> “Into the innermost recesses of nature –” > Oh, you philistine! > “No created spirit can penetrate, > Happy the one to whom she shows only > the outer shell." > I have heard this repeated for sixty years, > I curse it, but furtively; > Tell me a thousand, a thousand times: > She gives everything abundantly and gladly; > Nature has neither core > nor shell, > She is all at once everything. > Only you, most of all, test her, > Whether you are core or shell.
