Summum bonumSummum bonum is a Latin expression meaning the highest or ultimate good, which was introduced by the Roman philosopher Cicero to denote the fundamental principle on which some system of ethics is based — that is, the aim of actions, which, if consistently pursued, will lead to the best possible life. Since Cicero, the expression has acquired a secondary meaning as the essence or ultimate metaphysical principle of Goodness itself, or what Plato called the Form of the Good. These two meanings do not necessarily coincide.
Rhetoric (Aristotle)Aristotle's Rhetoric (Rhētorikḗ; Ars Rhetorica) is an ancient Greek treatise on the art of persuasion, dating from . The English title varies: typically it is Rhetoric, the Art of Rhetoric, On Rhetoric, or a Treatise on Rhetoric. Aristotle is credited with developing the basics of a system of rhetoric that "thereafter served as [the] touchstone" of the discipline, influencing the development of rhetorical theory from ancient through modern times. The Rhetoric is regarded by most rhetoricians as "the most important single work on persuasion ever written.
Golden mean (philosophy)The golden mean or golden middle way is the desirable middle between two extremes, one of excess and the other of deficiency. It appeared in Greek thought at least as early as the Delphic maxim "nothing in excess", was discussed in Plato's Philebus. Aristotle analyzed the golden mean in the Nicomachean Ethics Book II: That virtues of character can be described as means. It was subsequently emphasized in Aristotelian virtue ethics. For example, in the Aristotelian view, courage is a virtue, but if taken to excess would manifest as recklessness, and, in deficiency, cowardice.
TechneIn Ancient Greek philosophy, techne (tékhnē; tékhnɛː, ˈtexni) is a philosophical concept that refers to making or doing. Many Ancient Greek philosophers, such as Socrates, Plato, and Aristotle, had difficulty coming up with a single definition for techne and there is differentiation between the ways that these philosophers used the term. Today the modern definition and use of the term practical knowledge is similar to the Ancient Greek definition of techne. The word techne comes from the Greek word for art.
PhilebusThe Philebus (fɪˈliːbəs; occasionally given as Philebos; Greek: Φίληβος) is a Socratic dialogue written in the 4th century BC by Plato. Besides Socrates (the main speaker) the other interlocutors are Philebus and Protarchus. Philebus, who advocates the life of physical pleasure (hedonism), hardly participates, and his position is instead defended by Protarchus, who learnt argumentation from Sophists. Socrates proposes there are higher pleasures (such as those of the mind) as well as lower ones, and asks if the best life isn't one that optimally mixes both.
Praxis (process)Praxis is the process by which a theory, lesson, or skill is enacted, embodied, realized, applied, or put into practice. "Praxis" may also refer to the act of engaging, applying, exercising, realizing, or practising ideas. This has been a recurrent topic in the field of philosophy, discussed in the writings of Plato, Aristotle, St. Augustine, Francis Bacon, Immanuel Kant, Søren Kierkegaard, Ludwig von Mises, Karl Marx, Antonio Gramsci, Martin Heidegger, Hannah Arendt, Jean-Paul Sartre, Paulo Freire, Murray Rothbard, and many others.
EthosEthos (ˈiːθɒs or USˈiːθoʊs) is a Greek word meaning "character" that is used to describe the guiding beliefs or ideals that characterize a community, nation, or ideology; and the balance between caution, and passion. The Greeks also used this word to refer to the power of music to influence emotions, behaviors, and even morals. Early Greek stories of Orpheus exhibit this idea in a compelling way. The word's use in rhetoric is closely based on the Greek terminology used by Aristotle in his concept of the three artistic proofs or modes of persuasion.
Renaissance philosophyThe designation "Renaissance philosophy" is used by historians of philosophy to refer to the thought of the period running in Europe roughly between 1400 and 1600. It therefore overlaps both with late medieval philosophy, which in the fourteenth and fifteenth centuries was influenced by notable figures such as Albert the Great, Thomas Aquinas, William of Ockham, and Marsilius of Padua, and early modern philosophy, which conventionally starts with René Descartes and his publication of the Discourse on Method in 1637.
PotentialPotential generally refers to a currently unrealized ability. The term is used in a wide variety of fields, from physics to the social sciences to indicate things that are in a state where they are able to change in ways ranging from the simple release of energy by objects to the realization of abilities in people. The philosopher Aristotle incorporated this concept into his theory of potentiality and actuality, a pair of closely connected principles which he used to analyze motion, causality, ethics, and physiology in his Physics, Metaphysics, Nicomachean Ethics, and De Anima, which is about the human psyche.
SpeusippusSpeusippus (spjuːˈsɪpəs; Σπεύσιππος; c. 408 – 339/8 BC) was an ancient Greek philosopher. Speusippus was Plato's nephew by his sister Potone. After Plato's death, c. 348 BC, Speusippus inherited the Academy, near age 60, and remained its head for the next eight years. However, following a stroke, he passed the chair to Xenocrates. Although the successor to Plato in the Academy, Speusippus frequently diverged from Plato's teachings.
