An Engineering Kind of Quote

This excerpt from the book "The Paradise of Bombs" by Scott Russell Sanders (University of Georgia Press) made me look at the world a little differently. (There's a moral lesson in the quote, too.) I'd really never thought about the importance of engineering before reading this:

"There is a mystical virtue in right angles. There is an unspoken morality in seeking the level and the plumb. A house will stand, a table will bear weight, the sides of a box will hold together only if the joints are square and the members are upright. When the bubble is lined up between two marks etched in the glass tube of the level, you have aligned yourself with the forces that hold the universe together."
