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
Yet neither spinnes, nor cards, ne cares nor fretts,
But to her mother Nature all her care she letts.
Edmund Spenser, The Faerie Queene (1589-96), Book II, Canto VI.
