C. S. Lewis Quote
If ants had a language they would, no doubt, call their anthill an artifact and describe the brick wall in its neighborhood an a natural object. Nature in fact would be for them all that was not "ant-made." Just so, for us, nature is all that is not man-made; the natural state of anything is its state when not modified by man.
