A child-like man is not a man whose development has been arrested; on the contrary, he is a man who has given himself a chance of continuing to develop long after most adults have muffled themselves in the cocoon of middle-aged habit and convention. Aldous Huxley
I felt that I was dying, and perhaps I did die a little, or rather began to die in the way that the cocoon of the chrysalis cracks at the end of winter; but unfortunately I did not die so thoroughly that I achieved new life like a butterfly. Halldór Laxness
The mind can weave itself warmly in the cocoon of its own thoughts, and dwell a hermit anywhere. James Russell Lowell
