Cutting Thin Our Spiritual Bread

After Bobby's comment on "Approved for Eternity" I recalled this in Walden.  Of course we can see the whole book as a kind of answer to the jellyfish scientist's proposition that humanity does not have the "heart" for immortality and will not until we "love" nature.

The very simplicity and nakedness of man's life in the primitive ages imply this advantage, at least, that they left him still but a sojourner in nature. When he was refreshed with food and sleep, he contemplated his journey again. He dwelt, as it were, in a tent in this world, and was either threading the valleys, or crossing the plains, or climbing the mountain-tops. But lo! men have become the tools of their tools. The man who independently plucked the fruits when he was hungry is become a farmer; and he who stood under a tree for shelter, a housekeeper. We now no longer camp as for a night, but have settled down on earth and forgotten heaven. We have adopted Christianity merely as an improved method of agri-culture. We have built for this world a family mansion, and for the next a family tomb. The best works of art are the expression of man's struggle to free himself from this condition, but the effect of our art is merely to make this low state comfortable and that higher state to be forgotten....

In this course which our ancestors took there was a show of prudence at least, as if their principle were to satisfy the more pressing wants first. But are the more pressing wants satisfied now? When I think of acquiring for myself one of our luxurious dwellings, I am deterred, for, so to speak, the country is not yet adapted to human culture, and we are still forced to cut our spiritual bread far thinner than our forefathers did their wheaten. Not that all architectural ornament is to be neglected even in the rudest periods; but let our houses first be lined with beauty, where they come in contact with our lives, like the tenement of the shellfish, and not overlaid with it. But, alas! I have been inside one or two of them, and know what they are lined with.
