Diderot is accosted by this curious being one afternoon on a bench in front of the Cafe de la Regence in the Palais Royal. They proceed in the thoroughly natural and easy manner of interlocutors in a Platonic dialogue. It is not too much to say that _Rameau's Nephew_ is the most effective and masterly use of that form of discussion since Plato. Diderot's vein of realism is doubtless in strong contrast with Plato's poetic and idealising touch. Yet imaginative strokes are not wanting to soften the repulsive theme, and to bring the sordid and the foul within the sphere of art. For an example. "Time has passed," says Rameau, "and that is always so much gained." "_I._--So much lost, you mean. "_He._--No, no; gained. People grow rich every moment; a day less to live, or a crown piece to the good, 'tis all one. When the last moment comes, one is as rich as another. Samuel Bernard, who by pillaging and stealing and playing bankrupt, leaves seven-and-twenty million francs in gold, is no better than Rameau, who leaves not a penny, and will be indebted to charity for a shroud to wrap about him. The dead man hears not the tolling of the bell; 'tis in vain that a hundred priests bawl dirges for him, in vain that a long file of blazing torches go before. His soul walks not by the side of the master of the funeral ceremonies. To moulder under marble, or to moulder under clay, 'tis still to moulder. To have around one's bier children in red and children in blue, or to have not a creature, what matters it?" These are the gleams of the _mens divinior_, that relieve the perplexing moral squalor of the portrait. Even here we have the painful innuendo that a thought which is solemnising and holy to the noble, serves equally well to point a trait of cynical defiance in the ignoble.
