WThe phrase "the best of all possible worlds" was coined by the German polymath and Enlightenment philosopher Gottfried Leibniz in his 1710 work Essais de Théodicée sur la bonté de Dieu, la liberté de l'homme et l'origine du mal. The claim that the actual world is the best of all possible worlds is the central argument in Leibniz's theodicy, or his attempt to solve the problem of evil.
WThe chicken or the egg causality dilemma is commonly stated as the question, "which came first: the chicken or the egg?" The dilemma stems from the observation that all chickens hatch from eggs and all chicken eggs are laid by chickens. "Chicken-and-egg" is a metaphoric adjective describing situations where it is not clear which of two events should be considered the cause and which should be considered the effect, to express a scenario of infinite regress, or to express the difficulty of sequencing actions where each seems to depend on others being done first. Plutarch posed the question as a philosophical matter in his essay "The Symposiacs", written in the 1st century CE.
WThe Latin cogito, ergo sum, usually translated into English as "I think, therefore I am", is a philosophical statement that was made by René Descartes. The phrase originally appeared in French as je pense, donc je suis in his 1637 Discourse on the Method, so as to reach a wider audience than Latin would have allowed. It appeared in Latin in his later Principles of Philosophy. The dictum is also sometimes referred to as the cogito. As Descartes explained it, "we cannot doubt of our existence while we doubt." A fuller version, articulated by Antoine Léonard Thomas, aptly captures Descartes' intent: dubito, ergo cogito, ergo sum.
WNo Exit is a 1944 existentialist French play by Jean-Paul Sartre. The original title is the French equivalent of the legal term in camera, referring to a private discussion behind closed doors. The play was first performed at the Théâtre du Vieux-Colombier in May 1944. The play begins with three characters who find themselves waiting in a mysterious room. It is a depiction of the afterlife in which three deceased characters are punished by being locked into a room together for eternity. It is the source of Sartre's especially famous phrase "L'enfer, c'est les autres" or "Hell is other people", a reference to Sartre's ideas about the look and the perpetual ontological struggle of being caused to see oneself as an object from the view of another consciousness.
WHomo homini lupus, or in its unabridged form Homo homini lupus est, is a Latin proverb meaning "A man is a wolf to another man," or more tersely "Man is wolf to man."

The wolf as a creature is thought, in this example, to have qualities of being predatory, cruel, inhuman i.e. more like an animal than civilized.

WThe Latin maxim ignoramus et ignorabimus, meaning "we do not know and will not know," represents the idea that scientific knowledge is limited. It was popularized by Emil du Bois-Reymond, a German physiologist, in his 1872 address "Über die Grenzen des Naturerkennens"
WThe Ancient Greek aphorism "know thyself" is one of the Delphic maxims and was the first of three maxims inscribed in the pronaos (forecourt) of the Temple of Apollo at Delphi according to the Greek writer Pausanias (10.24.1).

McLuhan proposes that a communication medium itself, not the messages it carries, should be the primary focus of study. He showed that artifacts as media affect any society by their characteristics, or content.
