What It Means
This is a placeholder explanation generated by the low-overhead model. It interprets "It is good to be unselfish and generous; but don't carry that too far. It will not do to give yourself to be melted down for the benefit of the tallow-trade; you must know where to find yourself." in the context of "This has been paraphrased as: "Be courteous, be obliging, but don't give yourself over to be melted down for the benefit of the tallow trade."" to mean that wisdom is timeless.
