19th-century philosophyIn the 19th century, the philosophers of the 18th-century Enlightenment began to have a dramatic effect on subsequent developments in philosophy. In particular, the works of Immanuel Kant gave rise to a new generation of German philosophers and began to see wider recognition internationally. Also, in a reaction to the Enlightenment, a movement called Romanticism began to develop towards the end of the 18th century.
NominalismIn metaphysics, nominalism is the view that universals and abstract objects do not actually exist other than being merely names or labels. There are at least two main versions of nominalism. One version denies the existence of universals - things that can be instantiated or exemplified by many particular things (e.g., strength, humanity). The other version specifically denies the existence of abstract objects - objects that do not exist in space and time.
NovalisGeorg Philipp Friedrich Freiherr von Hardenberg (2 May 1772 – 25 March 1801), pen name Novalis (noˈvaːlɪs), was a German aristocrat and polymath, who was a poet, novelist, philosopher and mystic. He is regarded as an influential figure of Jena Romanticism. Novalis was born into a minor aristocratic family in Electoral Saxony. He was the second of eleven children; his early household observed a strict Pietist faith. He studied law at the University of Jena, the University of Leipzig, and the University of Wittenberg.
PlatonismPlatonism is the philosophy of Plato and philosophical systems closely derived from it, though contemporary Platonists do not necessarily accept all doctrines of Plato. Platonism had a profound effect on Western thought. In its most basic fundamentals, 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.
Unity of scienceThe unity of science is a thesis in philosophy of science that says that all the sciences form a unified whole. The variants of the thesis can be classified as ontological (giving a unified account of the structure of reality) and/or as epistemic/pragmatic (giving a unified account of how the activities and products of science work). There are also philosophers who emphasize the disunity of science, which does not necessarily imply that there could be no unity in some sense but does emphasize pluralism in the ontology and/or practice of science.
XenophanesXenophanes of Colophon (zəˈnɒfəniːz ; Ξενοφάνης ὁ Κολοφώνιος ksenophánɛːs ho kolophɔ̌ːnios; c. 570 – c. 478 BC) was a Greek philosopher, theologian, poet, and critic of Homer from Ionia who travelled throughout the Greek-speaking world in early Classical Antiquity. As a poet, Xenophanes was known for his critical style, writing poems that are considered among the first satires. He also composed elegiac couplets that criticised his society's traditional values of wealth, excesses, and athletic victories.
Vienna CircleThe Vienna Circle (Wiener Kreis) of logical empiricism was a group of elite philosophers and scientists drawn from the natural and social sciences, logic and mathematics who met regularly from 1924 to 1936 at the University of Vienna, chaired by Moritz Schlick. The Vienna Circle had a profound influence on 20th-century philosophy, especially philosophy of science and analytic philosophy. The philosophical position of the Vienna Circle was called logical empiricism (German: logischer Empirismus), logical positivism or neopositivism.
Antiochus of AscalonAntiochus of Ascalon (ænˈtaɪəkəs; Άντίοχος ὁ Ἀσκαλώνιος; c. 135/130 – c. 68 BC) was an 1st century BC Platonism philosopher who rejected skepticism and blended Stoic doctrines with Platonism as the first philosopher in the tradition of Middle Platonism. Antiochus moved to Athens early in his life and became a pupil of Philo of Larissa at the Platonic Academy, but he went on to reject the prevailing Academic skepticism of Philo and his predecessors.
NeoplatonismNeoplatonism is a version of Platonic philosophy that emerged in the 3rd century AD against the background of Hellenistic philosophy and religion. The term does not encapsulate a set of ideas as much as a series of thinkers. Among the common ideas it maintains is monism, the doctrine that all of reality can be derived from a single principle, "the One". Neoplatonism began with Ammonius Saccas and his student Plotinus (c. 204/5–271 AD) and stretched to the 6th century AD.
ProtagorasProtagoras (prəʊˈtægəˌræs; Πρωταγόρας; 490 BC-420 BC) was a pre-Socratic Greek philosopher and rhetorical theorist. He is numbered as one of the sophists by Plato. In his dialogue Protagoras, Plato credits him with inventing the role of the professional sophist.
