The Shape of Design by Frank Chimero

I could read this book 100 times.

"Design’s ability to connect requires it to be in the middle position. The work’s qualities are defined by the characteristics of what surrounds it, like how the negative space between two closely placed parallel lines creates a third line. We’re that third line, frequently shifting in order to serve and respond to the elements around us. As the elements connected by design change, so, too, does the design. The field is in flux, always being neither this nor that, which makes it frustrating to try to pin down. It is, like all shape-shifters, evasive and slippery."
