World (n.) is a concrete concept or an idea, not some enormous aggregate of things as they actually are, but rather it is an aggregate of all objects of possible experience.
The World (n.) is a manufactured article, a construction of the mind. We perceive the top of the table as round, whereas our sensation is of an ellipse.
The World (n.) is orderly not of itself, but because the thought that knows the world is itself an ordering.
The World (n.) rewards not good intentions but knowledge of natural laws and the physical skill to use them; no amount of scrupulous duty guarantees happiness in it.
The World (n.) was, for obscurantist sages, an inn, a penitentiary, a lunatic asylum, a cloaca — the privy of the whole universe; Kant attacked them with unusual vehemence.
The World (n.) without man would be a desert — and for Kant a world without man means a world without spectators.
