Mr. Casaubon had never put any question concerning the nature of his illness to Lydgate, nor had he even to Dorothea betrayed any anxiety as to how far it might be likely to cut short his labors or his life. On this point, as on all others, he shrank from pity; and if the suspicion of being pitied for anything in his lot surmised or known in spite of himself was embittering, the idea of calling forth a show of compassion by frankly admitting an alarm or a sorrow was necessarily intolerable to him. Every proud mind knows something of this experience, and perhaps it is only to be overcome by a sense of fellowship deep enough to make all efforts at isolation seem mean and petty instead of exalting.
