That should read:

and f(y) is the result of excitation y, then the result of excitation
(x + y) is f(x) + f(y). . .

I apologize for the error. Thanks very much to David Ryeburn for
spotting it.

I guess that's the definition of linearity. I'm not sure I've heard
it called superposition before, but rather that the superposition
theorem is a direct result of the linearity of a system. I trust
that's a small definitional issue that doesn't really change what
you're saying.
Cheers,
Tom
