When I was ill, my conversation was not devoted to the sufferings of my body, nor did I chatter about such matters to those who visited me but I continued to discuss the main elements of natural philosophy as before, and this point especially, how it is that the mind, while being aware of the agitations in our poor flesh, is unperturbed and preserves its specific good. Nor did I allow the doctors to assume grand airs, as though they were engaged in something important, but my life proceeded as well and happily as ever.
