subjects spanning the natural sciences, philosophy, linguistics, economics, politics, psychology and the arts. As the founder of the Peripatetic school of philosophy in the Lyceum in Athens, he began the wider Aristotelian tradition that followed, which set the groundwork for the development of modern science. Little is known about Aristotle's life.
AristophanesAristophanes (ˌærɪˈstɒfəniːz; Ἀριστοφάνης, aristophánɛːs; c. 446 – c. 386 BC), son of Philippus, of the deme Kydathenaion (Cydathenaeum), was a comic playwright or comedy-writer of ancient Athens and a poet of Old Attic Comedy. Eleven of his forty plays survive virtually complete. These provide the most valuable examples of a genre of comic drama known as Old Comedy and are used to define it, along with fragments from dozens of lost plays by Aristophanes and his contemporaries.
XenophonXenophon of Athens (ˈzɛnəfən,zi-,-fɒn; Ξενοφῶν ksenophɔ̂ːn; 430 – probably 355 or 354 BC) was a Greek military leader, philosopher, and historian, born in Athens. At the age of 30, Xenophon was elected commander of one of the biggest Greek mercenary armies of the Achaemenid Empire, the Ten Thousand, that marched on and came close to capturing Babylon in 401 BC. As the military historian Theodore Ayrault Dodge wrote, "the centuries since have devised nothing to surpass the genius of this warrior".
CiceroMarcus Tullius Cicero (ˈsɪsəroʊ ; ˈmaːrkʊs ˈtʊlli.ʊs ˈkɪkɛroː; 3 January 106 BC – 7 December 43 BC) was a Roman statesman, lawyer, scholar, philosopher, writer and Academic skeptic, who tried to uphold optimate principles during the political crises that led to the establishment of the Roman Empire. His extensive writings include treatises on rhetoric, philosophy and politics. He is considered one of Rome's greatest orators and prose stylists and the innovator of what became known as "Ciceronian rhetoric".
Phaedrus (dialogue)The Phaedrus (ˈfiːdrəs; Phaidros), written by Plato, is a dialogue between Socrates, and Phaedrus, an interlocutor in several dialogues. The Phaedrus was presumably composed around 370 BC, about the same time as Plato's Republic and Symposium. Although ostensibly about the topic of love, the discussion in the dialogue revolves around the art of rhetoric and how it should be practiced, and dwells on subjects as diverse as metempsychosis (the Greek tradition of reincarnation) and erotic love, and the nature of the human soul shown in the famous Chariot Allegory.
ParmenidesParmenides of Elea (pɑːrˈmɛnɪdiːz...ˈɛliə; Παρμενίδης ὁ Ἐλεάτης; fl. late sixth or early fifth century BC) was a pre-Socratic Greek philosopher from Elea in Magna Graecia. Parmenides was born in the Greek colony of Elea, from a wealthy and illustrious family. His dates are uncertain; according to doxographer Diogenes Laërtius, he flourished just before 500 BC, which would put his year of birth near 540 BC, but in the dialogue Parmenides Plato has him visiting Athens at the age of 65, when Socrates was a young man, c.
Cynicism (philosophy)Cynicism (κυνισμός) is a school of thought in ancient Greek philosophy, originating in the Classical period and extending into the Hellenistic and Roman Imperial periods. According to Cynicism, people are reasoning animals and the purpose of life and the way to gain happiness is to achieve virtue, in agreement with nature, following one's natural sense of reason by living ascetically and shamelessly free from social constraints.
