The Nature of "Building"

Harry Bingswanger has a great piece rebutting Obama's "You Didn't Build That" speech.  I particularly liked this observation:

If you do not create everything, you create nothing.

Since Thomas Edison didn’t discover electricity, invent glass, learn how to forge metal, and devise language, he didn’t invent the light bulb. An artist doesn’t create a painting because the pigments are already there on his palette. A child putting together Lego blocks is not building anything because the Lego blocks were provided for him.

The only act that would count as creation is making something out of nothing–creation ex nihilo.
