World
The world is the planet Earth and all life upon it, including human civilization. In a philosophical context, the "world" is the whole of the physical Universe, or an ontological world (the "world" of an individual). In a theological context, the world is the material or the profane sphere, as opposed to the celestial, spiritual, transcendent or sacred spheres. "End of the world" scenarios refer to the end of human history, often in religious contexts.
World
The world is a looking glass, and gives back to every man the reflection of his own face. Frown at it and it will in turn look sourly upon you; laugh at it and with it, and it is a jolly kind companion.
William Makepeace Thackeray, Vanity Fair; reported in Hoyt's New Cyclopedia Of Practical Quotations (1922), p. 911-17.
