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
What more felicitie can fall to creature
Than to enjoy delight with libertie,
And to be lord of all the workes of Nature,
To raine in th' aire from earth to highest skie,
To feed on flowres and weeds of glorious feature.
Edmund Spenser, The Fate of the Butterfly, line 209.
