Nature
Nature, in the broadest sense, is the natural, physical, or material world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena.
Nature
A nation may be said to consist of its territory, its people, and its laws. The territory is the only part which is of certain durability. "One generation passeth away and another generation cometh, but the earth abideth forever."
Abraham Lincoln, Message to Congress (1 December 1862)
Teachers
Schoolmasters will I keep within my house,
Fit to instruct her youth. * * *
* * * To cunning men
I will be very kind, and liberal
To mine own children in good bringing up.
William Shakespeare, The Taming of the Shrew (c. 1593-94), Act I, scene 1, line 94.
