"But the Truth is, my Thoughts never look towards Dublin now, without casting such a Cloud upon my Mind, and laying such a Load of fresh Sorrow on me for the Loss of my dear Friend, your Brother, that I cannot without Displeasure turn them that Way; and when I do it I find my self very unfit for Conversation and the Entertainment of a Friend."
— Locke, John (1632-1704)
