I promised Todd [Willingham] that I would attend the execution. . . . It was impossible for me to go. I was incapable of that sort of travel. Sitting in a chair that long, driving to Huntsville just wouldn't have happened. . . . I'm sure I would have been there. It's something I know. I would not have denied him that, but the accident kept me from being there. At some level, the universe was giving me the excuse for not being there. . . . The universe was like, "Oh, you don't have to watch this. ". . . It would have been a horrible thing, but I'm sure I would have gone.
Theodor Schwann
The elementary parts of all tissues are formed of cells in an analogous, though very diversified manner, so that it may be asserted, that there is one universal principle of development for the elementary parts of organisms, however different, and that this principle is the formation of cells.
