Aristotelianism (/ˌærɪstəˈtiːliənɪzəm/ ARR-i-stə-TEE-lee-ə-niz-əm) is a philosophical tradition inspired by the work of Aristotle, usually characterized by deductive logic and an analytic inductive method in the study of natural philosophy and metaphysics. It covers the treatment of the social sciences under a system of natural law. It answers why-questions by a scheme of four causes, including purpose or teleology, and emphasizes virtue ethics. Aristotle and his school wrote tractates on physics, biology, metaphysics, logic, ethics, aesthetics, poetry, theatre, music, rhetoric, psychology, linguistics, economics, politics, and government. Any school of thought that takes one of Aristotle's distinctive positions as its starting point can be considered "Aristotelian" in the widest sense. This means that different Aristotelian theories (e.g. in ethics or in ontology) may not have much in common as far as their actual content is concerned besides their shared reference to Aristotle.

In Aristotle's time, philosophy included natural philosophy, which preceded the advent of modern science during the Scientific Revolution. The works of Aristotle were initially defended by the members of the Peripatetic school and later on by the Neoplatonists, who produced many commentaries on Aristotle's writings. In the Islamic Golden Age, Avicenna and Averroes translated the works of Aristotle into Arabic and under them, along with philosophers such as Al-Kindi and Al-Farabi, Aristotelianism became a major part of early Islamic philosophy.

A siege (from Latin sedere 'to sit') is a military blockade of a city, or fortress, with the intent of conquering by attrition, or by well-prepared assault. Siege warfare (also called siegecraft or poliorcetics) is a form of constant, low-intensity conflict characterized by one party holding a strong, static, defensive position. The attacking party is said to be laying siege. Consequently, an opportunity for negotiation between combatants is common, as proximity and fluctuating advantage can encourage diplomacy.

A siege occurs when an attacker encounters a city or fortress that cannot be easily taken by a quick assault, and which refuses to surrender. Sieges involve surrounding the target to block provision of supplies and reinforcement or escape of troops (a tactic known as "investment"). This is typically coupled with attempts to reduce the fortifications by means of siege engines, artillery bombardment, or mining (also known as sapping), or the use of deception or treachery to bypass defenses.

Non-penetrative sex or outercourse is sexual activity that usually does not include sexual penetration, but some forms, particularly when termed outercourse, include penetrative aspects, that may result from forms of fingering or oral sex. It generally excludes the penetrative aspects of vaginal, anal, or oral sex, but includes various forms of sexual and non-sexual activity, such as frottage, manual sex, mutual masturbation, kissing, or hugging.

People engage in non-penetrative sex for a variety of reasons, including as a form of foreplay or as a primary or preferred sexual act. Heterosexual couples may engage in non-penetrative sex as an alternative to penile-vaginal penetration, to preserve virginity, or as a type of birth control. Same-sex couples may also engage in non-penetrative sex to preserve virginity, with gay males using it as an alternative to anal penetration.

Moderate realism (also called immanent realism) is a position in the debate on the metaphysics of universals which holds that there is no realm in which universals exist (in opposition to Platonic realism, which asserts the existence of abstract objects), nor do they really exist within particulars as universals, but rather universals really exist within particulars as particularised, and multiplied.

Umberto Eco OMRI (5 January 1932 – 19 February 2016) was an Italian medievalist, philosopher, semiotician, novelist, cultural critic, and political and social commentator. In English, he is best known for his popular 1980 novel The Name of the Rose, a historical mystery combining semiotics in fiction with biblical analysis, medieval studies and literary theory, as well as Foucault's Pendulum, his 1988 novel which touches on similar themes.

Eco wrote prolifically throughout his life, with his output including children's books, translations from French and English, in addition to a twice-monthly newspaper column "La Bustina di Minerva" (Minerva's Matchbook) in the magazine L'Espresso beginning in 1985, with his last column (a critical appraisal of the Romantic paintings of Francesco Hayez) appearing 27 January 2016. At the time of his death, he was an Emeritus professor at the University of Bologna, where he taught for much of his life. In the 21st century, he has continued to gain recognition for his 1995 essay "Ur-Fascism", where Eco lists fourteen general properties he believes comprise fascist ideologies.

In Greek mythology, Alcinous (also Alcinoüs; /ælˈsɪnəʊəs/; Ancient Greek: Ἀλκίνοος Alkínoos lit. 'mighty mind') was a son of Nausithous and brother of Rhexenor. After the latter's death, he married his brother's daughter Arete who bore him Nausicaa, Halius, Clytoneus and Laodamas. In some accounts, Alcinous' father was Phaeax, son of Poseidon and Corcyra, and brother of Locrus.
