The fact that distinguished Charles Lamb from other men was his entire devotion to one grand and tender purpose. There is, probably, a romance involved in every life. In his life it exceeded that of others. In gravity, in acuteness, in his noble battle with a great calamity, it was beyond the rest. Neither pleasure nor toil ever distracted him from his holy purpose. Everything was made subservient to it. He had an insane sister, who, in a moment of uncontrollable madness, had unconsciously destroyed her own mother; and to protect and save this sister--a gentle woman, who had watched like a mother over his own infancy--the whole length of his life was devoted. What he endured, through the space of nearly forty years, from the incessant fear and frequent recurrence of his sister's insanity, can now only be conjectured. In this constant and uncomplaining endurance, and in his steady adherence to a great principle of conduct, his life was heroic. We read of men giving up all their days to a single object--to religion, to vengeance, to some overpowering selfish wish; of daring acts done to avert death or disgrace, or some oppressing misfortune. We read mythical tales of friendship; but we do not recollect any instance in which a great object has been so unremittingly carried out throughout a whole life, in defiance of a thousand difficulties, and of numberless temptations, straining the good resolution to its utmost, except in the case of our poor clerk of the India House. This was, substantially, his life. His actions, thoughts, and sufferings were all concentred on this one important end. It was what he had to do; it was in his reach; and he did it, therefore, manfully, religiously. He did not waste his mind on too many things; for whatever too much expands the mind weakens it; nor on vague or multitudinous thoughts and speculations; nor on dreams or things distant or unattainable. However interesting, they did not absorb him, body and soul, like the safety and welfare of his sister.
