TUESDAY is the bicentenary of the birth, in Portsmouth, England, of Charles Dickens, literature’s greatest humanist. We can rejoice that so many of the evils he assailed with his beautiful, ferocious quill — dismal debtors’ prisons, barefoot urchin labor, an indifferent nobility — have happily been reformed into oblivion. But one form of wickedness he decried haunts us still, proud and unrepentant: the lawyer.

Lawyers appear in 11 of his 15 novels. Some of them even resemble humans.
