Nature is our eldest mother; she will do no harm.

We were never intimate mother and children while she was our mother - but... when she became our child, the affection came.

How strange that nature does not knock, and yet does not intrude!

Nature is a haunted house--but Art--is a house that tries to be haunted.

Nature is what we know - Yet have not art to say - So impotent our wisdom is To her simplicity

Self-defence is Nature's eldest law.
