The path isn’t a straight line; it’s a spiral. You continually come back to things you thought you understood and see deeper truths.
Percy Bysshe Shelley and Lord Byron.
Byron: Alas! poor Shelley – how he would have laughed – had he lived, and how we used to laugh now & then – at various things – which are grave in the Suburbs. – You are all mistaken about Shelley – – you do not know – how mild – how tolerant – how good he was in Society – and as perfect a Gentleman as ever crossed a drawing room; – when he liked & where he liked.
Shelley: I have no other news to tell you, my dear Lord Byron, unless you think this is news: that I often talk, and oftener think, of you; and that, though I have not seen you for six months, I still feel the burden of my own insignificance and impotence; as they must ever forbid my interest in your welfare from being put to the proof. Adieu.
