without effort and without thought, knitting for her children. Now
stockings are good and comfortable things, and the children will
undoubtedly be much the better for them; but surely it would be
short-sighted, to say the least of it, to depreciate this toiling mother
as a mere stocking-machine--a mere provider of physical comforts?

However, there are blind leaders of the blind, and not a few of them,

they may have telegraphs to Saturn, and see the other side of the moon,
